Hello to the experts out there - this is a head scratcher. Okay here's the background: Bought an 82 300TD from Florida up to NJ. Great car. Love it. Alright so far, you're thinking, right? Well, weather get's cold last week, drive my wife and two kiddies (one an infant) for an hour trip. Cold out. Try heat. No heat. Get to destination. Turn engine off, turn key to third position with engine off, heat! Hot! Hot heat! But start the engine and...no heat. Popped the hood, auxillary pump seams to be working, core is not plugged, monovalve appears to be functioning. I tried again and again with engine on and once the engine is running the heat turns cold almost immediately. I do not know what to do. This is one for car talk.

Anybody have a suggestion? I am supposed to drive the car up to Montreal to see the home opener against the Leafs this Saturday and I would love to take this car instead of my wimpy Volvo. I mean, this car was built to drive to Original 6 hockey games! So, I pose it to you. Can you help me?
