I've read the Aug 03 posting of this question, but I'm still concerned about this very loud squeek on shut down when the truck is at operating temp. I use a cool down timer and don't get the squeek when I have to use the truck for a short trip when the truck doesn't fully reach operating temp.

 

There is a bulletin. It's a normal noise.

 

You'll find it getting more and more random as you put some miles on the truck.

New, I'm pretty sure it did it every time.

I don't remember it doing it much at all during this last winter, maybe every 6th or 7th shutdown,
and now it seems like every 3rd shutdown.
A lot depends on if I use the A/C, and for how long.
How long before shutdown did I turn the A/C off, if even.

I've got 15k+ on it, with about 1k towing an 11k lbs trailer and I rarely use the A/C.

 

Are you referring to the belt "chirp"?If so,this is normal,but can be rectified with a Goodyear gatorback replacement belt.

 

That shutdown squeek is normal; the easiest thing to do is just ignore it - another option is to never shut it down.

I smile when mine does it - lets people know there isn't 1.8L buzz bomb under the hood.

 

The Cummins in the Freightliner at a farm where I once worked made the exact same sound (only on a bigger scale).

I think my truck only does it if the fan clutch is engaged when I shut it off... (fan appears to run even if coolant isn't hot if the AC is on, apparenlty to pull air into the condenser).

I wouldn't worry about it. The thing has 6 big, high compression pistons, and the crank accelerates and decelerates a couple of times as a few pistons hit compression stroke before things comes to a stop, and it just chirps the fan belt...
