Re: How to purge the cooling system

You'll never get it all out.. well you can open every water port and remove all the hoses and wait for the whole system to air dry but, that would promote more rust in the engine.

Just do the best you can, draining and blowing, you might want to shoot some air through the heater core too.

The air can't hurt anything if it's done the way you describe.

PS: You'll get more water out if you loosen the bottom radiator hose too.
