Combustion Leak Detector tests for CO2 in cooling systems using a dual-chamber design for accuracy.
Tests for combustion leaks caused by a blown head gasket, cracked head or a warped sealing surface
Use on a liquid-cooled engine with a removable radiator or overflow cap
Tool with testing fluid (not included) tests if there are exhaust gases, (CO2), in the cooling system
Tester uses a dual-chamber, which eliminates false positives and provides a high-precision test
Easy to use - if the test liquid changes from blue to yellow or green, there is a combustion leak, indicating a damaged head gasket
