Ask any old Mercedes mechanic which petrol V8 they trust most and a lot of them will point at the M113. It is not the newest or the fanciest engine, but it just keeps going. So when one finally does give up, after a cooling fault, a neglected oil change or a cracked block in a cold winter, most owners do not want a different car. They want a Mercedes M113 engine for sale that goes straight back in.
That is what we supply. We sell tested, fairly used M113 V8 engines and ship them to private owners, workshops and importers worldwide. You get photos of the real engine, a written quote, a warranty and a fit check against your car before any money changes hands.

What Is the Mercedes M113?
The Mercedes-Benz M113 is a 90 degree V8 petrol engine that Mercedes introduced in 1997 to replace the older M119. It shares a lot of its design with the M112 V6, which came out at the same time. Standard engines were built in Germany at Untertürkheim, while the AMG versions were put together by hand at Affalterbach.
Mercedes kept the design fairly simple. Each bank has a single overhead camshaft driving three valves per cylinder, two intake and one exhaust, and every cylinder has two spark plugs. The block is aluminium with silicon-aluminium cylinder walls, so there are no separate liners to wear. The result was a light, smooth and very durable V8 that sat in everything from the E-Class to the G-Class.
It was replaced by the M273 from 2005 and by the M156 and M152 in AMG cars, but the M113 stayed in the G500 for years after that. With so many cars still on the road, a Mercedes M113 engine for sale is one of the steadiest requests we get from Mercedes owners.
Mercedes M113 Engine Specifications
The M113 came in three sizes plus a supercharged AMG version. We always check the full engine number before we quote a Mercedes M113 engine for sale, because the sizes are not interchangeable without changes.
| Layout | 90 degree V8, SOHC per bank, 3 valves per cylinder, 2 spark plugs per cylinder |
| Block and heads | Aluminium, silicon-aluminium cylinder bores |
| M113 E43 | 4,266 cc, 89.9 x 84.1 mm, about 275 to 279 hp, 400 Nm |
| M113 E50 | 4,966 cc, 97.0 x 84.0 mm, about 302 to 306 hp, 460 Nm |

