Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine, Installing
Tightening specifications, refer to TIGHTENING SPECIFICATIONS .
Installation is performed in the reverse order of removal. When doing this note the following:
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.
- To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.
Vehicles with a Manual Transmission:
-- Grease the splines of the input shaft lightly using grease for clutch plate splines G 000 100.
-- Check and install the clutch and clutch mechanism. Refer to [For transmission(s) 0A4] Removal and Installation .
Continuation for all Vehicles:
-- First, firmly secure the engine mount to the engine, then align the engine/transmission free of tension via a shaking motion and tighten the engine/transmission mount bolts.
