That's not a serpentine system. That's just a multi-rib, versus a v-belt.

But it's what LeeFred described.

LeeFred, I ran one as you described for a few years without issue, other than looks. Cuz I like the look of stock V belts.

I lowered the alternator with a simple bracket.

After adding AC I have (2) six rib belts. Adjustment from the alternator and the condenser. Much less cash involved than the serpentine kits out there.
