Does anyone know what the calibration is on the temperature gauge on a '95 SL2. The gauge rarely reads above 1/4 and usually stays below 1/4 when the car is in motion. When idle, the gauge will go up to 1/2 but will quickly drop to below 1/4 when in motion. The reason I ask is that the heater does not really seem to put out as much heat as I would expect. With the outside temp. around 35-40deg. and the car in motion the temp from the duct is only about 85-90 deg. When in idle and the temp gauge is at 1/2 the duct temp is about 120deg. Does this seem normal or should I suspect the thermostat is stuck open? or that the heater core is clogged? ( wonder what it will be when the outside air temp is down near 0 ) Seems that on other cars that I have owned the duct temp stays pretty constant at around 120deg. Does the Saturn temp run really that much cooler? Just curious what the temp scale on the dash really indicates as far as temp. Any comments?
