1994 Volvo 940 Q&A

1994 Volvo 940 Question: I have a good amount of coolant dumping onto my exhaust.

I cant see in there very well but it seems to be coming out of the draincock area. Not 100% but wondering if draincock could fail or open on its own. I have had the car for about a year without this problem. Should I just try to tighten draincock? -
Answer 1
pressure test cooling system -

I think your right. After further inspection it looks like it might be the metal heater core return tube. In any case I had better test it to pinpoint the leak before I start trying to fix things that arent broken. Thanks for the reply. -
Answer 2
same thing began occurring with My car..long story short, heater core was the culprit. If your car idles in traffic or say, in the drive thru for five+ minutes, has steam ever come out of the vents into the car? Bad. Replaced and symptoms stopped. g'luck -
