Procedure

Replace the bolts that were tightened with an additional turn after removing them.
Replace the self-locking nuts and bolts, gaskets, seals and O-rings after removing.
Only remove the plugs or caps just before installing the respective lines.
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.
Check the vacuum hoses for damage before the assembly and replace if necessary.
During installation, all cable ties must be installed at the same location.
Bonded rubber bushings have a limited range of rotation. Only tighten suspension threaded connections when vehicle is in curb weight position or in the control position.

-- Bring the starter into the installation position.

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

Secure the engine with the subframe on the :VAS6131B .
