My wife drives our 93 as I have a longer commute and use our TDI. So last week I go in for an MRI and drive the cruiser which normally blows hot after just a minute or two. I drove to the hospital and back with nothing but cold air coming out of the heater, front or rear. I got home and popped the hood and the radiator was a little low, but nothing I would normally be worried about. I pulled the hose off the heater valve and nothing came out. I then fiddled withe the valve for a minute and topped off the radiator and started the motor with the hose still removed. coolant started to flow and I put the hose back on and didn't think more of it until I read Idaho's post about his losing heat for a few seconds and now he has a blown head gasket. so, how should i confirm I don't have a blown gasket? The motor has 260K+ miles on it and it would just be my luck to have to rebuild it right now(note- MRI and possible torn ACL and just ahd a baby) Any thoughts?
