Question about Cars & Trucks
Is the engine getting to full operating temperature? Can you feel the hoses going into the heater core, are they cooler than the other radiator hoses? Do you have an inline water valve for the heater on the vehicle? If your engine is reaching full operating temperature then changing the thermostat will gain you nothing. If your hoses going to the heater core are not as hot as the other hoses you still have a blockage in the system somewhere, if you have a heater valve in line somewhere, make sure it is operating. Without knowing what vehicle it is you are working on it makes it more difficult to try and help.

sounds like the thermostat is not functioning correctly? either that or not in at all? thus making the water which would normally warm up quickly, warm up extremely slowly and on really cold days not at all? with a 2.6 engine your car shoudl warm up in record time?
