Precision Injection: A Guide to Volvo D13 Fuel Injectors
The Critical Role of Precision Fuel Delivery
Volvo D13 injectors are essential components that directly impact your fleet's performance, fuel efficiency, and operational costs. For fleet managers seeking reliable information, here's what you need to know:
The Volvo D13 engine powers countless commercial fleets across North America, and its fuel injection system plays a pivotal role in maintaining optimal performance. When these precision components fail, the impact can be immediate and costly.
"Better fuel efficiency starts right here," is how Volvo describes their injection system, and for good reason. These high-pressure injectors are engineered to deliver precise amounts of fuel at exactly the right moment, ensuring complete combustion while minimizing emissions and maximizing power output.
Many fleet managers face the decision between purchasing individual injectors or complete six-pack kits. The research clearly shows that replacing all six injectors simultaneously provides more consistent engine performance and reduces future downtime, often paying for itself within the first year through improved fuel efficiency.
Whether you're experiencing symptoms of injector failure or planning preventative maintenance, understanding these components is the first step toward making informed decisions that keep your fleet running efficiently.
Understanding the Volvo D13 Injector
When you peek under the hood of a Volvo truck, the Volvo D13 injector might not immediately catch your eye, but this small component is truly the unsung hero of your engine's performance. These precision-engineered marvels form the beating heart of your truck's fuel delivery system, designed to thrive in the punishing conditions that commercial drivers face every day.
Think of your Volvo D13 injector as a highly skilled bartender – one that pours exactly the right amount of fuel, at precisely the right moment, thousands of times per minute. This precision isn't just impressive – it's essential. Even the slightest variation in timing (we're talking microseconds here) can impact your truck's power, fuel efficiency, and emissions.
What makes these injectors so special is their sophisticated design. Each one contains a responsive solenoid-actuated valve, a nozzle with multiple spray holes machined to incredibly tight tolerances, internal plungers and barrels that create the necessary high pressure, and specialized seals that keep everything where it belongs – preventing the nightmare scenario of coolant mixing with your fuel system.
The D13 engine's common rail system maintains pressure up to an astounding 35,000 PSI – that's about 1,200 times the pressure in your average car tire! This incredible pressure allows for multiple injection events during each combustion cycle, a sophisticated approach that helps your truck meet strict emissions standards while still delivering the power you need to haul heavy loads.
The Role of the Volvo D13 Injector in Engine Performance
Your Volvo D13 injectors aren't just delivering fuel – they're orchestrating a complex performance that affects every aspect of your engine's operation.
When it comes to combustion efficiency, these injectors are true artists. By atomizing diesel into a fine, consistent mist, they ensure complete fuel burning. It's like the difference between trying to start a campfire with a log versus kindling – that fine spray ignites more completely, maximizing your power while minimizing black smoke and harmful emissions.
Power delivery becomes smoother and more responsive thanks to the injector's ability to perform multiple precisely timed injection events per cycle. This sophisticated choreography allows your Volvo to deliver peak torque at lower RPMs – exactly what you need when you're pulling a heavy load uphill.
As for fuel economy – well, that's where many fleet owners see the most tangible benefit. Modern Volvo D13 injectors deliver exactly the right amount of fuel needed for each situation, no more and no less. As one fleet manager told us, "After upgrading to remanufactured OEM injectors across our fleet of 15 Volvo trucks, we saw a measurable 3-4% improvement in fuel economy. On long-haul routes, that translates to thousands of dollars saved annually per truck."
These injectors also play a crucial role in your emissions control system, working in harmony with your EGR and aftertreatment components to keep your truck running clean and compliant with increasingly strict regulations.
Key Features of the Volvo D13 Fuel Injector
What sets the Volvo D13 fuel injector apart from previous generations is its remarkable engineering. These aren't your grandfather's diesel injectors!
The high-pressure capability of these injectors is truly impressive. They operate reliably at pressures that would destroy lesser components, creating the fine atomization that's essential for efficient combustion and clean burning.
Unlike older diesel engines that delivered a single shot of fuel per cycle (think old-school pump shotgun), the D13 injectors deliver multiple precisely timed injection events – a pilot injection, main injection, and post injection. This is more like a semi-automatic approach that creates smoother combustion, quieter operation, and better emissions control.
