1996 Ford Ranger Two Wheel Drive Manual 187000 miles
1996 Ford Ranger XLT, 4-cyl, 2.3 litre engine, standard transmission. The engine seems to be running too cold. Temperature gauge hovers 1/8 to 1/4 inch above the cold mark in the summer and is below or at the cold mark in the winter. Outside temperature is currently minus 20 deg Celsius (minus 4 deg Fahrenheit). I have completely blocked off the radiator and the gauge is still hovering from 1/16 inch below to 1/8 inch above the cold mark when I have the interior fan turned on. Gauge rises a little when the heater fan is off. The air from the heater is warm but not hot. When the thermostat opens up the temp gauge drops & then soon recovers. Cooling system is full. Antifreeze mixture is at 60%. Radiator cap is functioning. Cooling system is free of air bubbles. No bubbling noise from the heater. Engine temp did increase once when the interior heater was completely turned off. At that time the gauge went about 1/3 of the way up and there was an increase in engine idle speed at stop (rose to 1900 rpm).
