My '97 Taurus's isn't blowing warm air. The coolant system has been flushed, and is good to about 30 below (it's 2-degrees outside today). The blower is working, and the ducts route the air through the selected ports. I can see the blend air motor moving the metal arm that opens/closes the door. I can actually hear the door hit its limit point when turning the temp dial to max. Wen driving, I've noticed the temp gauge approaches near full hot on occasion, but settles back down to normal after a short time. When the car was cold, I check the coolant level and it was low. I added to the full line but when bringing the car to normal temp, the pressure forced some of the coolant out of the cap. The thermostat is new, and the upper radiator hose gets hot when it opens. The two heater core hoses don't seem to get hot, but the bypass hose gets hot shortly after the thermostat opens up. I clamped this "bypass" hose shut to see if the two heater core hoses would get hot, but they did not. I did this for about 5-minutes. While clamped, the temp gauge read normal and still no heat. I disconnected the heater core hoses at these "T" connectors and ran water through them just fine - no apparent obstructions. The water pump isn't leaking or making noise. The belt appears to be in good shape, but I don't know how old it is. What do you suggest? Thanks in advance...
