We only sell engines. A Volvo D13 engine for sale is one of the modern diesels we get asked about most, by fleets, owner operators, coach companies and repair shops who want a reliable engine without paying new price.
This guide covers the D13 specs, the trucks and coaches it fits, the different generations, the emissions system, the common problems, how we test and how buying from us works.
Why a Volvo D13 Engine for Sale Makes Sense
Volvo introduced the D13 in Europe in the mid 2000s and brought it to North America for 2007, replacing the D12. It is a 12.8 litre inline six with an overhead camshaft, unit injectors and a variable geometry turbo. It was built to be light for its size, efficient and easy to service, and it has been updated many times since to meet new emissions and fuel economy rules.
Today it powers Volvo VNL and VNR highway trucks, VHD vocational trucks, the European FH and FM ranges, and many Prevost coaches. That huge spread means there is a big supply of good used engines and a big demand for them too.
A new D13 is expensive and lead times can be long. A tested Volvo D13 engine for sale gives you the same modern engine for much less, and your truck or coach can be working again in days.

The D13 shares its basic design with the Mack MP8, which is built on the same platform. The two are related but not directly interchangeable, so tell us which one you have when asking about a Volvo D13 engine for sale.
Which Trucks and Coaches Use the D13?
The D13 is used across the Volvo Group:
- Volvo VNL, VNM, VNR and VNX highway trucks
- Volvo VHD and VAH vocational and auto hauler trucks
- Volvo FH, FM and FMX trucks in Europe, Africa, Asia and the Middle East
- Prevost coaches, including the H3-45 and X3-45
- Volvo buses and some industrial and marine versions
The Volvo VNL is the most common North American home for the engine, while the European ranges use their own versions. Because mounts, wiring, cooling and aftertreatment differ between markets and years, we always ask about your vehicle before quoting a Volvo D13 engine for sale.
D13 Generations Explained
EPA07. The first North American D13 engines used cooled EGR and a diesel particulate filter, without DEF. They are found in trucks from about 2007 to 2010.
EPA10. From 2010 Volvo added selective catalytic reduction with DEF. This improved fuel economy and became the base for later engines.
GHG14. Around 2013 to 2014 the engine was updated for greenhouse gas rules with changes to the turbo, software and other parts.
GHG17 and D13TC. From around 2017 Volvo updated the engine again and offered a turbo compound version, the D13TC, which recovers energy from the exhaust to boost torque and economy.
Euro versions. Engines for Europe and other markets carry names such as D13A, D13C and D13K, matched to Euro 3, 4, 5 and 6 rules.
Engines from different generations and markets are not always interchangeable. Matching the generation is the first thing we do with every Volvo D13 engine for sale.
The Emissions System
Depending on the year and market, the D13 uses cooled exhaust gas recirculation, a diesel oxidation catalyst, a particulate filter, a fuel doser for regeneration and selective catalytic reduction with DEF. Sensors and control modules watch all of it.
Many D13 faults that look like engine trouble are really aftertreatment problems, such as a clogged DPF, a bad NOx sensor or a failed DEF pump. Before you replace the engine, make sure the fault is inside it. If you do need a Volvo D13 engine for sale, you will usually keep your existing aftertreatment as long as it matches the engine generation.
Known D13 Weak Spots
The D13 is well built, but even a good Volvo D13 engine for sale has a few areas worth checking:
- EGR cooler and valve. Coolers can leak and valves can stick, causing coolant loss and derates.
- Turbo actuator. The variable geometry actuator can fail and cause power loss.
- DPF and doser. Lots of idling and short runs can clog the filter and the fuel doser.
- NOx sensors and DEF parts. Common causes of warning lights and derates.
- Crankcase ventilation. Breather problems can push oil out of seals.
- Injector sleeves. Worn sleeves can let coolant or combustion gas where it should not be.
- Oil and coolant leaks. Normal wear items on high mileage engines.
How We Test Every Volvo D13 Engine for Sale
Before any Volvo D13 engine for sale leaves our yard, we:
- Record the engine serial number, model code and rating from the plate.
