Question type: Maintenance & Repair

i have a friends 2001 Pontiac sunfire in my shop, with a 2.2.
it slowly over heats while idling. I've already changed the water pump and the
thermostat, i'm stumped. the fans kick on, and it seems to draw coolant fine
when i add it, but its losing it through the overflow tube with the cap on.

How are you bleeding air from the system ?

Also there is a couple of more things to check out. Is the radiator or if the A.C condenser sets in front of radiator is it clogged with dirt and bugs restricting air flow across the coils or cooling ports in engine block clogged clean with a good cooling system flush.

Ive just been letting the air burp itself out of the burp tank/radiator cap

Pull the cooling system down into a vacuum. Then refill it. The instructions with the tool will explain how. That way you can be 100% sure all the air is out. HTH. -Jim

Would i just rent a vacuum at a auto store?

You can probably do that. The vacuum tool I have needs to be hooked up to an air compressor. The compressed air creates a venturi which pulls the cooling system into a vacuum. HTH. -Jim
