Installation advice (reconditioned) Engine
Correct installation of a remanufactured engine is essential for optimum performance and long service life. At EU Engines & Parts we give you expert and practical fitting advice, so that your engine not only fits perfectly, but also runs smoothly. Proper fitting prevents damage, power loss or excessive wear.
Why is built-in engine advice important?
A overhauled engine is technically like new, but that does not mean it can be put in any car without any points of attention. Components like the clutch, cooling and lubrication systems and engine suspension need to be in good condition or rechecked. Poor installation is one of the biggest causes of damage after overhaul.
That is why we provide clear installation advice with every overhauled engine, tailored to the engine type and vehicle. So you know exactly what to look out for.

Installation advice Engine
- Whether the engine supplied matches your engine.
- The delivered engine for any (transport) damage.
- Whether everything matches the agreements made.
- Check all oil seals for leaks. If in doubt, renew.
- Renew the gasket ring under the oil drain plug.
- Change oil and oil filter as per factory specifications.
- Pay attention to viscosity and quantity.
- Replace the complete distribution (possibly including the water pump).
- When you need to rebuild the intake manifold, make sure it is clean. (There are often metal particles in it from the broken engine that will cause the new engine to break down as well).
- Check the radiator for proper flow/leakage (after installation, check if the cooling oven motor starts).
- Avoid electronic failures. As far as possible, use electronic components such as wiring harness, sensors, temperature sensors, etc. that belong to the vehicle.
- Turbo engines: Ensure that enough oil reaches the turbocharger and that the oil can also flow away resistance-free (consider a kinked return line or the like). Make sure all intake tubes/hoses and intercooler are clean.
- On diesel engines with an immobiliser on the fuel pump, it needs to be converted. (The whole pump or just the immobiliser).
- Observe de- and assembly instructions according to factory data, tightening torques etc.
- After the test drive, check the oil level.
- After the test drive, check the engine for any leaks.
- Complete distribution.
- Head gasket (by arrangement).
- Leaks on water pump, hose gaskets and oil seals.
- Flywheel and clutch (pay particular attention to versions with a 2-mass flywheel)
- Consequential damage caused by supplied turbo and/or fuel pump
Important mounting points
- Cleaning the cooling system: Residues of dirt, rust or oil in the old cooling system can seriously damage the new engine. Thorough flushing is necessary.
- New oil & filters: Always use the correct engine oil and replace the oil filter and fuel filter when fitted.
- Checking auxiliary components: Think turbocharger, EGR valve, injectors and sensors. These can affect the engine if they are dirty or faulty.
- Catch up: Let the engine run in gently according to our instructions. Also read our special page on this subject: Running-in overhauled engines.
