I have noticed over the last week, a squeak from the engine compartment as I drive when cold. This lasts for only a second while a go into first as I drive away.

Very quiet but never the less noticable to me.

I'm thinking......happens only when cold, only for a second or two.... BELT!

The belts must have stretched a tiny bit over the last 3700 miles. Also there is no pretentioner that I can see. The adjustment is manual. There are two belts. The wider of the two drives the alternator. My scientific method of determining which one I would adjust came down to which one felt looser.

The Alternator belt has a tiny bit less tension by touch. I figured I would only adjust a small amount so that even if that belt was not the culprit, the extra tension was a mute point.

The adjustment was very easy. A 12 mm socket is all that is needed.

First just "crack" the bolt on the slide. Then turn the adjuster bolt a few times. I only moved it 1/8 of an inch from its original position.

I will know in the morning if this was the problem.

 

You can see how much adjustment was made in this pic.

 

this is the adjustment bolt.

 

you rule. thanks for the pics.

 

Thanks for the tip. Something to keep an eye on here now that winter is just around the corner here in NH.

 

Did that cure the problem this morning?
