Laser 5524 CO2 Leak Detector Kit Product Overview Used to detect leaking combustion gases that may find their way into the cooling system when a head gasket blows or block cracks. Product Details Checks for cracked cylinder heads and blockages, blown head gaskets etc in petrol and diesel engines. Supplied with a cone adaptor and fluid. Once fitted to the running engine’s coolant filler neck, the rubber bulb is used to suck the gasses that collect in the top of the filler bottle through the fluid in the tester. If there is CO2 in the gases it will turn the fluid green indicating a blown head gasket or similar issue. Fluid available separately – please see Laser Part No.
