Leak Down Test Using Compression Tester (Cheat Code/ Tips & Tricks)

This is a quick little tip if you don’t have the correct gauges to perform a leak down test. This is an alternative if you just want to know where the air is escaping from and only have a compression tester. This was performed with a compression tester rented from AutoZone along with an A/C Valve Core Repair kit I purchased for a few bucks.
