Engine Cooling problem
1999 Dodge Ram V8 Two Wheel Drive Automatic 131750 miles

Engine very seldom reaches normal operating temp nor will the heater get beyond warm in winter, even after 20+ miles. The only time it will reach normal temp is when idling for awhile with an outside temp of 95+ degrees. I have changed the thermostate 3 times, radiator flushed twice,water pump and finally the fan clutch.

Hi Bholl
Is the thermostat a 195 degree? Most like a cool running engine your's seem like an ice maker. You make need to block air flow to radiator as an option.
Let me know
