AR83.30-T-1209-01C | Inspect the refrigeration circuit for leaks. | ||
Danger! | Risk of explosion from welding or soldering work on closed air conditioning system. Risk of poisoning from inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant. | Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been discharged. |

WE58.40-Z-1002-20A | Air conditioning leak detector |
Leak test with full air conditioning system
1 Start vehicle engine.
2 Switch air conditioning on.
See air conditioning operating instructions.
3 Use the leak detector probe to check the entire air conditioning circuit.
4 Thoroughly examine locations where a leak is suspected.
Since the refrigerant is heavier than air and moves downward, always hold the probe of the leak detector below the suspected leak.
Defective pipe connections, screw-in pipe connections, condenser and evaporator are the most frequent sources of refrigerant leaks.
After repair work, always replace the filter drier.
