Block test Kit Fluid for the block tester kit that detects exhaust gases in the radiator and so checks for gasket damage, cracked or warped cylinder head. 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.
