Caprice 1994 gauge temreture low all time

SOURCE: fuel guage sender unit

Check fuse 14 in the facia fuse box,this is the instrument panel fuse.Also check you have a good earth on the connector under the left rear trim panel.

SOURCE: Temperature Guage, '89 Camry

the cable going from the gauge to the sender unit is an earth return. if you take it off the sender unit wire if the gauge does read hot the sender and earth it out the gauge should go to the hot segment.dont leave this cable to earth very long do it quickly. if the gauge does read it is ok, there is no earth to the petrol tank. if it does not read it will be faulty. hope this helps.

Flushing the radiator, replacing the radiator cap, adding new coolant, replacing the sensors and a new thermostat solved the problem. Probably didn't need to do all of these things - but since we just purchased the truck, and given the fact that is probably hadn't been done in a while, we chose to do all of these things (which really didn't cost a whole lot), it's running like a charm now.

Hello l_anderson36: My name is Roger and I will help you. You should find the map sensor at the front of the engine. Located on the drivers side of the engine. The sensor will have a plug with three wires on it.
