Leak Test
WARNING: This page is about a different car, the 2018 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- Looking directly at a fluorescent agent-detecting UV black light may cause injury to the eyes. Do not look directly into the light of a fluorescent agent-detecting UV black light.
NOTE:
- Because fluorescent agents (yellow or light green dye) are in the refrigeration cycle, the leak test can be performed with a fluorescent agent-detecting UV black light.
- Inspect for gas leakage from the piping connection using a gas leak detector or a fluorescent agent- detecting UV black light.
- If there is no leakage, go to Step 3.
- If leakage is found at a loose joint, tighten the joint, then go to the next step.
- Inspect for leakage again.
- If there is no refrigerant leakage, perform the procedure from the evacuation again. (See EVACUATION .)
- If there is refrigerant leakage, inspect the refrigeration system following the symptom troubleshooting procedure. (See FOREWORD [CLIMATE CONTROL SYSTEM] .)
- Disconnect the quick couplers from the charging valves.
- Install the caps to the charging valves.
