It is the viscous fluid fan clutch causing that noise. For some
reason, you will have occasional colds days that cause the fan
clutch to engage. The result is a truck that sounds like a jet
taxi-ing for take-off for the first few blocks. Quite a few
of the '97 owners have noticed this.
I have noticed that my truck doesn't do it as much now that
it is over a year old. Maybe the fan clutch needs time
to break in?
