    Will GM\'s serpentine belt system fit 87TBI?

    I just need power steering and alternator, no AC, smog or idler pulleys. Can I just get the parts for my setup, and will it work without any of the other accessories?

    Hmm...Monte SS's in '85 got a hybrid serpentine/V-belt system ifyou can find someone parting one out. Perhaps Camaro's same vintage as well. Problem I'd imagine (not knowing how that system was setup) is that the crank pulley probably needs both a v-belt groove(s) and a serpentine "flat" to run all the accessories.

    if you want the whole set up pace parts sells the whole kit everything needed to convert to serpentine system...i think the cost is right around 550 or so...

    My 87 has a serpentine belt for the Alt., & water pump. The power stearing has a reg. V-belt so i'm sure you can get it to work. check the junk yards.

    I'm selling an entire set of v-belt/5-rib serp belt pulleys in the parts for sale forum.
    They were originally on my 1986 Fullsize GMC Jimmy
    The pulleys as I've already stated use both; serpentine belts as well as v-belts.
    I have the entire set of pulleys:
    Crank,Waterpump,alternator, power steering for $50!
    I'm also selling a set of all serpentine pulleys from March
    March part# 6380 for $130; These are Billet Aluminium and I'm quite sure will underdrive your engine.
    You would still need to purchase from March the PS pump pulley and the bracketry. I've got this same setup on my '77 Blazer.
    Stop by and check out the stuff I'm selling in the other forum if you'd like.

    If you are talking 1 belt type serpentine, like a newer model, you will need to change to a reverse rotation water pump. I think that is the only acc. that turns backwards w/ a single belt serpentine. If you are talking about the serpentine/ V belt set up like some of the older models had the pump rotates the same direction as it does now.

    Serp systems are nice but if one component fails on the trail you are screwed unless you have a spare component and the time, tools and patience to change it where you are or drag it home or to the shop. Just food for thought.
