Test Procedure: Notes
WARNING: This page is about a different car, the 1999 GMC Sierra and 1999 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Take care to prevent personal injury which could occur due to touching a hot engine when testing. Tests should be done with the engine "Off" and as cool as possible. Do not operate the detector in a combustible atmosphere since its sensor operates at high temperature.
IMPORTANT:
Always follow the refrigerant system in a continuous path, so that no areas of potential leaks are missed. Always test all of the areas listed below in order to make sure the entire system is leak-free, even when one leak is already found.
Use this procedure in order to test the following components and locations in the system:
- The evaporator inlet and outlet
- The accumulator inlet and outlet
- The condenser inlet and outlet
- All of the brazed and welded areas
- The areas showing signs of damage
- The hose couplings
- The compressor rear head
- The housing joints
