I don't know was wrong with it but I need it fix asap.

From a cold start the truck begins to build temperature almost immediately. I have changed the thermostat and in the process i hooked it up without the thermostat to make sure the water pump was working (it was). The return line that comes from thermostat back to top of radiator is building a lot of pressure and does not seem to be getting hot at all. why is the truck getting hot? also, if i take the radiator cap off while the truck is running it will actually start pushing fluid out.. light it doesnt have anywhere to go
