Hello,

As per my other post, I need to change the alternator and thought it a good time to put a shorter belt on to bypass the compressor with the whining pulley bearing. Thing is I can't find the info in the search for the right serpentine belt size for this. Can anybody give some advice?

Many Thanks!

You have only two options avaliable for this engine so you can't pick up the wrong one

I have a belt that bypasses the compressor and also the extra idler pulley.  If this will be the same as what you need then I will get the length from it.

Assuming you talking about the 2.2 diesel and assuming the extra pulley has been removed then you need a PK1425 belt to bypass the AC compressor.

What I did was wrap a piece of string around the pulleys and then measured it.  Worked for me.

I don't know what the he'll is going on. Thank you very much for your replies gentleman. I thought the idler pulley was the belt tensioner.

I'll just replace the alternator along with a standard belt and the A/C compressor can just tear itself to bits. Bigger fish to fry. Thanks again for all the input.

I did this on a 2.2 by wrapping a piece of string around the pulleys and then measuring it.

 

Worked fine for me.
