      I picked up a 1995 EXP Limited with 200K miles on it and have been driving it a few weeks now. When I was hauling some furniture around the temp gauge went to hot/overheating. Rested the car and it went away. Drove back and it never went hot again for about 2 weeks. Then it came back and red lined. We changed the thermostat and sensor but it is still redlining. The hoses read 150 degrees so it is not overheating. Coolant is fine and there is no air in the system. So it must be the gauge itself. Had a mechanic check it out and he agrees. Wants $250+ to fix it! Right.

      I prefer to replace the gauge in the dash myself but do not know how to do it. I hear it is hard on blogs but is it? Is worth it. I prefer to not put in an external gauge but will if I must.

      Can anyone help me with instructions?

      Engine temperature sender

      I suggest testing the engine temperature sender before replacing the indicator in the instrument panel. The sending unit is more likely to fail than the indicator. BrooklynBay has a useful thread that lists the resistance vs temperature for the sender.

      Sending unit advise

      We replaced the sensor as we found out that by grounding it the gauge went hot too. We replaced the thermostat as well at the same time.

      Is the sending unit different then the sensor that sits just above the thermostat?

      ECT sensor vs engine temp sender

      The engine coolant temperature (ECT) sensor reports the engine temperature to the PCM for air to fuel ratio computations. The engine temperature sender output drives the instrument panel indicator. On my 2000 SOHC V6 the units have different threads to prevent incorrect installation. The sensors screw into a bushing in the plastic housing. There is a compression ring between the sensor and its seat to prevent coolant leaks. The bushing can spin in the housing if the sensor was previously over tightened. If the bushing spins then the expensive housing must be replaced. Use care when removing and do not overtighten when installing the sensors.

      I had a problem with the temp gauge in my 95 Ex. I solved the problem I installed an Autometer electric temp gauge far more reliable than the stock one. I have noticed that the stock will still read something occasionally