- Read the engine computer where possible for hours, mileage and fault codes.
- Run a compression or cylinder cut-out test where the engine runs.
- Check the oil for coolant, fuel or metal.
- Run the engine where possible and check oil pressure, crankcase pressure and smoke.
- Check the turbo, its actuator and the engine brake.
- Photograph the engine from every side, including the data plate.
You get these results and photos with your quote. Read more in our guide to tested used engines.
What Comes With the Engine
Most of our D13 stock is sold as a complete engine, usually with the block, head, injectors, turbo, EGR parts, manifolds, oil pan and front cover. Some engines come with the engine computer. The aftertreatment is normally separate. Accessories vary from engine to engine.
We list exactly what is included on every quote. If you only need a long block, ask for that price.
Used, Rebuilt or Remanufactured?
Used engines come out of trucks and coaches and are sold after testing. They cost the least.
Rebuilt engines have new wear parts fitted, such as liners, pistons, rings, bearings and gaskets.
Remanufactured engines are restored to factory specifications throughout and cost the most.
Most buyers choose a tested used Volvo D13 engine for sale because good low mileage engines are available and the savings are big. We are happy to help you decide.
7 Checks Before You Buy Any Volvo D13 Engine for Sale
1. Match the generation and market
Before you pay for a Volvo D13 engine for sale, confirm it matches your vehicle’s year and emissions level. A Euro engine and a North American engine are not the same.
2. Check the computer
Know whether the engine computer is included and whether it will need programming.
3. Ask for fault codes and hours
A seller who tested their Volvo D13 engine for sale can share computer data along with compression or cut-out results.
4. Check for coolant in the oil
This can point to EGR cooler, oil cooler or sleeve problems.
5. Ask for real photos
Get pictures of the actual engine and data plate.
6. Know what is included
Two listings for a Volvo D13 engine for sale can look the same and still be very different once you count the turbo, EGR parts, computer and accessories.
7. Read the warranty
Know the length and what it covers. See our used engine warranty guide.
What Affects the Price
The price of a Volvo D13 engine for sale depends on the generation, the market version, the mileage, the condition and what comes with it. Newer GHG17 and turbo compound engines with low miles cost the most. Older EPA07 engines and some Euro versions usually cost less. Complete engines cost more than long blocks.
Freight also adds to the total. We include freight options with every quote. Our guide to replacement engine cost explains more.
Signs Your Truck Needs a Replacement Engine
Some D13 problems are simple fixes. These signs usually point to serious damage and lead buyers to look for a Volvo D13 engine for sale:
- A deep knock from the bottom end that grows under load
- Metal on the oil filter or drain plug
- Oil and coolant mixing that is not caused by a cooler
- Very high crankcase pressure and heavy blow-by
- Low oil pressure when warm
- A dropped valve or a damaged piston
Send us the symptoms and fault codes and we will tell you honestly whether repair or replacement makes more sense.
How Long Does a D13 Last?
A D13 that is serviced on time can run a million miles or more in highway work. Engines that die young usually suffered from coolant problems, bad fuel, overheating or long idling. Clean fuel, clean DEF and good coolant care make a big difference.
Habits that help a D13 last
- Change oil and filters on schedule with the right low ash oil.
- Use clean fuel and drain water from the separator.
- Keep DEF fresh and clean.
- Limit long idling.
- Fix coolant leaks and overheating at once.
Coaches and Buses
Many coach companies come to us for a Volvo D13 engine for sale. Prevost coaches and Volvo buses use the D13 with their own cooling, oil pan and accessory setups. A truck engine can often be used as the base, but parts like the oil pan, fan drive and mounts may need to come from your old engine. Tell us the coach model and year and we will confirm what you need.
Programming and Installation
The D13 is controlled by an engine computer that works with the vehicle and aftertreatment modules. When a replacement engine goes in, the software must match the vehicle. Injector codes need to be loaded, and settings like road speed, cruise and idle shutdown need to be set.
