i have changed the thermostat. no water in floor from heater core, all hoses are warm, but radiator is cold with no pressure. heater blows but air is cold. temperature doesn't get above 175, could the radiator be clogged or a sensor be bad. the computer doesn't show any codes

Did you replace the t-stat with a 195° F? Is the system full? Are the heater core hoses getting hot? If the car refuses to warm up, you got a bad t-stat that is sticking open.

i did replace t-stat. the old one was working, and the new one is working. one heater core is really hot, the other doesnt get that hot. i am going to try and flush it and see what comes out. i guess that's what i need to do.
