This is a Mercedes M113 engine for sale in fairly used condition: a complete V8 petrol engine, removed from a running vehicle, checked, tested and ready to ship anywhere in the world. The M113 powered a huge range of Mercedes models from 1997 to about 2011, from the E500 and S500 to the ML500 and G500, and it is still one of the most trusted V8s the brand ever built.
We match the engine number to your vehicle and send you photos of the actual engine before you pay. You know exactly what is coming.

M113 Sizes Explained
4.3 litre. Smooth and relatively economical, used in the 430 models.
5.0 litre. The most common size, used in nearly every 500 model. This is the Mercedes M113 engine for sale most buyers need.
5.5 litre AMG. Hand built by AMG with a longer stroke and stronger internals.
5.5 supercharged AMG. The Kompressor engine with a supercharger between the banks and a water cooled intercooler. Quoted separately because of its special parts.
Some S500 and CL500 engines also had cylinder cut-off, which uses different valve gear. We always state the exact engine number on your quote.
Condition: What Fairly Used Means
Fairly used means the engine came out of a vehicle that was running, not from a fire or flood. It has normal wear for its age and mileage, it is not rebuilt, and it is priced as a used engine. Any small issues we find, like a weeping gasket or a cracked plastic cover, go in your notes so the Mercedes M113 engine for sale you receive matches what you were told.
How We Check Each Mercedes M113 Engine for Sale
- Record the engine number, size, mileage and donor vehicle where known
- Compression test on all eight cylinders
- Inspect oil and coolant for contamination and sludge
- Check the harmonic balancer rubber for splitting
- Check breather hoses and gaskets for leaks
- Listen for timing chain noise where possible
- Check supercharger play and noise on AMG engines
- Photograph the engine from every side
- Drain, cap and pack for transport
Known M113 Weak Points
- Crankcase breather hoses. Crack or block with age, causing oil leaks. Replace them during the swap.
- Valve cover gaskets and plug tube seals. Oil in the plug wells causes misfires.
- Harmonic balancer. The rubber layer can separate on old engines.
- Engine mounts. Hydraulic mounts wear and cause vibration.
- Sensors. Cam, crank and MAF sensors can fail with age.
- Supercharger parts. Pulley isolator and intercooler pump on AMG engines.
None of these stop the M113 being a tough engine. They are just what a sensible buyer of a Mercedes M113 engine for sale should plan for.
Price and What Affects It
The price shown is for a complete, fairly used 5.0 litre engine. The final price can change with:
- Size: 4.3, 5.0, 5.5 or supercharged 5.5
- Mileage
- Complete engine or long block
- Included parts such as the intake or supercharger
- Shipping method and destination
Your quote lists the engine, parts and freight separately. Our guide to replacement engine cost helps you budget for fitting.
Complete Engine or Long Block?
A complete engine comes with the intake, rails, injectors and most bolt-on parts and is quickest to fit. A long block is the core only: block, crank, pistons, heads, cams and chain. A long block Mercedes M113 engine for sale costs less and suits you if your own intake and sensors are healthy.
Used, Rebuilt or Remanufactured?
This listing is for a fairly used engine, the quickest and cheapest option. Rebuilt and remanufactured engines cost more. Our guide to remanufactured vs rebuilt engines explains the difference. The M113 is so durable that a tested used Mercedes M113 engine for sale often outlasts a cheap rebuild.
Notes for G500 and ML Owners
Many of our M113 engines go into G-Wagens and ML SUVs that work hard in heat, dust and off road. Before fitting the new engine, check the radiator, fan, transmission cooler and every coolant hose. A tired cooling system is the most common reason these engines fail. Send your chassis number and we will match the right Mercedes M113 engine for sale for your SUV.
Notes for AMG Owners
AMG engines carry a plaque signed by the engineer who built them. If originality matters to you, tell us and we will look for a suitable unit. On supercharged cars, check the intercooler pump and heat exchanger before you fit the engine, so it makes full power from day one.
Fitting Advice
- Find out why the old engine failed and fix the cause.
- Replace the radiator, hoses and thermostat if the old engine overheated.
- Fit new breather hoses, valve cover gaskets and plug tube seals.
- Fit new engine mounts.
- Check the harmonic balancer.
- Use the Mercedes approved oil grade and change it early.
Looking After Your New Engine
Change the oil on time, a little sooner in hot countries or heavy traffic. Keep the cooling system healthy, clean the breather system now and then, and replace spark plugs on schedule. With that basic care a Mercedes M113 engine for sale from us can run for many years. Because the 4.3 and 5.0 litre engines use port injection and a modest compression ratio, they are also forgiving of ordinary premium fuel, which helps in places where fuel quality varies.
Notes for Workshops and Importers
We can quote several engines at once and ship them together to save on freight. Many trade buyers pair a Mercedes M113 engine for sale with M272 and M273 units, since they are common in the same markets. Every engine is labelled with its number and quote reference, with photos and test notes for your customers.
Matching the Engine to Your Vehicle
Send us your VIN and a photo of the engine number on your old block if you can. We check the model, year and engine type, then confirm the Mercedes M113 engine for sale in writing before you pay. If we do not have a true match, we say so.
Why Replace Like for Like
From 2005 Mercedes began replacing the M113 with the M273, a four-valve V8 with variable valve timing. It makes more power, but the mounts, wiring, engine computer and many sensors are different, and it will not drop into an M113 vehicle without serious work. The same goes for AMG engines such as the M156. If your car left the factory with an M113, a Mercedes M113 engine for sale of the same size is the simplest and cheapest way back on the road. It bolts into the same mounts, plugs into the same harness and runs on the same software.
Signs a Replacement Makes Sense
Most M113 problems are repairs: leaks, mounts and sensors. A replacement engine becomes the better value when you have:
- A knock from the bottom end after running low on oil.
- Coolant in the oil after an overheat.
- A cracked block, often from weak antifreeze in a cold winter.
- Low compression on several cylinders.
- Heavy sludge damage from years of missed oil changes.
Send us the symptoms or a workshop report and we will tell you honestly whether a Mercedes M113 engine for sale is the right move.
What Your Workshop Will Need
Any experienced Mercedes mechanic knows this engine well. Plan for fresh coolant, the correct oil, new engine mounts and new gaskets for any parts moved across from the old engine. Ask your workshop to move sensors and brackets carefully and check the harness plugs for oil. On G-Class and ML models, check the transfer case and front axle seals while the engine is out. With those basics covered, fitting a Mercedes M113 engine for sale is a routine job that usually takes a day or two of workshop time.
