If your going to go threw your cooling system, this is a tool you should have in your arsenal. I tried to bleed the air out several times raising the ass end up as high as two feet with no success ( I could here the air in the water pump sounding like marbles tumbling inside) I think it was Mr. Bosswrench that recommended this thing. I have been working on Hot Rods for almost 50 years and me and my garage nerd friends will be using this device religiously ( my nerd friends are so cheap they will just barrow mine).
