Serpentine Belt Diagram

[SayBye]

My 91 4.0 longbox threw and shredded the belt last night. No diagram under the hood. Any of these look familiar? It is an AC truck... these all look similar. Guessing this is what I need, each one just just a little different from the creators perspective...

My 91 is the same as the top left picture.

Just remember, grooved pulleys get the inside (grooved) part of the belt, smooth pulleys get the back side of the belt.

Nailed it. However lining the power steering pump back up was a pain in the butt. Coulda used another set of hands but I finally got it. Thanks y'all!

I need a belt diagram for a 1990 2.5l with AC.

I don't think that diagram is acurate. The alt is above the AC and a small idler to the lower right of the alt.

That's what my belt routing book says for 87-89 2.5 w. air. maybe the 90 is different; I don't have that one. maybe someone else will chime in...

[swsws1]

I looked at the routing diagram on advanced autos computer and theirs is the same as you showed me. It's all good brutha someone will lead me in the right direction.

Pick your poison. From the '90 FSM.

My alternator is top left above the AC with a small idler to the lower right of the alternator

Are you certain the a/c is factory? Pretty common as a dealer add-on. It's also not uncommon for an alternator to be relocated for better water fording ability.

you never need a diagram if u just follow what paradisemj said. it works for every car made!!!!!!

[swsws1]

True. But then the problem is belt length.