7 Proven Tips Before You Buy a Mercedes M113 Engine for Sale
1. Get the full engine number
The first part tells you the type, such as 113.960 or 113.962. It is stamped on the block. Without it, you are guessing.
2. Ask for a compression test
Eight even readings mean healthy rings and valves. A low cylinder needs an explanation.
3. Look at the oil
Clean oil with no sludge, no milkiness and no metal. Sludge on an M113 usually means long oil change intervals.
4. Check for oil leaks
Valve covers, the crankcase breather area and the oil pan are the usual spots. Small leaks are normal, big ones should be noted.
5. Check the harmonic balancer
The rubber ring in the crank pulley can split with age. A wobbling pulley is a warning sign.
6. Know what comes with it
Intake manifold, wiring, starter, alternator, supercharger on AMG engines? Ask for a written list.
7. Get the warranty in writing
Read the terms before you pay. Our used engine warranty page explains what we cover.
Common Mercedes M113 Problems
The M113 is famous for being tough, but age catches up with every engine. These are the things we look at before we offer a Mercedes M113 engine for sale.
Crankcase breather hoses
The plastic and rubber breather hoses go hard and crack, or the system blocks up. Pressure builds in the crankcase and oil starts to leak from gaskets and seals. Replacing the breather parts is cheap and fixes a lot of leaks.
Valve cover gaskets and spark plug tube seals
Oil can seep into the spark plug wells and onto the coils. You get misfires and a burning oil smell. New gaskets sort it out.
Harmonic balancer
The crank pulley has a rubber layer that can separate on older engines. If it lets go, the outer ring can damage belts and the front of the engine.
Engine mounts
The hydraulic mounts wear out and the engine starts to shake at idle. Fit new mounts with the new engine.
Sensors
Camshaft and crankshaft position sensors and the mass air flow sensor can fail with age, causing hard starts, stalling or poor running.
Supercharger parts on AMG engines
On the M113K, the supercharger pulley isolator and the intercooler water pump are the parts that wear out. A weak intercooler pump means hot intake air and lost power.
Overheating
Like any aluminium V8, the M113 does not forgive a cooling failure. Many engines we replace died from a split hose, a failed fan or a radiator that let go on a hot day.
None of this makes the M113 a weak engine. It just means you want a seller who looks closely instead of shipping it blind.
How We Test Each Mercedes M113 Engine for Sale
- We record the engine number, size and donor car where we have it.
- We run a compression test on all eight cylinders.
- We check the oil and coolant for contamination and sludge.
- We look at the harmonic balancer, breather system and gaskets.
- We check the timing chain area for noise and wear where we can.
- We check the supercharger for play and noise on AMG engines.
- We photograph the engine from every side and send the photos to you.
- We drain, cap and pack the engine for transport.
You see the real engine before you pay. If you want another photo of a Mercedes M113 engine for sale, just ask and we will take it.
M113 vs M273: Which One Do You Need?
The M273 replaced the M113 in many cars from about 2005. It has twin overhead cams per bank, four valves per cylinder and variable valve timing. It makes more power, but it is a completely different engine and it does not fit an M113 car without major work.
If your car came with an M273, see our Mercedes M273 engine for sale page instead. If you are working on a V6 model of the same era, the Mercedes M272 engine is the matching six-cylinder. The simple rule is to replace like with like. If your car left the factory with one, a Mercedes M113 engine for sale is the right fix.
Repair or Replace?
Most M113 leaks and sensor faults are cheap repairs. But some problems make a replacement the better choice:
- A knock from the bottom end, often from a spun bearing after low oil.
- Coolant in the oil after overheating.
- A cracked block, which happens in cold countries when the antifreeze was weak.
- Low compression across several cylinders.
- Heavy sludge damage after years of skipped oil changes.
Send us the symptoms and any workshop report. We will tell you honestly if a Mercedes M113 engine for sale is worth it for your car.
Used, Rebuilt or Remanufactured?
Fairly used engines come from running cars, are tested and are sold in good condition. They are the cheapest and quickest option.
Rebuilt engines are stripped and fitted with new bearings, rings and gaskets. They cost more and take longer.
Remanufactured engines are built to a set standard and cost the most. Our guide to remanufactured vs rebuilt engines explains the difference.
The M113 is so tough that a good used engine is usually the best value. A clean used Mercedes M113 engine for sale with known history often outlasts a cheap rebuild.
Long Block or Complete Engine?
A long block includes the block, crank, pistons, heads, cams and timing chain. It suits you if you want to keep your own intake, sensors and accessories.
A complete engine comes with the intake manifold, fuel rails, injectors, wiring and many bolt-on parts. On AMG engines it can include the supercharger. Each quote for a Mercedes M113 engine for sale says exactly what is included.
What a Mercedes M113 Engine for Sale Costs
Price depends on the engine itself. These are the main factors:
- Size: 4.3, 5.0, 5.5 or supercharged 5.5
- Mileage and condition
- Long block or complete engine
- Included parts, such as the intake or supercharger
- Shipping method and destination
Tell us your engine number and we will price the matching Mercedes M113 engine for sale with shipping. Our article on replacement engine cost explains the other costs to plan for.
Notes for G500 and ML Owners
A lot of M113 engines we ship go into G-Wagens and ML SUVs. These vehicles work hard, often off road, in heat and dust, and sometimes with heavy loads or trailers. Their engines use different sumps, pickups and mounts from the saloons.
When you replace an engine in a G500 or ML500, check the radiator, fan clutch or electric fan, transmission cooler and all coolant hoses. A tired cooling system is the most common reason these engines fail. Send us your chassis number and we will find the correct Mercedes M113 engine for sale for your SUV.
Notes for AMG Owners
AMG M113 engines carry a signed plaque from the engineer who built them. Collectors often want to keep the original plaque or ask for a matching engine. Tell us if originality matters to you. For supercharged cars, check the intercooler pump, the heat exchanger and the supercharger drive before you fit the new engine. A healthy cooling circuit keeps a supercharged Mercedes M113 engine for sale making full power for a long time.
Worldwide Shipping
We ship to Europe, Africa, the Middle East, Asia, Australia and the Pacific, the Caribbean, and North, Central and South America. Sea freight costs less and suits most buyers. Air freight is quicker when time matters.

Installation Tips
- Find out why the old engine failed and fix that first.
- Replace the radiator, hoses and thermostat if the old engine overheated.
- Fit new breather hoses, valve cover gaskets and spark plug tube seals while you have access.

Do this and your Mercedes M113 engine for sale from us will give you many years of easy driving.
When the Engine Arrives
- Photograph the crate before opening it.
- Match the engine number to your quote.
- Check every listed part is there.
- Turn the engine over by hand.
- Contact us within the time stated on the quote if anything is wrong.
Looking After Your M113
The M113 does not ask for much, but it does ask for the basics. Change the oil and filter on time with the grade Mercedes lists, and do it a little sooner if you live somewhere hot or spend a lot of time in traffic. Sludge is the slow killer of these engines, and almost every sludged engine we see came from a car that went too long between services.
Keep the cooling system in good shape. Replace old hoses before they split, check the fan works, and use the right coolant mix. Aluminium V8s hate running hot, and one overheat can undo years of careful driving. Clean the breather system every so often and replace the spark plugs on schedule. With that kind of care, a Mercedes M113 engine for sale from us can run for a very long time.
Fuel Quality and the M113
One of the reasons buyers in so many countries like this engine is that it is not fussy about fuel. With port injection and a modest compression ratio, the standard 4.3 and 5.0 engines run happily on ordinary premium petrol. The supercharged AMG version wants the best fuel you can get, but even then it is more forgiving than many modern direct injection engines. If you live where fuel quality changes from one station to the next, a naturally aspirated Mercedes M113 engine for sale is a sensible and low stress choice.
Notes for Workshops and Importers
If you run a Mercedes workshop or import engines, we can quote several units together and ship them in one load to cut freight costs. Many trade buyers pair a Mercedes M113 engine for sale with M272 and M273 units in the same shipment, since all three are common in the same markets. We send photos and test notes for each engine, so you can share them with your own customers. Tell us which engine numbers you see most and we will look out for them.
