Question about 1991 Chevrolet C1500
At normal operating engine temperature, gauge in cab reads high.
the following have been replaced in the last 7 months:
serpentine belt, thermostat, engine coolant, radiator hoses.
Faulty temperature sensor I think, thats what feeds the gauge. If the vehicle is genuinely running hot there would be a lot of pressure in your radiator causing overflows/steam/coolant smell.
Those sensos wear out and commonly go to short which shows a higher & higher reading until they fully short out
...hope that helps.
