96 volvo 850

Is there anybody who can help me to understand my 96 volvo 850.

Anytime when I stop the car and turn the engine off, the fan keeps
running for about five minutes before stopping by itself. Is this
anything that I should be worrying about? because it did used to to
this.

On my 97 850, the cooling fan runs briefly after I shut off the engine
but clearly not as long as one minute.

My suspicion would be that your fan's temperature sensor is faulty. I
*think* it's located on the inside face of the radiator and has a wire
running to the fan.

I have an adjustable thermostat on my 760. I set it to run for approx 5
minutes after I shut off the engine. The coolant still circulates through
the block because heat rises/cold falls, so it doesn't hurt to help it along
by taking some of the extra heat out of the block, especially in turbo
applications, which I have.
I wouldn't worry about your fan running a bit after you shut off the
engine, it's only helping to cool things down, and not costing any gas.

That's not totally right. The fan runs on the battery, which needs to be charged
(just a little bit) extra when your engine runs again. Which, on its turn, will
cost you (just a little bit) extra fuel. But I guess that's just peanuts
