The truck had sat for about a year in a airplane hanger prior to me getting it without running. Thats the main reason I changed the waterpump out beacause the fan had some slight resistance when it turned by hand. Prior to trying to start it for the first time since it sat, I had changed all the fluids,removed and flushed the radiator and block since I was changing the waterpump out anyways. They both flushed and ran water through them good and clean. If I remember correctly it might have been a 180 degree thermostat that is installed but not 100% sure of it. I have heard it might be air trapped in it as Pre '68 Dave posted above so maybe I will at least give that a shot. Trying any suggestions before I tear into a head. Thanks for the help everyone!
