[s-cars] overheating dilemma

[AUDIJIM@aol.com]

Tony,

Your Audi 80 V6 (ABC eng. code) has a large air bubble in the system. Behind 
the left cylinder head, you'll see the cross over tube (water pipe) that 
connects to each head for water cooling. There is a small allen key vent plug on 
this tube. It might be hard to see due to the throttle body covering it a 
little. Loosen the plug a little while the engine is running, you'll hear and see 
the air/water come out. If this isn't it, then the thermostat may have been 
installed incorrectly. The V6 engines take a while to bleed all the air out of the 
cooling system. The cylinder heads and the water pipe behind them is a high 
spot for the system and the bleed/vent plug is there for a reason.
