This device will purge trapped air from the cooling system and refill it - free of any trapped air. It includes an air operated vacuum pump assembly, detachable heavy-duty vacuum gauge (0-30" Hg), universal rubber body with three additional bushings allowing for almost 100% coverage, liquid line hose assembly, a muffler to dampen noise during vacuum operation, and a flow-control valve." Mityvac also makes some nice fluid extractors for very easy oil changes. Cheers, Jeff C. __ >> I don't think it will work in the coolant tube that I think is getting >> air trapped in it.
