I am trying to run test to figure out why my Vision is heating up. Hopefully I didn't warp a head or blow a head gasket. Could you please tell me what parts are related to the cooling system so I can check before I junk the car.

Do you mean it's "overheating"? It's supposed to heat up. You have a Chrysler product; AMC went away in the 1980s. They don't have very much head gasket trouble with these engines. If you provide some basic information, we might be able to give some suggestions. In particular, if it only overheats when stopped or at low speeds, you might just have a fan not turning on. If it's worse at highway speeds, you could have a radiator that's partially plugged or has the cooling fins rotted away.

Well, I don't know now. I ran the car idle for about 45 min. And it never heated up. I drive the think for two hours and it's getting hot. So I add some coolant, about a gallon maybe. I checked for leaks and there is none and no smell of coolant or white cloud of smoke coming out the exhaust. The coolant fans are working, at least when I looked thery were working. I am thinking water pump impellar is broke or the lining of a heater hose or radiator hose lining is collasping on the in side causing no circulation. Electrical? I don't know.

I never considered the water pump impeller. That's real common on Volkswagens. What is the condition of the radiator cooling fins?

The fins rotted away on my 1988 Grand Caravan. Anything over 60 mph AND 60 degrees and it would run very hot. Slow down to 55 mph and was better. All winter it was fine. The next summer it ran hot over 40 mph.

The fins and the radiator look and feel fine. Is there a sensor that causes the fans not to work and then work. Is there a sensor going out. The fans work one min. Then quit the next.
As long as I was moving, the car didn't get hot. Couldn't idle very long. Then all of a sudden it just stayed hot, didn't matter how much I cooled it off. It got hot right a way. I think I really ruined something this time.
