Find an A/C leak with an AC leak detection kit
If you’ve recharged the A/C in your car and it’s now blowing warm air, you’re probably wondering how to find A/C leak. Pros use two methods: an electronic leak detector and an AC leak detection kit with dye.
To find A/C leak with dye you must inject into the system in one of two ways: when the system is empty, or using an injector tool. The injector tool

screws onto a charging port and forces the dye into the system when it already has a refrigerant charge. After injecting the dye, operate the vehicle for several days to allow the dye to escape near the leak. Then use a black light to spot the glow emitted from the dye.
I’ve used both methods to find A/C leak. An electronic A/C leak detector can be fooled if you’ve used any spray cleaners recently. However, A/C leak detection dyes are pretty foolproof. If your black light spots a leak, it’s not lying.
