My truck started running hot this past Saturday. The truck has over 270,000 miles on it but the engine has been rebuilt about five years ago and has about 50,000 on the engine. Never ever ran hot before in twenty plus years. Replaced the thermostat, temperature sensor, radiator cap, and water pump is only two months old. Radiator about five years old. Condenser does not look that bad but I am going to pressure wash it tomorrow to be sure. My overflow reservoir is overly full and stays full running and stopped. When it overheats and l stop, my coolant reservoir is just boiling, never running over just bubbling. Cooling fan is belt driven by the water pump so it seems to be okay, not loose or anything. After the engine cools down and take the radiator cap off I cannot see any coolant in the top of the radiator. What your diagnosis? Kind of want to be sure it is what I think it is.
have the same problem?
