Default Belt size for 3.4" pulley

Will a stock belt size still fit for a 97 SSEi with a 3.4" pulley? If not how much shorter will I need?? Thanks

You need a 660 belt.

The stock belt will fit, but you should get the smaller one ASAP, to insure that it isn't slipping. Incidentally I have been on my stock belt and 3.4 puley for several months now with now problems.

I don't know the exact part # for the Gatorback, but it will end in 660.

I'm running a Gates */C 660 belt with no problems.

I don't know about the pre-00 SSEi'*, but the 00+ SSEi'* have a longer belt stock than the GTP'* due to the different coil pack setup. Since the earlier SSEi'* didn't have the upper motor mounts either I would guess they would be the same. If thats the case, the stock belt is a 72.5" long belt, and with a 3.4 pulley you will need a 71.5" belt. Most part numbers for the belt will end in 715 (meaning 71.5 inches).

Edit: Just looked it up, and the pre 00'* do still have the longer belt. So you will need a 71.5" long belt.
