Aftermarket Serpentine belt - VP 21132390

[topcat2vin]

Hi,

Is there an aftermarket belt to suit my VP 4.3 GXI-J

The VP Part No. is 21132390

2nd Question - I want to change an idler pully as is has a small squeek, in my experience with V belts when re-tensioned they have a tendency to break - would this likely be the same for a the Multi V belt above if I changed the idler and not the belt?

Thanks

If you have the old belt, just take it to your local auto parts store....if they can match the rib spacing, the length is the other critical factor.

Any drive belt should be able to be re-tensioned without breaking, as long as it is in good shape. if the idler pulley is noisy, it (it or its bearing(s)) should be replaced.
