NOTE: THIS BULLETIN APPLIES TO VEHICLES USING R-134A REFRIGERANT IN THE A/C SYSTEM.

EQUIPMENT REQUIRED

Tool No.	Description
BG-750	PSE 12 Volt UV Lamp (or equivelant)
BG-734	PSE R-134a Dye Injector (or equivelant)
BG-795	PSE Brite-Out(R) Fluorescent Dye Cleaner (or equivelant)
BG-71224	PSE R-134a Stay Brite(R) Fluorescent Leak Dye (or equivelant)

DISCUSSION

Vehicles from the factory no longer have leak detection dye in the A/C system. To determine the source of the R-134a leak.

Add dye to the system. Using BSL-734 R-134a Dye Injector (or equivalent) add 7.39 ml (0.25 oz.) of BSL-172 leak tracer dye through the A/C system low pressure service port.
NOTE: THE DYE INJECTOR HOLDS EXACTLY 7.39 ML (0.25 oz) OF LEAK TRACER DYE.
Clean dye from surfaces. Any spilled dye should be cleaned from surfaces using BG-795 Fluorescent Dye Cleaner (or equivalent).
NOTE: ANY DYE ON THE EXTERIOR OF THE A/C COMPONENTS MAY BE DIAGNOSED AS A LEAK.
Operate the system. This will thoroughly mix the dye with the system lubricant. The operating time needed for the dye/lubricant to penetrate the leak(s) will depend on the size of the leak(s). A very small leak will take from hours to days of system operation to appear.
Check for leak(s). Using a BF-450 12 volt UV Lamp (or equivalent), scan all lines, fittings, and components. The exact location of the leak(s) will be pinpointed by a bright yellow/green glow of dye. When checking for evaporator leak(s) shine the UV light at the evaporator drain hole to check for traces of dye. If traces of dye appear at the drain hole, check the evaporator and connections when the unit is removed from the vehicle. Verify leak location.
Install identification sticker. Place one of the dye ID stickers (included with dye) in a prominent location showing that the vehicle has a fluorescent dye in the A/C system that can be used to detect future leaks. The dye will not affect the operation or durability of the A/C system.
