Installing engine - vehicles with four-wheel drive
Caution
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
Ensure that there is sufficient clearance to all moving or hot components.
Install in reverse order. In the process, note the following:
Check clutch release bearing for wear and renew if necessary.
Clean splines of input shaft and lightly grease them with
grease for clutch plate splines

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
