Ok i have replaced the thermostat, radiator, water pump & the heater core all within the last year. But once again my heater wont blow hot air. The motor temp stays around 220 but my bottom radiator house stays cold & the heater hose that runs to the pump wont get hot either. The other heater house gets hot as does the top radiator hose. So clearly its not circulating coolant. But why not? The water pump does not leak nor does the heater core. How can i figure out which part is causing this & why does it keep having this problem even when new parts are installed?
