Severe damage often occurs following an engine repair. Faults that are not resolved in the periphery of the engine, whether mechanical or electrical, can lead to costly consequential faults. With the following checklist, the majority of possible sources of trouble can be eliminated during engine installation.
There may still be fragments, metal chips or other soiling in the intake system from engine damage.
Charge air cooler
Following engine damage, there are often large quantities of engine oil in the charge air cooler.
Supply and return lines are blocked with carbon due to thermal influences, the resulting inadequate oil
The turbine and compressor impellers must be in impeccable condition, they must not be deformed or
Oil filter, oil cooler and
Metal chips resulting from engine damage can be flushed to the clean side of the oil filter. Thoroughly
After you have connected it to all components supplied with pressure oil (oil cooler, turbocharger,
As a result of engine damage, fragments of pistons, valves and the turbocharger, as well as fuel and oil,

Injectors and high-pressure pumps in diesel engines are extremely sensitive to fuel contamination.
Filling the tank with the incorrect fuel frequently leads to engine damage. If there is any uncertainty
Before installing the engine, rinse cooling system components remaining in the vehicle with clean water.
Only use specified coolant agent in the correct dilution. Do not start up the engine, even briefly, without
Check correct connections using a circuit diagram of all vacuum lines and electrical plug-in connections.
Before starting up the engine, oil pressure must be built up. If necessary, take suitable action to ensure
After start-up, do not damage the engine through repeated early acceleration. The oil system needs some

Read out the fault code memory, note the diagnostic trouble codes and then delete the fault code
Engine electronics with
The actuator test is used to check the function of the relevant components.
Adapt, teach in
Today, many components have to be adapted following replacement. These include, for example:
Common rail injectors
After being swapped or replaced, common rail injectors must be programmed in the control unit
The test run should incorporate a cold start, warm-up, urban traffic, driving on a highway and a
Fault code memory
Always check and delete the fault code memory before and after the test run, even if the MIL (malfunction
