Kit contents:
PVC plastic tube
15ml reaction fluid
universal adapter: 25mm - 55mm
The tester is used to detect damage to the head gasket and cylinder head in liquid-cooled combustion engines (petrol, diesel, LPG).

Operating principle:
In the case of a damaged head gasket or cylinder head, some of the exhaust gases containing CO2, among others, enter the cooling system. The operating principle of the device is based on measuring the CO2 concentration - in the case of increased concentration, the reaction fluid reacts with CO2 and changes color.

How to use:
Fill the device with reaction fluid (approx. 2ml) to the level between the chambers.
Connect the tester to the opening of the expansion tank or radiator.
Start the engine (preferably already warm), increase the speed to obtain a higher combustion pressure.
Leave the engine at slightly increased speed and observe the behavior of the reaction fluid.
A change in the color of the reaction fluid to yellow or green within a few minutes of the test indicates a damaged head gasket or damage to the head itself.
After completing the tests, carefully dismantle the device.

Note. If the test is performed on the radiator filler neck, take extra care when unscrewing the cap and during the test itself - risk of scalding.

During the test, do not allow the coolant to mix with the reaction fluid. If the fluids mix, the test result may be incorrect.
