V-belt To Serpentine Conversion Kits

All American Billet’s Chevy Small Block Serpentine Accessory Drive

By Rob Fortier   –   Photography by Grinder TV

When function and form become one it is a well-designed and equally good-looking product, such as a machined-aluminum front drive system for your truck’s engine. Whether it’s a Ford Y-block, Hemi, LS/LT, Coyote, or a good ol’ Chevy small block, our pals at All American Billet have a serpentine kit just for you. (Matter of fact, they have kits for FE/Cleveland and small-block Fords, small- and Chrysler big block, Chevy big block, and even a 4BT/6BT Cummins diesel!)

All American Billet Serpentine Belt Conversion Kits easily convert V-belt pulley systems to the modern OE-style six-rib serpentine belts. The complete Chevy small block kit is designed for the short water pump and includes an alternator bracket, GM Type II–style power steering pump, Sanden SD7B10 AC compressor, alternator fan pulley with cover, water pump pulley, crank pulley, power steering pulley, spacers, belts, and hardware.

Unless you’re going for that purest/vintage look and have nothing more than an alternator/generator spinning off your water pump, consider ditching that old V-belt setup for a more reliable, more efficient, and definitely better looking serpentine-driven accessory system. All American Billet offers not only the above mentioned variety of fitment applications but accessory options as well.

02 There’s a huge variety of stock V belt configurations on Chevy small block engines so we’ll skip the teardown portion and move directly to the pre serpentine prep
There’s a huge variety of stock V-belt configurations on Chevy small block engines, so we’ll skip the teardown portion and move directly to the pre-serpentine prep. First and foremost, carefully—and thoroughly—remove ALL gasket AND sealant material from the water inlets/outlets. Then, just as carefully, chase all forward-facing mounting holes (with a thread chaser not a thread tap!) to clean out any old Loctite and/or sealant. (Also, verify the timing cover is sealed and not leaking, as now’s the time to address that!)

General Motors introduced a single belt serpentine drive with the debut of the ’88 GMT400 pickup line, better known to most of you as the OBS, almost 10 years after Ford had already started using the auto-tensioned system in the Mustang IIs (it was originally designed by Gates in 1974)! So, if the OEs have been relying on serpentines for the better part of the last half-century, why aren’t you?!

Just to show how easy the conversion from V-belt to serpentine is, we present you the following install of All American Billet’s complete Chevy small block front drive kit, which doesn’t require much more than basic mechanical knowledge, a good set of tools (yours or your dad’s), a free afternoon, and, if possible, a helping hand with a few cold ones to celebrate your achievement!

04 When installing the water pump there are a couple different ways of going about attaching the gaskets
When installing the water pump, there are a couple different ways of going about attaching the gaskets—as long as you do so in a manner that “seals” the pump to the block you’re good! Use just the upper two (temporary) mounting bolts and spacers, but do not fully tighten yet.

06 Next install the main accessory bracket using the supplied standoff spacers with corresponding Allen bolts on the lower two water pump holes
Next, install the main accessory bracket using the supplied standoff spacers with corresponding Allen bolts on the lower two water pump holes. Again, do not fully tighten yet. (Adding a dab of RTV silicone to the ends of the bolts doesn’t hurt.)

08 Replace the temporary spacer bolt on the driver side with the two piece spacer
Replace the temporary spacer/bolt on the driver side with the two-piece spacer with the elongated lower alternator mount against the water pump, as shown. Again, do not fully tighten yet!
09 Repeat the procedure on the passenger side with the AC pump bracket
Repeat the procedure on the passenger side with the AC pump bracket, followed by the AC pump (“tighten just enough to hold in place,” as All American Billet states).

With the pulleys securely attached, your serpentine drive is almost ready to be “belted” up—but first, install the tensioner to keep that belt tight and in place!

18 Using the supplied instructions for reference route the serpentine belt into the drive system
Using the supplied instructions for reference, route the serpentine belt into the drive system—load the tensioner using a 1/2-inch drive socket wrench or breaker bar (that’s what the square hole’s for) to secure the belt once properly in place and seated correctly in/on all the pulleys.
19 Finish the front of the drive assembly off with the tensioner pulley billet cover

22 Lastly you’ll need to find a suitable location to mount the new billet power steering fluid reservoir
Lastly, you’ll need to find a suitable location to mount the new billet power steering fluid reservoir—typically, off the radiator core support directly in front of (and above) the pump works best. Not included in the kit are the appropriate power steering high/low pressure lines and fittings, which you can either have made to fit or purchase separately already cut to length with fittings installed.
23 With your front drive system fully buttoned up follow All American Billet’s in depth instructions
With your front drive system fully buttoned up, follow All American Billet’s in-depth instructions on fluids and everything required to get your truck back on the road … then, enjoy the modern fruit of your labor!
