Find and Locate Internal Combustion Leaks
Instruction:
For use on gasoline engines only – not recommended for Diesel.
Remove radiator cap and check coolant level. Siphon or drain coolant until level is 2 or 3 inches below opening (A higher level will permit coolant to be drawn into Leak Check, contaminating the test fluid).
Fill Leak Check with fluid to line.
With engine warm and idling, push rubber cone into radiator opening and hold.
Squeeze and release aspirator (black) bulb for 2 minutes (unless test fluid YELLOW sooner). This action draws air from cooling system and forces it through the test fluid. IF COMBUSTION GASES ARE PRESENT IN THE COOLING SYSTEM – as a result of a cracked head, cracked block or a leaking cylinder head gasket, the test fluid will CHANGE from a BLUE or Blue Green to a YELLOW color.
