    The thermostat needs to be replaced first. if I remember right the timing belt needs to come off to get to the thermostat which is behind the timing belt. You need the Audi special tool to hold the camshafts in the correct position when installing the timing belt.

    • Ha! Well if ya got to do all that just to get the thermostat out, then you know that's the problem. Usually the hardest thing to get at goes bad, seems that way sometimes, no?

    So far all I see is spend money on stupid stuff. How about you telling us if the fans are coming on or not? Maybe you could try to turn on the A/C which should turn on the fans. Okay so you didn't know that? Don't listen to all the "replace this and that bull" and do tell if the fans are working.

      Yes, Mycah, they were recalled after the plastic impeller in the water pumps stared failing. Don't buy a car that is breaking down. Overheating makes other expensive damage.

    Could be more than that. The cooling system needs to maintain pressure to avoid boiling over. It needs the water pump to move the coolant. The thermostat regulates coolant flow. Change the radiator cap. Check the water pump for leaks. Look for other leaks. Have the head gasket tested. Make sure the electric radiator fans work when they should. Make sure the temperature gauge is telling the truth.

    failing water pump, clogged radiator, leaking radiator or leaking hoses, or blown head gasket.

    Do not guess. Troubleshoot. Replace the radiator cap. Replace the thermostat. Service and bleed the coolant. Get a pressure tester and check for leaks. Check for a clogged radiator. Check for a bad cooling fan. Etc, etc.
