Mity-Vac MV4533 Cooling System AirEvac Kit

The MV4533 Cooling System AirEvac Kit refills automotive cooling systems in seconds, while eliminating the risk of trapped air. The kit combines Mityvac�s universal cooling system adapter with a powerful, compressed-air-operated venturi vacuum to quickly install and evacuate air from an empty cooling system. Once purged of air, the system can be monitored for leaks before using the vacuum to draw in new coolant. The entire purge-and-refill process is simple, clean and reliable
