CAUTION
Risk of freezing injury caused by escaping pressurised refrigerant.
There is a risk of injury to the skin and parts of the body due to freezing.
Always wear safety gloves.
Always wear safety goggles.
If, when detaching the pressure sender, refrigerant escapes from the refrigerant line for longer then 1 second, tighten the pressure sender, and renew the non-return valve which is defective.
Extract refrigerant, and open the refrigerant circuit immediately afterwards.
If more than 10 minutes passed since the refrigerant has been extracted, do not open the refrigerant circuit prior to extracting refrigerant anew. Due to re-evaporation, pressure will be built up in the refrigerant circuit.
CAUTION
Risk of freezing injury caused by escaping pressurised refrigerant. If handled improperly, the union may be torn off letting the refrigerant escape.
There is a risk of injury to the skin and parts of the body due to freezing.
Always wear safety gloves.
Always wear safety goggles.
Counterhold refrigerant line using a suitable tool.

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.