When your Volvo D13 engine for sale arrives, these steps help:
- Flush the cooling system and check the radiator.
- Clean the charge air cooler if the old engine failed with oil or metal in the intake.
- Check the DPF. One soaked in oil from a failed engine should be cleaned or replaced.
- Fit new filters, add fresh oil and prime the fuel system.
- Program the engine computer and clear old codes.

Rebuild Your Old D13 or Replace It?
An in-frame rebuild keeps your engine, but the truck sits during the work and hidden damage can raise the bill. A tested Volvo D13 engine for sale is usually quicker to fit, and you know its condition first. Your old engine may also have core value. If the block or crank is damaged, or the truck earns every day, replacement usually wins.
The Volvo Engine Brake
Many D13 engines carry the Volvo Engine Brake, often shortened to VEB. It works through the overhead and the exhaust to hold the truck back on long downhill grades, which saves the service brakes and keeps the truck under control. In hilly or mountain work it is one of the most useful features on the truck.
When you buy a Volvo D13 engine for sale, check whether the engine brake parts are fitted and working, and whether the switches and wiring in your cab match. The brake hardware sits on top of the engine, so it normally comes with a complete engine. We note its condition on every quote.
Like any moving part, the brake wears. Weak braking often comes down to valve lash, a tired control valve or a wiring fault. These are simple to fix, but it helps to know about them before the engine goes in.
Fuel Economy and Everyday Driving
Good fuel economy is one of the biggest reasons fleets like the D13. Paired with Volvo’s I-Shift automated gearbox, highway trucks often report figures from the mid sixes to above eight miles per gallon, depending on weight, speed, terrain and the generation of engine. The turbo compound versions tend to do best on long, steady runs.
Driving style still matters. The D13 makes strong torque low in the rev range, so letting the gearbox run at lower engine speeds saves fuel. Long idling burns fuel for nothing and loads up the particulate filter, so idle shutdown is worth keeping on.
A healthy Volvo D13 engine for sale should return economy close to what your old engine gave when it was in good shape. If yours had started using more fuel before it failed, worn injectors, a sticking turbo actuator or a clogged exhaust system may have been part of the cause, so check those parts during the swap.
Cooling System Care
Coolant problems end more engines early than almost anything else. On the D13, coolant also runs through the EGR cooler, so a weak cooling system puts extra stress on that part. Low additive levels can also let the liners and injector sleeves corrode over time.
The fix is routine maintenance. Use the correct coolant, test its strength and condition at every service, keep the radiator and charge air cooler clean, and replace hoses and the thermostat as they age. If you have just fitted a Volvo D13 engine for sale, start it off with fresh coolant and a properly flushed system.
A quick cooling checklist
- Test coolant strength and condition at every service
- Keep the radiator and charge air cooler fins clean
- Check the fan drive and thermostat
- Replace cracked or soft hoses
- Fix any coolant loss straight away
Buying for a Fleet
If you run several Volvo trucks or coaches, keeping a spare engine ready can save a lot of downtime. An engine swap is far faster than waiting on a long repair, and the vehicle is back earning quickly. We work with fleet buyers who need more than one Volvo D13 engine for sale and can help match engines to the different generations across your vehicles. Ask about multiple engine orders when you request your quote.

D13 vs DD15 and Other Engines
The D13 competes with the Detroit DD15 and the Cummins ISX15. It is a little smaller in displacement but very efficient, and it is the natural choice for any Volvo built around it. Changing brands means new mounts, wiring and software, so staying with a D13 is almost always the easiest path. Learn more about the maker on the Volvo Trucks page.
One more thing worth saying: a D13 that has been looked after is a very good engine, and good used ones hold their value. Buying from a seller who tests, photographs and describes the engine properly takes most of the risk out of the deal. Ask questions, get the details in writing and match the engine to your vehicle, and a used D13 can give you many more years of steady work.
Other Heavy Diesel Engines We Sell
We also supply the Detroit Diesel Series 60, the Caterpillar 3406E, the Cummins N14 and the Caterpillar C13. See all our used diesel truck engines.