The precision manufacturing behind each injector would make a Swiss watchmaker proud. The clearance between the plunger and barrel is measured in microns – thinner than a human hair. This incredible precision requires sophisticated manufacturing techniques that few companies can match.
The electrical control system uses fast-acting solenoids that respond instantly to signals from your engine's ECM, allowing for real-time adjustments to optimize performance whether you're climbing a mountain pass or cruising on the interstate.
Built for the long haul, these injectors use high-grade materials that resist wear and corrosion, even when exposed to varying fuel qualities across different regions. This durability is crucial for components that must perform reliably for hundreds of thousands of miles in all conditions.
When it comes time to replace these critical components, choosing quality remanufactured injectors from a trusted source like G2 Diesel Products ensures you'll get OEM-level performance without breaking the bank.
Benefits of Using OEM Remanufactured Fuel Injectors
When the time comes to replace your Volvo D13 injectors, you'll face an important decision that impacts both your wallet and your truck's performance. At G2 Diesel Products, we've worked with countless fleet managers and owner-operators who have finded the substantial advantages of choosing OEM remanufactured injectors over aftermarket alternatives.
The cost savings alone make remanufactured injectors worth considering. Our OEM remanufactured Volvo D13 injectors typically cost 30-40% less than brand new units, which translates to thousands of dollars saved when replacing a complete set of six injectors. For many of our customers operating on tight margins, these savings make all the difference—without sacrificing the quality and reliability their business depends on.
But cost isn't the only factor that matters. The quality assurance process we implement at G2 Diesel Products ensures that every remanufactured injector performs to the highest standards. We completely disassemble each unit, thoroughly inspect every component, and replace all wear parts with premium components. Nothing leaves our facility without passing the same rigorous testing regiment as new factory units. In fact, our injectors must meet or exceed OE specifications before they earn our stamp of approval.
Many of our customers are surprised to learn that remanufactured Volvo D13 injectors can actually outperform their original injectors. This performance boost happens because our remanufacturing process often incorporates design improvements that address known issues in earlier versions. It's like getting an upgraded version that benefits from everything engineers have learned since your truck was first built.
There's also an environmental angle that many of our customers appreciate. By reusing the core components of your injectors, the remanufacturing process conserves valuable resources and requires significantly less energy than manufacturing brand new units.

The Remanufacturing Process Ensuring Quality
When your truck's engine depends on perfect fuel delivery, the quality of remanufactured Volvo D13 injectors becomes absolutely critical. At G2 Diesel Products, we don't just refurbish injectors – we transform them through a meticulous process that brings each component back to life with precision and care.
Ever wondered what happens when your old injector arrives at our facility? First, our technicians completely disassemble it, carefully separating each component for individual inspection. This isn't a quick once-over – it's a detailed examination where even the smallest imperfections are identified. Think of it as giving your injector a complete physical, where nothing escapes our attention.
"I've been taking apart and rebuilding these injectors for over a decade, and I still find it amazing how much performance we can restore through our process," shares Mike, one of our senior technicians at our Harrisburg facility.
Next comes the cleaning – but not just any cleaning. We use specialized ultrasonic baths that create microscopic bubbles that implode against surfaces, removing even the most stubborn carbon deposits and varnish buildup. It's like giving your injector components a deep-tissue massage that reaches places no conventional cleaning could touch.
The nozzles – arguably the most critical part of any Volvo D13 injector – undergo our extrude honing process. This specialized technique ensures perfect flow matching between injectors, maintaining the exact spray pattern specifications that Volvo engineers originally designed. When your engine fires up, each cylinder receives precisely the same fuel delivery – no more, no less.
For perfect sealing, we precision lap all mating surfaces. This meticulous process prevents those frustrating leaks between the high-pressure fuel system and your engine's cooling system – a common headache with worn injectors that can lead to costly repairs if left unchecked.
Of course, some parts simply need replacing. All wear components – the O-rings, seals, tips, and electrical connectors – are swapped out with new parts that meet or exceed OE specifications. In many cases, these new components actually improve on the original design, addressing known weak points in earlier versions.
Assembly happens in our clean-room environment – a space that's free from dust and contaminants that could compromise performance. Each injector is carefully calibrated to ensure proper valve lift and travel, critical factors in achieving the precise fuel delivery your engine needs.
