BC Bronco's serpentine conversion

Post by only broncos » Thu Jun 10, 2004 11:23 am

Is anyone familiar with Chuck's conversion kit. What is the donor vehicle those brackets come off of?

I can't speak to Chuck's kit directly, but I do know that several people have gotten the serpentine conversion parts off of Explorer, Mustang, and even Crown Cictoria 5.0 motors. If you do a quick search on this site you may be able to find info on the specific differences of each. Someone on this list sells (or at least used to sell) a conversion using the Explorer parts at a pretty fair price.

i think primarily is the ease of use....lower tension levels on the accessories, greater longevity in the belts, super simple belt swapping in pretty much seconds and better belt engagement on the accessories.

Before I put in the 5.0 in I had v-belts on my 302. They worked fine and I wouldn't have changed them to serpentine while I had the 302. However now that the serpentine is on the 5.0...it's way easier to deal with than the v-belts.

I installed the BC serp system on my '72 a while back...

I was adding power steering and needed the brackets, so instead of buying the v-belt brackets I got the serp stuff. I believe they told me the brackets are from an 85-89 mustang, but I can't confirm that...

I had to grind a little on one of the brackets to clear the 3G, but other than that it was pretty much a bolt on. I have the A1 Cardone (Saginaw type) PS pump, and the 130 amp 3G alt. There is a crank adapter (from 3 to 4 bolt) that means you don't have to mess with your harmonic balancer. Also, the reverse rotation pump bolts right up to the timing cover...

The fan was really loud, & I have quieted it down a little with a different spacer, but no overheating problems so far...

As for pros for the system...I have not had any issue with belts slipping, tension problems, alt charging, cooling, etc. and ease of use for installing or changing belts was a snap.

Cons...I recently had a PS return line hose develop a leak (oops, I didn't notice the small burr on the inlet pipe)...with the single belt, you can't just remove the PS belt like in a v-belt set-up. I wasn't sure how far I could drive without fluid in the pump (while it was pumping)...so I was stuck fixing the line there instead driving to a more convenient place...not a huge deal, just an inconvenience.

I can e-mail pics if you need them...

Another reason that some of us are looking into the serpentine, along with the simple maintenance, is that some of the later models had better radiator clearance to make it easier to mount an electric fan. Still a big maybe, but more clearance seems like a good thing.

Here are some of the pics...with this setup I'm running the rigid fan & have about 3/4-1" fan to radiator clearance...

Last Few Pics...One note, this set-up is working great, but I am planning on changing over to the Explorer set-up to get a fan clutch & more radiator clearance...

Also, with this set-up I had to make a little bracket to keep my upper radiator hose off of the idler...I think BC has the P/N for the correct hose, but I wanted to get it running so, I just hacked the bracket! (you can see it in the last pic)

Heylouie00, thanks for the pics. Now I have a lot clearer "picture" of what I need to be looking for. I assume the A/C compressor mounts driver's side top. My concern is that all devices seem to have a healthy amount of belt wrap on their respective pullies except the A/C compressor. Guess I should give Chuck a call and ask him about that. Thanks again.
