Attention:
- Use protective gloves during work.
- To avoid refrigerant leaks from the air conditioning system, be careful not to damage the pipes (do not deform, twist, etc.). To prevent atmospheric moisture from entering the air conditioning system, it is necessary to seal all openings in the refrigerant circuit in a timely manner.

Installation of the power unit
Attention:
- To prevent leaks, make sure that the gasket and the contact surfaces of the pipes are in good condition. The contact surfaces must be clean and free of scratches.
- Plugs should be removed from any component openings immediately before the component is installed. In addition, new parts should be removed from their packaging immediately before installation.
Installation is carried out in the reverse order of removal, observing the required tightening torques
Fill the power steering circuit.
Fill and bleed the engine cooling system.
Fill the gearbox with transmission oil.
If necessary, add engine oil.
Using a special station, fill the air conditioning system.
Check for leaks in various systems.
Tightening torques for threaded connections
| Threaded connections | Tightening torque |
