If you decide to remove the engine for repair, some preparations must be made.
The choice of the place where the work will be carried out is extremely important to ensure space for servicing and storing spare parts. It is advisable to do this at a bus station or in a garage with a level horizontal floor with a clean hard surface.
Before removing the engine, wash the engine and engine compartment. Removing the engine requires a lifting mechanism that allows you to safely lift the power unit.
If you are removing the engine for the first time, you should invite an experienced specialist. In addition, there are many cases where one person cannot simultaneously perform all the actions when removing the engine.
