As I'm always the pessimist, I hope it's not a blown head gasket or cracked block. That would cause both the running issue, and the overheating issue, and would be much more likely if you look in the radiator and see that it has just water in it.

Usually overheating issues are caused by a leak or stuck closed thermostat. My mind runs to the worst because of the multiple problems, and usually when one point of failure can cause all the noticed problems, that seems to be what it is normally.

The oil is black and dirty, no foam or "chocolate milk" LOL and the antifreeze was still nice and green. We had no heat in the cab either, so my first thought is the thermostat. We will play with it some more soon, and start figuring it all out.

Well, my fears are at ease. No heat in the cab isn't caused by the thermostat though. Water circulates through the heater core even with the thermostat closed. That means you may have a water valve not open, a bad water pump, a blockage in the heater core, or the water level started out so low that by the time it heated up any, all your coolant had simply become steam, which doesn't tend to pump through heater cores very well.

Congrats on the new ride. Have you checked yet for all the cool stuff like :is the build sheet under the seat? What was it's original color? If the engine is original it would be the 230.

PoDuck, the blower motor isn't working, and between the holes in the floor, and no seals on the floor vents, it may have been warm, but we were not able to feel it. LOL

Spud 63 it does have the build sheet behind the seat. It is the original white. I found a story online that said the 250 had a dual groove pully on the crank and the 230 only had a single. I havent had time to find more info about it.

I agree

Welcome to the forum

Congrats on the new truck. Without the blower motor working, you won't feel any heat in the cab. If you put your hands on both heater hoses and if they are both warm, you will have coolant running thru the heater core.
