Noticed today on start up the rad fan spools up way beyond normal, sounds like a small jet winding up and back down when I shut the engine off. Coolant is up, heat and cold are working. Dash temp. gauge reads cold after several minutes running. Any ideas?

 

Not sure, scan by Volvo.

 

Thanks for the comment, it's a ways for us to get to a dealership, but I guess that's the likely path. Are these fans supposed to be variable speed or just on and off as required?

 

They are variable, you might have a sensor reading faulty or something along those lines.

 

I would think so. It appears to be reacting to wrong information. Another site suggests the thermostat for a similar problem. He acknowledged it seemed counter-intuitive, however it was the fix. I'll report back after I take it to the dealer.

 

Problem solved for now. Pulled connector of heat sender and reconnected it. Fan operates normally.Thanks very much for the suggestion.
