What is AC system dye?
It’s a method in which a small amount of fluorescent dye is injected into and circulated through an operating system. The dye/refrigerant mixture will escape and accumulate at all leak sites. By then scanning the system with a leak detection lamp, all leaks will fluoresce green or yellow, making them easy to spot.
What is AC dye used for?

How to add UV dye to a / C system?
Either pour some in the hose as you described . Or stick the end of the hose in some oil ( containing dye ) and open the manifold low pressure valve enough to let it slurp up the dye / oil . To be safe , after it has ” digested ” the oil / dye , vacuum it down again . A pain , I know . But you asked …….
How does dye based Freon leak down test work?
Definition: A dye based air conditioning leak-down test uses a colored dye to find freon leaks in your air conditioning system. Using this test, a colored dye is injected into the a/c system which will be visible under UV (ultra-violet) light at the point of a leak anywhere in the system.
How to inject the dye into the air conditioner?
1 Follow the air conditioning hoses to the low side air conditioning fitting. Unscrew the cap. 2 Attach the tube that is connected to the dye canister to the Schrader valve that was exposed when you unscrewed the “L” cap. 3 Unscrew the bottom of the dye canister to allow dye to flow into the system.

In order to repair the air conditioner, you will need to find the leak by injecting ultraviolet dye into your AC system. Follow the air conditioning hoses to the low side air conditioning fitting. Unscrew the cap.
How to add fluorescent dye to a / C system?
Fluorescent dye worked better with a little oil to get it into system. Charge system and run for awhile, then check with “Black light”. You can inject the oil/dye under pressure (don’t need a vacuum) from your 134a supply connected to the injector.
