TEMPERATURE GAUGE

1994 GMC Truck

Engine Cooling problem
1994 GMC Truck V8 Four Wheel Drive Automatic 129000 miles

The temperature gauge on my 1994 GMC Sierra 1500 truck keeps showing that the engine is overheating when it isn't. I replaced the thermostate, the radiator and the water pump before I realized it really wasn't overheating - is there a sensor that could be faulty? Where is it located?

Yes, there is a coolant temp sensor, but the locations are different on each vehicle. It also matters if you have a light, or a guage. Check with a parts store, and they can tell you the location for your application.
