GM Serpentine Conversion Kit
The following system seems complete: 12497698 - Small Block Chevy Serpentine Accessory Belt Drive System "Deluxe With Air". Any installation hick-ups, or is the installation pretty straightforward? Tips or tricks for the conversion would be welcome.

Re: GM Serpentine Conversion Kit
Hi James, I'm getting to install my serp parts from a '90 RS too. I think that GM kit is almost the same the TPI parts. There are two things you need to be aware of. The first is pretty obvious the A/C and alternator swap sides, so you'll have to run wires and lines. The other is the older blocks don't have the second accessory hole on the passenger side. You have to drill and tap one. I'm keeping my fingers crossed that if I just drill only 1/2" it won't hit the water jacket.

Re: GM Serpentine Conversion Kit
Hit Summit and type in the above part number. Then look toward the bottom and you'll see a GM installation procedure that appears to be VERY helpful (torque values and p/n's).

Re: GM Serpentine Conversion Kit
trumps,
Take note of what the guide says about those holes. Beyond the kit, I'll need the A/C hoses, a bit of wiring for the A/C compressor (GM 12101937), and a smog delete pulley (GM-6167), though not absolutely necessary, I guess.

Re: GM Serpentine Conversion Kit
Apparently the fuel line will require some massaging as well.

Re: GM Serpentine Conversion Kit
Actually the fuel line I purchased from Classic tube clears, but I have of issues. How is the stock line run? Mine passes between the water pump and timing cover.

Re: GM Serpentine Conversion Kit
My bad, the kit contains the smog delete pulley (Pulley, idler lower), p/n 10129569. Anybody have an idea of approximately how long the swap will take if I'm prepared with the necessary parts and air tools?

Re: GM Serpentine Conversion Kit
Thanks, I may. I saw that link a day or so ago when I was researching--I wanted to know that the kit was pretty much a bolt-up (and that no drilling/tapping would be necesssary). Pics show three holes on each head of the HO, so I believe I'm good to go in that respect.

Re: GM Serpentine Conversion Kit
Crap. The water pump in the kit won't fit my application (no heater hose connection).

Re: GM Serpentine Conversion Kit
I haven't completely assembled it yet. I've only done a few test fits, so I'm not sure if its an issue yet.

Re: GM Serpentine Conversion Kit
When the time comes, I'd very much like to know (apparently, you're the test mule in this set-up
)

Re: GM Serpentine Conversion Kit
Haha no problem, won't really get to for at least 3 weeks though. Thats when I can park my car in front of my apartment again, street laws
I also have to finish rebuilding my alternator and buy serp blades for my clutch fan. Think there is any problem with spinning the clutch backwards?

Re: GM Serpentine Conversion Kit
I'm currently running the GM "Deluxe" conversion on my 84 TA. I don't recall having a problem with the water outlet at the wp. One problem i did have, was my block was decked so I had some clearance issues to work out.

Re: GM Serpentine Conversion Kit
Another question. Since the p/s pump is relocated in the serp system, can I use the hoses from my current set-up, or will I be obliged to replace?

Re: GM Serpentine Conversion Kit
Well I don't know for sure, but I don't think its relocated much if any. Depending on the bracing behind it you should be able to reuse your lines. The setup I pulled off of '90 Jimmy 4.3L has a stamped brace for the alt and p/s which will interfere with the lines. The TPI and TBI setups use a bar to brace the alt. I haven't seen any factory bracing for the p/s. So there shouldn't be an issue there. I haven't test fit my p/s yet, cuz its a bit of a hassle, but I plan on using my Vbelt pump and so don't plan on disconnecting lines.

Re: GM Serpentine Conversion Kit
Hey James, How did your install go? I'm almost done with mine, but I can't get the A/C brace to fit, the TES headers. How did yours go in, got any pics? The system is out of a 92 RS, but I believe its identical to your kit.

Hey, trumps,
Sounds like you need a spacer. Here's my write-up (and some pics):

Re: GM Serpentine Conversion Kit
The problem is that the #2 exhaust tube comes up and over the #4 and #6 tubes, so it intereferes with the brace.
Looks like Edelbrock already knows this, I just have to bend the ends of the brace.
