Hi all,

On my way home from shopping today, I noticed my S60 was very sluggish when
accelerating.  It felt like it lost half it's torque when accelerating.  I
had to rev the engine to much higher rpm before shifting to a higher gear.
I then noticed that my coolant temperature gage has not moved after almost
15 minutes of drivng the car in 31 degree Celcius temperaure weather.  The
temp gage is kind of stuck in the "low" end where it's usually in the middle
range.  When idling, there's is a loud whirring sound coming from the
engine.  I think it's the cooling fan stuck on "high"?  When I reached home,
I turned off the engine - waited 10 minutes and then took it out for another
test drive.  The same thing happened, no power accelerating, constant loud
whirring sound from the engine, and the temp gage stuck on "cold".

Would really appreciate your comments on what you think the problem might
be.  I've only had this car for about 9 months - had no problems until now.
I called the dealership but they could not shed any light and just told me
to take the car in.

Thanks for your help!

Mark
