Engine Cooling problem
2001 GMC C3500 Four Wheel Drive Automatic 111950 miles
----------------------------------------------------------------
Low Coolant warning appears ONLY WHEN TOWING my 5th wheel camper. Have changed the tank and sensor, water pump, radiator cap, thermostats. and injectors. Engine temperature does not increase at any time. Small amount of coolant emits from overflow on tank, again only when towing. No trouble codes appear when computer analyzed. Have been to at least 8 dealers and no one can identify problem. Problem began last spring when I had local GM dealer flush radiator.
Have been weighed when hooked up and are not overloaded.
