Bolts marked with an "X" may not be used again.

Procedure

NOTE:

Replace the bolts which are being tightened with an additional turn.

Replace self-locking nuts and bolts and seals, gaskets and o-rings.

In vehicles with the multitronic transmission 0AW, there is a needle bearing in the drive plate. Check if the needle bearing is inserted before installing. Remove needle bearing from drive plate and install. Refer to NEEDLE BEARING IN DRIVE PLATE, REPLACING .

Secure all hose connections with hose clamps of the same type as those equipped by the factory.

In order to be able to securely mount the air guide hoses on their connectors, spray the screws on the previously used clamps with a rust remover.

When installing, bring all cable ties back to same positions.

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

-- When jointing the engine and subframe, hold the ATF lines in their installation position.

-- Clean the threaded holes in the cylinder block for connecting the engine and transmission using a thread tap before installing the transmission.

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