CURING TRAPPED WIND

There can be few jobs more disheartening than renewing antifreeze. You drain the old coolant out, carefully mix the new stuff up, pour it in gently, and then your engine has an airlock and throws it out all over your drive.
Air locks have always been a problem in cooling systems, and they're even more so on today's engines. But Garage Equipment Technologies has come up with a clever, and very simple, solution to the problem: get rid of the air and you can't have airlocks!
Like a cooling system pressure tester, Airlift II locks onto your radiator top or expansion tank filler.Then it uses compressed air, through a venturi, to create a vacuum in the entire cooling system. Next step is to simply place the feed tube in a tub of ready mixed antifreeze, open the valve, and let the negatively pressured water jackets suck the fluid into all the darkest corners.
Another advantage of the tool is that any leaks in your cooling system will immediately show up, as the vacuum pressure will only stay constant in a completely sealed system.
