I am trying to find out how to bleed the radiator and where, I've searched but to no avail can someone tell me or give me a link to a thread. Plus is there some reason my lower pipe should be cool when my upper pipe is hot? I replaced the thermostat already and it didnt help.

just fill it slowly. also, did you remove the coolant drain plug from the block to drain it, also? There's a water jacket plug.
