My temperature guage on a B20 Amazon (1966, later engine), does work. It starts cold and then correctly rises on warm up, stopping somewhere in the middle. All good so far. However on long drives it will then start a regular cycle of sweeping right to the hottest end, staying there for 5 seconds, and then sweeping back to the middle. It will do this continually. I have replaced the thermostat which didn't solve it.
Do you think I should go to the expense of getting a new guage, or is something else the culprit?
