1992 Plymouth Sundance 2.5, 4 cylinder. After driving 4 miles the gauge in the dash begins climbing. It stops just below H after about 2 miles and begins to recede to half wayand stays there during unexerted driving. During a steep climb on the highway it begins climbing again and on the down side it receides. After getting off the higway the climb begins and at 5 city blocks it is just below H and stays there until I turn it off. The fan is running, I have checked it at the side of the road.
I have replaced the thermostat, the coolant temperature sensor, two hoses and had the radiator flushed. After replacing the therostat and coolant sensor it ran cool for about 4 days and then began the same overheating pattern again. What do I do next?
