Procedure

NOTE:

Replace the bolts that were tightened with an additional turn.

Replace the self-locking nuts and bolts, as well as the seals, gaskets and O-rings.

The hose connections as well as air duct pipes and hoses must be free of oil and grease before installing.

Secure all hose connections with hose clamps that match the ones used in series production. Refer to the Parts Information.

During installation, install all cable ties back at the same position.

-- Install the engine support and engine mount. Refer to OVERVIEW - SUBFRAME MOUNT .

-- The following preparations must be made before connecting the engine and transmission:
