2003 Audi A6 Quattro Q&A
2003 Audi A6 Quattro Question: car is overheating while idling and moving?is it the Thermostsat or water pump?
First my my reservoir cracked then while idling it had water running all over the place ,,I fixed one of the problems and had a few hoses and clamps replaced but it won't stop running hot . It starts getting hot after only 15 mins while driving then when i pull it over to cool it goes to the normal but then the i have to check the reservoir the coolant goes down and then the pressure is so built up it pushes the coolant back up to the I really need help with this - Cmo1
these engines have plastic water pump impellars,most likely the impellar has fallen apart. very common. - globalhelper
Sounds like you have an air pocket in the cooling system. Let it run with the cap off and fill coolant. Make sure the cooling fans are working. - jasong711
