How do you bleed the cooling system on an Audi 100?

Answer 1

This should be fairly easy to do. First fill the coolant to the max mark on the tank. Then see if it almost automatically loses some coolant (it might almost burp its self) if it doesn't squeeze the big top tube right next to the coolant tank this will send some air back into the tank. Second uncover the bleeder valve for the system which should be hidden under a plastic cover near the windshield at the back of the engine compartment (taking off the cover is very easy). Look on the driverside near where the coolant tubes enter the heater, there should be a screw valve on the top tube. Third with the coolant tank cap off start the car, get it running hot, but watch the coolant level to make sure it does not over flow. Once it start to get hot, unscrew the bleeder valve and wait until it has a good flow of coolant coming out of it. This should bleed the system. Watch the coolant level, and refill as needed.
