About this product
A combustion leakage tester kit used to check for exhaust gases in the radiator coolant system, helping identify possible head gasket damage as well as cracked or warped cylinders. This 7-piece set is intended for fault finding on petrol, diesel and gas powered vehicles where early diagnosis can save time before larger repair work begins.
Used for vehicle servicing, garage work and engine diagnostics, this kit helps when a car, van or light vehicle is showing symptoms that may point to combustion gases entering the cooling system. It is useful for mechanics, workshops and capable home users carrying out head gasket checks, investigating coolant issues or confirming whether further strip-down work is likely to be needed. The colour-change test process helps with identifying very small amounts of carbon dioxide in coolant, making it a practical option when tracking down hard-to-confirm engine faults.
The kit includes a tester with conical adapter, a test fluid bottle and a quick release adapter for direct connection to radiator adapters. It works in combination with combustion leak detector fluid, which is not included, and the test liquid changes colour from blue to green to yellow during use. Compatibility is stated for use with sets CT1585 and CT3380. For regular diagnostic work, the included adapters help keep the testing process straightforward and reduce guesswork when checking common cooling system fault symptoms.
