Smile Re: having problem w/

It sounds like u have a problem with your Heater Core...

The Water Pump sends the coolant/water mixture to ur engine block, but it goes through your Heater Core in the middle of the "chain" (mounted at ur firewall) via high pressure hose and return hose. It does this to provide the heat from the coolant mixture as the heating source for your interior heating/defrosting needs (via the Heater Core). This is why sometimes when ur engine is running hot, u run the heater to help cool it off (which draws heat from the coolant mixture going back into your engine block). So, u will most likely have to change ur Heater Core (and the hoses too since u will already be doing the core). Hope this helps!

So you think, its the heater core? i was thinking about changing the thermostat and flushing the radiator and radiator fluids. do you think thats a good idea to start with? and also, i get ventilation air from the windshield and foot position only, but not from the one blowing towards me. any idea? thanks.
