IMPORTANT

This is a diagnostic aid. A positive test indicates the presence of combustion gases in the cooling system and should be followed by further diagnosis to determine the exact cause.

Always take extreme care when working with a vehicle cooling system. Never remove the radiator or expansion tank cap while the cooling system is hot or pressurised.
