Re: Quirky temperature gauge? 200 1981

I believe the original problem in this thread involves the thermostat, plugged radiator or poor air circulation. Your problem however sounds just like the one I had in my '86 245. As far as I know we have the same temperature compensation board in the instrument cluster. If so, you might try what I did. I removed the cluster, opened it up and removed the temperature compensator board. I resoldered the board just like we do with relays, carefully scraped the board connecting pins to clean them, cleaned the two connections to the temp guage, and reassembled/replaced the cluster. My temp guage is now reading normally. It's not really a hard job to do. Make a note or drawing of where the different wires connect to the back of the instrument cluster.
