Gauge showing over heating but van is not any
thoughts on problem

1 Answer


Sounds like either the temperature gauge sensor/sending unit is bad or the wire(s) going to it are shorted to ground. Unplug the sensor, for testing purposes, and see if the gauge stays on cold. If so, sensor/sending unit is bad. If the gauge is still pinned on hot check the wiring going to the sensor for a bare spot that's touching metal. If all this checks out, gauge on dash is bad.
