When fluid turns from blue to yellow a combustion leak is present. The kit is supplied with a bottle of test fluid which works well on petrol engines. For those who require a more sensitive fluid for checking diesel engines use L7573 indicator fluid, which changes from red to yellow in the presence of combustion gases.
