Leak trace using the UV lamp
The fluorescent tracing agent is green when leak tracing with a UV lamp.

NOTE: This light green color may be mistaken for leaked or spilled coolant which Volvo uses in its products. The method for leak tracing using fluorescent tracing agent is the same for both factory filled and aftermarket filled climate control systems.
