Fluorescent Leak Detector

Tool Required:

J-36790 Fluorescent Leak Detection Additive for R-12 systems only.

A leak detection additive is sometimes useful when trying to find a leak that may only become apparent with the natural vibrations and temperature/pressure relationships of a running vehicle. This type of leak detection is only practical for locating large leaks that are accessible visually under an ultraviolet light. No fluorescent detection additive is currently approved by GM for use in R-134a systems.