"Each injector is verified for delivery, response time, and peak injection pressures to ensure it meets or exceeds OE standards. This rigorous testing process is what separates quality remanufactured injectors from inferior alternatives."
The final step? Testing – and lots of it. We put each Volvo D13 injector through a gauntlet of 42 functional tests that simulate real-world engine conditions. We check for tip seat leakage, verify valve operation, examine plunger and barrel leakage, confirm timing plunger accuracy, and measure delivery, response time, and peak injection pressures. It's exhaustive, but necessary to ensure you get an injector that performs flawlessly.
"We're not just cleaning and reassembling these injectors," explains our lead testing technician. "We're bringing them back to original specifications and often improving them with updated components. The testing phase is where we verify that each injector will perform exactly as expected when installed in a customer's engine."
This commitment to quality is why fleet managers across North America trust G2 Diesel Products for their Volvo D13 injector needs. When performance, reliability, and value matter, our remanufacturing process delivers results you can count on mile after mile.
Signs of Fuel Injector Failure in the Volvo D13 Engine
Your truck's performance speaks volumes, and when Volvo D13 injectors start to fail, your engine has ways of letting you know. Catching these warning signs early can save you thousands in repairs and prevent those dreaded roadside breakdowns that eat into your profits.
That rough idle you're feeling when you're waiting at the loading dock? It's not just an annoyance—it's your engine's first cry for help. When Volvo D13 injectors aren't delivering fuel precisely as designed, the engine struggles to maintain a smooth idle, creating that distinctive shake and vibration that experienced drivers immediately recognize as trouble.
During acceleration, pay close attention to how your truck responds. A healthy D13 engine delivers power smoothly and predictably. When you press the pedal and feel hesitation, stumbling, or a noticeable lack of power, your injectors may be telling you they're not up to the job anymore. This misfiring happens when fuel delivery timing or quantity is off—even by milliseconds—disrupting the carefully orchestrated combustion process.
"I knew something was wrong when my fuel card statements started climbing even though I was running the same routes with similar loads," says Mike, a long-haul owner-operator from Pennsylvania. "By the time I noticed the hesitation on hills, I was already burning an extra 30 gallons a week."
This increased fuel consumption is a telltale sign that your Volvo D13 injectors need attention. When injectors leak or deliver incorrect amounts of fuel, your efficiency drops noticeably. For fleet managers watching every penny, this often serves as the first red flag.
The color of your exhaust provides valuable clues too. Excessive white smoke, especially during cold starts, suggests unburned fuel passing through the system. Black smoke typically points to too much fuel or poor atomization—both classic symptoms of injector issues. Either way, your truck is literally showing you that something's not right under the hood.
Morning startups can reveal problems too. When you turn the key and the engine cranks longer than usual or struggles to catch, failing injectors could be the culprit. This hard starting becomes more pronounced in cold weather, when precise fuel delivery becomes even more critical.
Modern Volvo trucks don't leave you guessing—their sophisticated diagnostic systems monitor injector performance constantly. When the check engine light illuminates or specific fault codes appear, it's time to take action. These warning systems exist to help you address problems before they escalate into major repairs.
Listen carefully to your engine too. Unusual knocking, tapping, or clattering sounds—especially under load or during acceleration—often point to injector problems. These sounds occur when combustion timing is off, creating pressure spikes in the cylinder at the wrong moments.
Perhaps the most serious symptom is cross-contamination between your cooling and fuel systems. If you notice fuel in your coolant (often appearing as an oily film on top) or coolant in your fuel (causing white smoke with a sweet smell), your injector cups may be failing. This requires immediate attention to prevent serious engine damage.
Common Symptoms & Causes of Volvo D13 Injector Cup Failure
Injector cups deserve special attention in the D13 engine. These components seal the injector to the cylinder head, and their failure allows coolant to enter the combustion chamber or fuel to contaminate the cooling system. If you're losing coolant without visible leaks or notice white exhaust smoke with that distinctive sweet smell, have your injector cups checked right away. Catching this early can prevent catastrophic damage to your engine.
"What impressed me was how quickly things improved after replacing my injectors," shares Tom, a regional fleet manager. "The truck went from being our problem child to one of our most reliable units overnight. The fuel savings alone covered a big chunk of the repair cost within the first few months."
