- Opens: coolant
Don't miss
- Risk of damage to condenser, refrigerant lines and refrigerant hoses.Do NOT stretch, kink or bend refrigerant lines and hoses. — Remove bolts (arrows) and secure condenser to prevent it dropping.
- Do not reuse coolant.
📋 Procedure
- ⚠ Hot steam/hot coolant can escape - risk of scalding.The cooling system is under pressure when the engine is hot.Cover filler cap on coolant expansion tank with a cloth and open carefully to dissipate pressure. — Open filler cap on coolant expansion tank.

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.
