The use of ACDelco Coolant System Tracer Dye will not change the original appearance of the long life coolants. This tracer dye is used in conjunction with ACDelco Ultra Violet (UV) Leak Detection Lamp Kit (PN 12377979).

Pros: I thought I was ordering 1 bottle. An entire box of 5 was delivered. I guess it was more hassle to break up the box into smaller orders? The dye worked just fine.Cons: None.

My parents Buick enclave had a coolant smell when parked or waiting at red lights. They brought the car over to me and I couldn’t really pinpoint the leak being that there was minimal spray in the engine bay and low leaks on the ground. Used this product because the ones they sold at auto zone and advanced auto said they couldn’t be used with dexcool coolant. Worked great and was able to find tiny crack in radiator (with a uv light I bought off Amazon) no problem.

Even after losing and replacing much of my coolant, which caused the dye to become diluted, it was still bright enough to help me spot water coming out the weep hole in the bottom of my water pump.

I poured the entire bottle into the reservoir on my 07 LBZ. After driving about 100 miles I shined a UV light under hood and found the leak within maybe 5 minutes. I'm actually buying another bottle right now for my Yukon.

Poured 1/2 bottle into the coolant tank of my 02 Yukon. After a short drive, I did an inspection of my cooling system and engine, and a crack on my water pump showed up under my uv light. Worked gereat!