By staying alert to these warning signs and addressing injector issues promptly, you'll keep your Volvo D13 engine running efficiently for hundreds of thousands of miles—exactly what you need from the powerplant that drives your business forward.
Cost Implications and Core Return Process for Replacing Injectors
Let's talk money – because when it comes to Volvo D13 injector replacement, understanding the financial side helps you make smarter decisions for your fleet's bottom line.
Replacement Costs
One question we hear all the time is whether to replace just the failed injector or go for the whole set. While your wallet might initially prefer replacing just one, there's a strong case for replacing all six at once.
Think of it like this – those injectors have been working together since day one. They've experienced the same fuel, temperatures, and operating conditions. When one fails, the others are likely not far behind. Installing a complete set ensures balanced performance across all cylinders, which means smoother operation and better fuel economy.
Plus, there's the downtime factor. Every hour your truck sits in the shop costs you money. Replacing all injectors during one service visit can prevent multiple repair sessions down the road. Many of our customers find that the improved fuel efficiency from a matched set of injectors actually pays for itself within the first year.
Core Charges and Return Process
When you buy remanufactured Volvo D13 injectors, you'll encounter something called a core charge system. Don't worry – it's simpler than it sounds.
Here's how it works: When you purchase your remanufactured injectors, we add a core charge (usually about $300 per injector) to your bill. This is basically a deposit that you get back when you return your old injectors.
You'll have 30 days to ship those old injectors (we call them cores) back to us. To make this easy, we'll email you a prepaid shipping label – just package up those old injectors carefully and send them our way.
Once we receive your cores, our team inspects them to ensure they match the part numbers you purchased and that they're in rebuildable condition. If everything checks out, we'll process your refund, typically within 30 days of receiving the cores.
Financing Options
At G2 Diesel Products, we understand that dropping several thousand dollars at once isn't always feasible for every operation. That's why we offer several financing options to help spread out the cost:
Our Pay in 4 option is perfect for smaller purchases between $30 and $1,500, letting you split the cost into four equal payments with zero interest. For larger investments between $49 and $10,000, our Pay Monthly plans offer installment options ranging from 3 to 24 months, with APRs between 9.99% and 35.99%.
We also have additional flexible payment plans for purchases ranging from $15 to $15,000, with various installment structures to fit your budget.
One of our long-time customers, a fleet manager from Pennsylvania, shared his experience: "We initially balked at replacing all six injectors when only two were showing problems. But after calculating the downtime costs and potential for additional failures, we opted for the complete set. The fuel efficiency improvement alone saved us about $2,200 per truck in the first year."
Making the right choice now can save you significant money and headaches down the road. It's why so many fleet managers trust G2 Diesel Products for their injector needs.

Maintenance Tips to Prevent Injector Failures
Taking care of your Volvo D13 injectors isn't just about saving money—it's about keeping your truck running smoothly mile after mile. I've talked with dozens of fleet managers and owner-operators who've learned (sometimes the hard way) that prevention truly is better than cure when it comes to these precision components.
Use High-Quality Fuel
The fuel you choose has a direct impact on your injectors' lifespan. Think of it like your own diet—quality matters! High-quality diesel from reputable stations gives your engine the clean nutrition it needs, while bargain fuel might contain contaminants that slowly damage those precision injector components.
"I learned this lesson after two injector replacements in six months," shares Mike, a long-haul driver from Ohio. "Now I'm picky about where I fuel up, and I haven't had injector problems since."
Consider adding a quality fuel additive specifically designed for common rail systems, especially during winter months. These additives can help keep your injectors clean and prevent the formation of deposits that restrict fuel flow. Just remember that with biodiesel blends, it's best to stick with B5 (5% biodiesel) or lower unless Volvo specifically approves higher concentrations for your engine.
Implement Regular Fuel Filter Maintenance
Your fuel filters are the bouncers at the club, keeping unwanted particles from crashing your injector party. Replacing these filters according to schedule—or even earlier if you operate in dusty environments—is one of the most cost-effective ways to protect your injectors.
Don't forget to drain water separators regularly. Water in your fuel system is like rust on a classic car—it might start small, but the damage compounds quickly. Many drivers set a simple reminder on their phone to check water separators weekly, especially during humid months when condensation is more likely to occur.
Monitor and Manage Engine Temperature
Heat is the silent killer of Volvo D13 injector cups. When engine temperatures climb too high, the metal around those injector cups expands at different rates, potentially creating gaps where coolant can seep into places it shouldn't go.
