So, I finnally got my 81 ram up and running, and, the reason i stored it 2 years ago, was it wasn't cooling properly. I have been around and asked random people and here is what I have already replaced.
-New Radiator
-Waterpump
-Thermostat
-All hoses
-Heater Core
-coolant temperature sensor


I think that it, I dont know what else, but water is not flowing, the heater core hoses are empty, and its not flowing.

Is there any redneck way to do a coolant flush? Should I try replacing the water pump again? I'm out of ideas here and really need some help. Thanks

Its a slant 6, 2 wheel drive d150

 

i think you might have air locked in the lines. ive heard of it but never seen it. but this sounds like it. mabe you can try filling the heater core lines with water then hooking them up.

 

Thanks wolfie, I have done some researching, and some cars have a bleeder for the cooling system, Anyone know if these rams have it?

 

i would pull both of the heatercore line and fill one with water till water comes out the other line. i don't think they have a proper bleeder.

 

Disconnect both heater hoses at the engine. Try to blow air thru the hoses and the heater core. If you can blow thru the heater system try pulling the nipples that the hoses attach to as they can rust shut. If you can't get air to flow you have isolated the problem to the heater system.

 

I will try that tomorow night, the truck is about an hour away, so everytime i want to work on it, i gotta drive for a while. I'm also having problems with the engine bogging down, but I was told its a timing thing. Thanks tho
