I have a '97 Audi A6 2.8L V12 with 67Thou miles on it that overheats w/in 10 mins. From the time I start the car. I had the radiator rodded and had flushed the engine. I also tested the block for any combustion leaks and found no leaks. No white smoke comes out from the tail pipe. I already changed the water pump, cleaned the hoses and removed the thermostat. I tried pressing continuously the radiator hose to bleed air out of the system. Inspite of all this, the overheating persists. Btw, the water temperature gauge and oil temp gauge are at normal levels. When the car starts to overheat, water starts to overflow from the closed expansion tank. There is no sign of oil in the water. Could it be that my water jackets are clogged?
Would appreciate any help on this. Thanks in advance.
