Head Gasket Tester Combustion Leak Test Kit with 8.5Oz Testing Fluid 

• Dual chamber Design: Our cylinder head gasket combustion leak tester adopts a unique dual chamber structure, filtering water vapor and alkaline particles through the lower chamber, allowing only pure gas to enter the detection area of ​​the upper chamber, effectively preventing the test fluid from being contaminated, improving detection accuracy and the number of repeated uses
• Wide Compatibility: The universal handheld conical adapter equipped with our head gasket leak tester kit has a wide measurement range (17-45 mm), which is suitable for handheld detection of coolant reservoir or radiator ports of most gasoline and diesel engines; It also supports inserting the lower chamber of the tester into the brass adapter (not included in the package) for a more stable connection
• Easy to Use: First pour the test fluid into the upper chamber of the head gasket tester to the dotted line mark, then screw the adapter into the radiator port (wear thick gloves to hold the press tester to ensure that there is no leakage), start the engine at idle speed, press the top rubber bulb several times, and observe the color change of the test fluid
• Color changing Test Fluid: During the test, if the CO2 test fluid does not change color, the cylinder head gasket is not leaking; If the fluid changes color to yellow or green, it means that the cooling system detects combustion gas and further inspection is required for cylinder head gasket leakage or cylinder head damage
