I have a 1989 Chevy 1 ton c3500. The fudge tells me it's getting hot but it doesn't run like it's hot. I've had the radiator rodded and the gauge says it's getting hot still.

Question type: Maintenance & Repair

I took the thermostat out to see if I had flow
in the radiator and I do. I put a kitchen
thermometer in the radiator with it running
and it said 180. Could I be getting a false
reading?

With the ignition on I unplugged the wire from the sensor and the gauge read zero. I then grounded it to an alternator bolt and it maxed out. Is this an indicator that the sensor is bad?

it should run around 190 sounds like the sensor is bad
