Cooling fan seems to run a lot. Normal? 700 1992

"I never saw the gauge move once warmed up, so I conclude that there is some damping going on in the "normal" range of engine temperatures, just like the later 240's."

My 1993 940 acts very, very different. Although I will admit it has a lot of on-center tendencies, it varies 1-2 needle widths either way of center almost constantly until I am cruising on the highway for more than 10 minutes. The second I pull off and come to a stop it climbs 1-2 needle widths and then drops back to on-center'ish.

In normal summer stop-and-go that is Chicago traffic it uses about 75-80% of the sweep on that gauge and the electric fan only kicks in (AC not on) when it is getting pretty close to the red zone. This is with all new radiator, hoses, heater hoses, etc. Have not replaced the water pump yet nor the coolant temp sensor.
