Description
A combustion leak tester is an essential diagnostic tool for detecting leaks between the combustion chamber and the cooling system - most commonly caused by blown cylinder head gaskets, cracked cylinder heads, or warped engine blocks.
By analysing the gases in the cooling system, it identifies the presence of exhaust gases where they shouldn’t be, giving a fast, reliable indication of engine health.
Typical uses include:
- Verifying suspected head gasket failure.
- Checking for cracks in cylinder heads or engine blocks.
- Confirming internal coolant leaks before costly repairs.
This test can save hours of troubleshooting time, reduce guesswork, and prevent unnecessary part replacement.
Key Features of the XL Model
-
Fast & Accurate Diagnosis – Quickly confirms combustion leaks without dismantling the engine.
-
XL Chamber for Improved Testing – Larger test chamber allows for more accurate gas sampling.
-
Quick-Connect Adapter – Compatible with models 33140000 and 331400V2 for easy integration into existing setups.

How It Works
-
Fill the tester with reaction fluid (standard or sensitive, depending on the test requirement).
-
Connect to the radiator or expansion tank using the included quick-fit adapter.
-
Run the engine - combustion gases, if present, will pass through the chamber.
-
Watch for a colour change in the reaction fluid, indicating the presence of exhaust gases.
