Description

Fast, economical and accurate method to test for combustion gas leaks

Works on Petrol, Diesel and LPG engines

Sure diagnosis within a few minutes

Positive proof that a leak is present when the tester fluid changes colour on detection of CO₂ gas - if there is a hairline crack in the cylinder head, engine block or damage to the cylinder head gasket, the test fluid turns yellow. 

Ideal for routine checks and scheduled maintenance work

Ideal for engine checks on used cars

Specifications:

Volume:  30ml

Color: clear

Type: Head Gasket & Block Tester

How does it work?

In the case of a damaged gasket under the head or the head itself, part of the combustion gases containing CO₂ goes to the cooling system, at this point they react with the liquid and change its colour. 

Performing the test:

1.    Fill the device with reaction fluid to the level just below the chambers (approx. 2ml), as shown in the photo below.

2.    Connect the tester to the opening of the expansion tank or radiator.

3.  Start the engine (preferably already warm), bring it to a higher speed to obtain a higher combustion pressure.

4.  Let the engine run at a slightly increased speed and observe the behaviour of the reaction fluid (it should be moving and allowing bubbles of air through).

5.   Changing the colour of the reaction fluid to yellow or green within a few minutes indicates a damaged gasket under the head or damage to the head itself. Do not perform the test for longer than 5 minutes, as heat is harmful to the reaction fluid.

6.    After the test has been completed, carefully remove the device. The used test fluid should be disposed of, even if the test result was negative. We would never recommend using any combustion leak detector fluid twice, as this may affect the accuracy of the test.
