This kit combines the unique Mityvac Selectline hand pressure pump with four cooling system test adapters and two dual-function cap test adapters to find leaks and defective caps in the cooling systems of most U.S. and Asian cars and light trucks, as well as many European vehicles.

The MV4560 quickly pinpoints external cooling system leaks caused by loose clamps or leaky hoses, connectors, water pumps or radiators.

The kit also diagnoses internal leaks caused by blown head gaskets or damaged blocks or heads.

In addition, the MV4560 tests radiator and coolant bottle caps to ensure that they are maintaining ­correct pressure.