Maintaining your cooling system with the proper coolant mixture and regular fluid changes is essential. Some experienced operators have found that installing a manual fan switch provides extra cooling during challenging conditions like long uphill climbs or summer heat waves.
"If you wanna make those cups live longer, don't let your motor get so hot," advises Terry, a 20-year Volvo technician. "Setup a manual fan switch and keep it cooler on pulls. Those localized head temperatures can shoot past 220°F if you're not careful, and that's when cups start to fail."
Adhere to Recommended Oil Change Intervals
Quality engine oil doesn't just lubricate your engine—it also affects your high-pressure fuel pump, which directly impacts injector performance. Following Volvo's recommended oil change schedule based on your specific application isn't just a suggestion—it's essential protection for your entire fuel system.
Always use oil grades that meet Volvo's VDS (Volvo Drain Specification) requirements. These specially formulated oils provide the right protection for your engine's unique needs. Many successful fleet operators also implement oil analysis programs to catch potential issues before they escalate into injector problems.
Proactive Diagnostics
Modern diagnostic tools can identify struggling injectors before they fail completely. Regular cylinder contribution tests can spot underperforming cylinders, often the first sign of injector issues. Many shops offer this service for a reasonable fee, and it's worth every penny when it prevents a roadside breakdown.
Pay attention to your fuel economy numbers, too. A sudden increase in consumption might be your truck's way of telling you that an injector isn't atomizing fuel properly. And never ignore check engine lights—what starts as a minor issue can quickly escalate to injector damage if left unaddressed.
Professional Inspections
Even with the most diligent DIY maintenance, there's still value in professional eyes on your fuel system. Annual fuel system inspections by qualified technicians can catch issues that might not be obvious to even experienced drivers.
Consider having your injectors ultrasonically cleaned every 250,000 miles as preventative maintenance. It's significantly cheaper than replacement and can extend injector life considerably. This service removes internal deposits that form gradually and restrict proper fuel flow.
"We implemented a proactive injector cleaning program at the 250,000-mile mark for our entire Volvo fleet," explains Sarah, a fleet maintenance manager with 35 trucks. "Since starting this approach, we've cut roadside injector failures by almost 80% and added about 200,000 miles to our average injector lifespan. The math makes sense—prevention is always cheaper than emergency repairs."
By following these maintenance practices consistently, you'll not only extend the life of your Volvo D13 injectors but also maintain better fuel economy, reduce downtime, and keep your engine running at peak performance. That's what we at G2 Diesel Products call a win-win-win situation.
Frequently Asked Questions about Volvo D13 Injectors
How often should Volvo D13 injectors be replaced?
The lifespan of Volvo D13 injectors isn't set in stone. Think of them like tires - their longevity depends on how you drive, where you drive, and how well you maintain them. With proper care, many injectors will faithfully serve you for 350,000 to 500,000 miles.
Most fleet owners take one of three approaches to injector maintenance:
Some folks wait until something breaks before fixing it - the reactive approach. While this saves money upfront, it's a bit like waiting for your check engine light before changing your oil. When an injector fails unexpectedly, you're looking at towing costs, emergency repair rates, and that sinking feeling of being stranded on the roadside.
Others follow a schedule, replacing injectors around the 350,000 to 400,000-mile mark regardless of symptoms. It's like replacing your roof before it leaks - you might be doing it a bit early, but you're avoiding potential disaster.
The most sophisticated fleets use diagnostic tools to track injector performance over time, watching for subtle signs of degradation before problems become obvious. This approach gives you the best of both worlds - maximum component life without unexpected breakdowns.
At G2 Diesel Products, we typically suggest considering a full set replacement around 400,000 miles, especially if you've noticed even minor symptoms or if your routes involve heavy loads or extreme conditions. Think of it as preventative medicine for your engine.
Can I replace only one injector, or should I replace all six?
This question comes up in nearly every conversation about Volvo D13 injectors. Yes, technically you can replace just one injector, but there are compelling reasons why most experienced fleet managers choose to replace the complete set:
Injectors are like teammates - they work together and wear out together. When one fails, the others are likely not far behind. Balanced performance across all cylinders is critical for optimal engine operation, and modern injectors are carefully flow-matched at the factory. Mixing old and new injectors is like putting a new tire alongside five worn ones - the vehicle just won't run right.
