Serpentine BELT

Dear sir,
I live in Brazil and I have a jeep cherokee sport 98 w/ac, I need to change the serpentine belt and I would like to know which the model for this car, marks, code and size, ...I don't know which is the right. In Brazil it is possible to find serpentine belts of the marks goodyear, gates and dayco and as I am inexperienced in this car, I need your help.
Thanks.
(sorry about my english)

If your XJ has the 4.0 the Goodyear part number is 4060952, and if you have the 2.5 litre it is 4060910.

Edit: Any one please correct me if I am wrong, Got this info from the Autozone Website.

Welcome to :cheers:

I have had good luck with goodyear and the dayco brands of belts.
