Reply to "Air Lift Coolant System Tool"

What I use on Panteras is far simpler- a special funnel from Lisle Tools. This plastic funnel has a series of adapters to fit various radiator caps, and connects leak-free to any car. In practice you fill the cooling system full along with an extra quart in the funnel, then start up the engine. After a few minutes at idle, the thermostat opens and a huge bubble of air rises up, sucking in most of the funnel's extra coolant. At that point, you either add a little more water so there's some left in the funnel, then insert the provided plug, remove the funnel and put the rad cap in place, all before shutting the engine down. Works just fine for $25. Without the thermostat open, air trapped in the heads and block is unavailable to other devices.
Once most of the air is gone, periodic bleeding at the radiator eventually removes the rest. A small amount of air seems to 'dissolve' in water just like those mysterious bubbles that appear in a sealed waterbed. I bled our system as above; the next day, I got a few more bubbles out of the rad bleeder. After a 500-mile high-speed drive to 'Vegas and letting the car cool down, I got a few MORE bubbles! After that, no more air. The vac system might remove this 'extra' air.