The labor costs to access injectors represent a significant portion of the total repair bill. When you consider that you're paying for most of that labor whether you're replacing one injector or all six, the economics start to make sense.
One fleet manager from Ohio told me, "After replacing just one injector and then having to come back to the shop twice more in the next six months for the same job, I did the math. The three separate repair bills cost me nearly twice what a complete set would have cost, not to mention the downtime and towing."
The fuel economy improvement from a fresh set of properly matched injectors often pays for the additional cost within 8-12 months of highway operation. That's money back in your pocket mile after mile.
What is the warranty on remanufactured Volvo D13 injectors?
When you purchase remanufactured Volvo D13 injectors from G2 Diesel Products, they come with a one-year/unlimited-mile warranty when installed by an authorized dealer. This isn't just a piece of paper - it's our promise that these components will perform as expected.
The warranty covers the things you'd expect: defects in materials and workmanship, normal wear and tear under recommended conditions, and replacement if something goes wrong. Like any warranty, there are reasonable exclusions - damage from contaminated fuel, improper installation, or modifications to your engine or fuel system won't be covered.
To keep your warranty intact, make sure qualified technicians handle the installation, follow the recommended maintenance schedule, address any fuel system contamination before installation, and keep records of the work done. These simple steps protect both your injectors and your investment.
I remember speaking with a customer who initially questioned the value of remanufactured injectors. Six months later, he called to say, "I was skeptical at first, but these injectors have been performing flawlessly. The peace of mind from knowing I'm covered for a full year made the decision much easier."
How can I distinguish between injector failure and other engine issues?
When your engine isn't running right, it's tempting to jump to conclusions about the Volvo D13 injectors, but similar symptoms can have different causes. Here's how to become a better detective:
Modern Volvo engines are equipped with sophisticated diagnostics that often identify specific injector issues. Diagnostic Trouble Codes like P0201 through P0206 typically point to problems with specific injector circuits. These codes are like your engine's way of telling you exactly what hurts.
A cylinder contribution test measures how much each cylinder contributes to overall engine power. If cylinder #3 is significantly underperforming compared to the others, that's a strong clue the injector might be the culprit.
The exhaust smoke from your stack tells a story too. Brief white smoke during a cold start is usually normal - like morning breath for your engine. Persistent white smoke often indicates leaking injectors, while black smoke suggests an injector might be stuck open and dumping too much fuel.
Abnormal fuel rail pressure might indicate issues with the high-pressure pump rather than the injectors themselves. And if you find fuel in your coolant, the problem is more likely with the injector cups than the injectors.
As one G2 Diesel Products technician explained, "We always take a systematic approach to diagnosis. About one in five suspected injector failures turns out to be something else entirely - fuel pump issues, pressure regulator problems, or even simple wiring harness faults. Taking the time to properly diagnose saves our customers thousands in unnecessary parts."
What causes premature injector failure in Volvo D13 engines?
Volvo D13 injectors are precision instruments, and several factors can shorten their lifespan. Understanding these enemies can help you protect your investment:
Fuel contamination is perhaps the biggest threat. Water, dirt, and debris in your fuel act like sandpaper inside these precisely machined components. Every particle that makes it past your filters causes a tiny amount of damage that accumulates over time.
Excessive heat is particularly problematic for D13 engines. When engine temperatures climb too high, injector seals and cups can deteriorate, leading to leaks and eventual failure. This is why proper cooling system maintenance is just as important for injector health as fuel system care.
Fuel quality varies widely across regions and suppliers. Fuel with poor lubricity properties doesn't properly protect the moving parts inside injectors, while high sulfur content can cause corrosion and deposits. Your injectors are only as good as the fuel you feed them.
Electrical issues, extended idling periods, and neglected maintenance all contribute to premature failure. Even running high biodiesel blends can affect injector performance in some D13 engines.
One veteran driver I spoke with summed it up perfectly: "These engines are like elite athletes - they perform amazingly when given the right conditions, but they need quality fuel, regular maintenance, and proper operating temperatures. Cut corners on any of these, and performance suffers."
By addressing these factors through proper maintenance, quality fuel, and smart operating practices, you can significantly extend the life of your injectors and avoid the headaches of unexpected failures.
