Time to bypass the temp compensation board... but... 200 1992

The Volvo thermostat specs for the B200F are the same. This problem came on relatively recently and may be worse after the anti-freeze change? If so then you may have an air lock on the block side of the cooling system. Happened to me once after a water pump change and the temp needle went high, but I soon realized what was going on. When you installed the new thermostat, did you make sure it was installed right way around with the spring side down into the block and coolant? Did you make sure it was turned with the little jiggle valve weep hole at the top?
