Hm, that's weird. As long as it keeps operating normally now, it should be fine.jmcguire wrote: ↑08 Apr 2020, 06:17 The 850 passed state inspection and emissions testing with flying colors at 65328 miles on the odometer.
At 65450 miles the engine cooling fan wasn’t shutting off when turning the ignition off. It would continue to run for about a full minute before turning off. I replaced the fan relay and the coolant temperature sensor. While doing the work I flushed the cooling system and replaced the Stant thermostat with a genuine Volvo one.
One note... when I first started the car after replacing the sensor and relay the fan kicked on immediately. I shut the car off and it continued to run. So, I restarted the car and allowed it to idle until eventually the fan turned off by itself and it is now cycling perfectly. Might have been stuck in mid-cycle and needed to reset.
I know if the engine temperature gets to a certain amount, usually only on really hot days, the fan will continue to run for a minute or two after turning the key off.
