Answer 1

Tend to agree with Dodge Man, I had a vehicle that I kept adding coolant to, it was a head gasket but it was leaking outside of the engine onto the manifold which of course was turning it into steam and there was never a drop of coolant on the ground. It took me a long time to find where that leak was, it was really hidden. I would add coolant about every other month on mine. It was a very slow leak.

As for the A/C not working, that would not have anything to do with your heater core, if you have a bad heater core, I would think that you would have water on the inside floor somewhere or the previous owner would have disconnected the lines going to it in the engine compartment.

Answer 2

its normal for the water temperature to go up for a short time when you restart one like that, as for the coolant loss in it ,you could have a slight leak from a head gasket once it warms up that is only allowing the anti freeze to escape in steam form not liquid form and a leak like that is real hard to find,even a pressure check sometimes wont detect a leak like that,my truck was doing that for two years and i finally tore it down and had the heads checked and i had a tiny hairline crack in one of the heads that wouldn't affect the running part at all but it would open up enough to cause me to have to add about a half a gallon to it every 8-10 weeks,so i fixed it and haven't added a drop to it since then,so that could be where its going to,as for the fan running all the time a bad relay will cause that too happen to it,good luck with finding it ,it only took me two years,good luck.

not accepted i might fill it up one extra time shop a watch on it and then in case you could not locate out the place the problem is take it to the shop you had a great form of artwork completed it incredibly is conceivable there's a loose installation or clamp the is letting the coolant leak out.

Answer 4

It may be leaking into the engine and being burned out the tailpipe.

Gaskets or cylinder head problem. It can be tested.
