Car Information:
Grand Cherokee
Year: 1996
Engine Size: 4.0L
Trans: Automatic

Issue / Question:
Over heating, replaced water pump, thermostat (195 deg) and coolant yesterday. Radiator was replaced 4 yrs. ago. Mileage is 180K, temp gauge reads 230+-. However, if you turn the heater on it reads 210. No visible leaks in the system. Please advise, temperature is higher when driving.

Answer:
Is the temperature the same at an idle sitting still, and driving at highway speeds? I would be tempted to try another radiator, it should run cooler going down the road.
