Cylinder head gasket tester XL 60 ml AMIO-02804

The tester is designed to eliminate suspicions of cylinder head gasket or head damage in liquid-cooled gasoline, diesel and LPG engines.

If the gasket is leaking and CO₂ enters the cooling system, the reaction fluid changes color to yellow or green.

The operating principle of the device is based on measuring CO₂ concentration - when the CO₂ content increases, the reaction liquid reacts and changes color.

The set includes:

• CO₂ reaction liquid 60 ml (enough for about 30 tests)
• Universal conical adapter 25-55 mm
• Measuring tube

Universal adapter
The black 25-55 mm measuring adapter allows you to test up to 6 times more different coolant fill hole diameters than testers with one standard white adapter.

Suitable for use:

• in passenger cars
• in trucks and tractors
• in construction equipment (excavators)
• on motorcycles
• in forklifts

The adapter is made of a special, high-temperature-resistant and sufficiently soft rubber compound, so it fits tightly to the filling opening and the tester tube, ensuring 100% tightness during testing.

Test instructions:

• Fill the tester with reaction liquid to the level between the chambers (approximately 2 ml).
• Connect the tester to the expansion tank or radiator opening.
• Start the engine and increase the rpm to achieve higher combustion pressure.
• Leave the engine running at slightly increased speed and observe the color of the reaction fluid.
• A color change to yellow or green within a few minutes indicates damage to the head gasket or the head itself.
• After completing the test, carefully remove the tester.

Interpretation of test results:

• Blue → green (diesel engine) – head gasket or head damage
• Blue → yellow (petrol / LPG) – head gasket or head damage
• Blue color unchanged – no CO₂ detected in the cooling system

Safety information:

• When performing the test on a hot engine, especially when unscrewing the radiator or tank cap, extreme caution is necessary - risk of burns.
• Do not allow the coolant to mix with the reaction fluid during the test, as this may distort the test result.
• Keep out of reach of children, wash hands thoroughly after testing.
