Advice: The engine crankcase protection must be made of metal at least 2.0 mm thick, otherwise it will not perform its function.
Depending on the design, the protection may differ in the way it is attached. As a rule, the protection is attached at the front with three nuts securing the engine mudguard, and at the rear with nuts securing the front suspension wishbone bolts.
To carry out the work you will need an inspection pit or overpass.
Sequence of execution
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. With a socket wrench by 19 mm unscrew the nut of the transverse arm mounting bolt (1), holding the bolt with a spanner of the same size. Similarly, unscrew the nut of the second arm (1). With a socket wrench by 10 mm unscrew the three central nuts (2) of the front engine mudguard mount.
