Leak Test

WARNING: This page is about a different car, the 2020 Mazda CX-30. 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 there is gas leakage, tighten the piping connection to the specified torque, 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 TROUBLESHOOTING INDEX [FULL-AUTO AIR CONDITIONER] .) (See TROUBLESHOOTING INDEX [MANUAL AIR CONDITIONER] .)
Disconnect the quick couplers from the charging valves.
