Serpentine Conversion
Okay I've found a 68 SWB that I'm probably going to pick up. My question is on the Serpentine Conversion, I understand that a mid 90's model S10 will use the parts that I will need. Also need to pick up the fan from the S10 as it will be in reverse. My question is one the reverse water pump, can I just use the water pump off of the S10? Will it fit? What about the P/S and the Altenator? Will those bolt up to the 350 block in the 68?
This truck's body is in good shape and runs well and I'm only looking at having to replace one small rust spot in the bed. Other than that very solid truck. But I will have to do the Serpentine conversion and also disc brakes which I'll save those questions for later. The guy will let me have the truck for $2500. Is that a good price? There is another truck for sale that's $3500, Serpentine Belt already converted and disc brake conversion completed but it has some rust. The dash has a hole about the size of my fist and the rockers are gone. Which truck would you guys go with? The first truck has a Muncie 4 speed that the guy put in. Any advice would be appreciated, I'm super stoked about this build and looking forward to learning all I can from you Veterans on the board. Thanks |

Re: Serpentine Conversion
The GM Serpentine system is a nice conversion for these trucks. In addition to the S10 the late 80s - mid 90s C and K 1500s are also the same and will work. You need a reverse flow water pump. Pick out a year of the donor and use that year and model for replacement parts, like belts, water pump, alternator, power steering pump, idler pulley and bearings, etc. Best to find a complete donor from a wrecking yard or a friend and get all parts. The upper and lower radiator hose can be tricky. Several members have do this and I'm sure will weigh in.
Additionally, Car Craft did this conversion, very good article, link: http://www.carcraft.com/techarticles...ive/index.html

Re: Serpentine Conversion
So do I use the Alternator and water pump off of the donor car or just the brackets? If I have to order the reverse rotation water pump would I order one for the 68 c10 or the donor car?

Re: Serpentine Conversion
you will need a pump that was used with the serp setup. the alt. will require you to perform the internal reg. alt conversion. its pretty easy to do. i did the swap,and it works great. also, you may need to go to a elec. fan setup, due to clearance between the w/p and your radiator.

Re: Serpentine Conversion
Okay just to make sure I understand (please excuse my ignorance) I will need a water pump for the make and model of the donor car (some s10 probably) but in reverse rotation?

I would also advise junking the CS130 alternator that was used on all of these and upgrading to a much more reliable CS144. There is plenty of swap info out there. It uses the same plug in, so it's a pretty simple upgrade.
