Serpentine belt replacement and diagrams?

You would need a ratchet and a torques socket to release the tension. While looking at the crank. The tensioner is on the right side #3 on the diagram. Where you install the torque socket is on #4 and go ant clockwise to release the tension and remove the belt. Reverse order to install. This video will show you how

I can only find a diagram for A/C and no A/C see below. What does the second belt drive?

Yes I know that but it gives you the option of a/c or no ac does the smaller pulley drive the act alone?, Can you align the pulleys by eye and tell me what each belt drives?

Can you post the VIN this may be the only way to find the correct info for your car

I put that VIN into Mitchell one data base and came up with not very much, it did show a poor line drawing of the 2 belt system but no detail, I am still looking, but it is proving to be quite hard to nail down.

Might be the wrong type Poly V belt

The belt is probably still loose-also it has to have the OEM part drive belt/s
