I've been trying to get my heat to work for quite some time now. I replaced the thermostat and flushed the radiator. I have a mishimoto performance radiator in my car also. I have no heat, but the car does stay at opperating temperature. I just tried to bleed the cooling system by opening the bleeder screw above the thermostat and nothing came out, infact my car almost overheated!. I also noticed water coming out of my tailpipes when i revved it, i dunno if thats a related issue? The in and out lines to the firewall don't heat up as well...

Could this be my water pump gone bad? Or would it be my heater core blocked up?
