Serpentine setups..info please

[Cherub]

Thanks larry that answered my question

[staggerd86c-10]

im glad i saw this tread im looking to do a serp. kit for my truck and im looking for something cheap. I spent 2gs on the serp kit for my caprice but i dont want to spend that on a beater/daily driver/cruiser. what are you guys paying for these kits around where your at, im in miami and if you go to a junk yard they ask somewhere from 400-500 bucks but i think its a rip if you can find them from jegs for a tad bit more and its brand new! pcm you live in miami?

For that kind of money, you can go to Scoggin Dickey or Street and Performance and buy a new setup. I purchased a Camaro serpentine set of brackets and belt from S&P a couple years ago for about $300.00. After I added a new Edelbrock reverse rotation water pump then I was close to the $400.00

for those that don't really care weather or not they have A/C LMC sells the "dummy pulley" bracket and pulley for like $35 i think it is...it takes place of the A/C pump and pulley...

[pcmcobra]

well, you get the "benefit" of a single belt system. Which I prefer.
You can also run some later model equipment, like newer ac, and alt. Not sure if there is a benefit to that, it would all depend on how you look at it.

[East End K5]

so basically giving you only one belt to worry about then...no engine efficiency huh?

[pcmcobra]

well the efficiency I got was getting rid of clutch fan and going with some electric fans.
And I could not really tell a difference. Mine's a weekend cruiser, so efficiency is not part of my equation. Maybe some others can chime in and give you a better answer?
Good luck.

[piecesparts]

Single belt design does not really gain efficiency unless you do like pcmcobra above and loose the clutch fan. I gained at least 1 MPG with electric fans on my 91 truck (it already has a serpentine setup). The looks do improve over the older style belt systems and there is more aftermarket goodies for the serpentine setup designs. However the setback is: a broken belt and you don't go anywhere PERIOD.

Well, this is all some great information, but I still have a question in regard to the serp setup I have. It's from a 1996 S-15 Jimmy with a 4.3L V6. My problem is with the water pump.

What other year/model trucks would I be able to get a water pump that will work with the pulley that came on that truck?

It seems as though the pulley bolt pattern is a little different than what is normal & it also has the "snout" for the screw on fan that comes with those trucks.

Does anybody have an interchange for that?

Thanks,
Buddy

[Palf70Step]

Just buy the waterpump for the for a 88-94 V8. It will work.

You do have to watch the crank pulley. Some of the V6s use the same lower pulley as the V8s, some do not. I do not have the part numbers handy at the moment though.

[BAGNDRAGIT]

sorry if i missed it in the thread, does anyone know where to get the a/c delete pulley for the serpentine setup?

Thanks

[ShowSS12]

I think I read some where on page 3 that LMC dose..

[jholley]

Here is one, but I've seen them all over e-bay and elsewhere cheaper

[MylilBowTie]

Goto Rockauto.com and lookup the vehicle that your serpentine setup is from. Then look at the Heat & Air Conditioning tab then look at the A/C Compressor Bypass Pulley tab.

There will be the a/c delete pulley and for pretty cheap usually. 27.79 vs 75.49 and some of the difference is dorman vs ac delco.

Napa also sells a converstion plug sells for 25.00 with shiping.(local store had no idea what I was talking about). Ordered mine online from napa, 24.00 and some change. Part # EC80. This is the one with the resitor in it.

To answer some questions for you guys. Yes, you can get the wiring harness, but there are two different ones. If you have an alternator gauge in your cliuster then you need the one with the resistor. If you have the dummy light cluster then you will need the harnes without and the light provides the resistance. Here are a few links for some more information:

As far as the A/C questions, you can get a condensor that comes out on either side. The Firebird lines come out on the passenger side. Look for a condensor that comes out on the passenger side. My core support was designed to have the lines on either side.

I am not sure if the truck setups are the same, but I don't think that they are. I'm sure that someone on here has the answer! Good luck!!

I think they are the same, the perspective of the pic is different. Here's mine when the engine was out of the truck.

Yes, the F-body and B-body cars are different brackets from the C/K trucks. The car brackets position the accessories lower and spread apart more at the top. Personally, I do not like the looks of the car brackets.

Which ever brackets you use be prepared to scare yourself silly when you have to drill a hole in the cylinder head for one of the bracket mounting bolts, unless you are running late model cylinder heads. I know I was nervous drilling and tapping a hole in the head. I can’t remember which side I had to drill on my old 350 though.....I think it was the driver's side. Heck it has been 10 years since I did that to Zoomad's engine when it was in my truck.

Word of the wise….do not bolt the brackets to the block with 3/8 bolts. Instead, use studs in the block and either nylon lock or prevailing torque nuts to fasten the brackets to the studs. You will need to use the big long bolts in some areas of the brackets though. Basically, bolt them on just as Generous Motors did on serp equipped vehicles.

In addition to changing the thermostat housing as Zoo stated you also need to change the water pump to a reverse rotation pump as the pump spins backwards with serpentine systems.

Here are the 4 different SB serpentine bracket systems to be found in the bone yards. The 4.3L V6 used the same brackets.

1) ’87 – 91’ stamped steel brackets. These are the least desirable as they are notorious for braking causing weird noises and belt squeaks. These are junk....don't buy them (First picture)
2) ’92 – ’95 aluminum brackets. (Second picture) GM also sells these brackets in kit form. GM part number 12497698 and goes for around $700. (Third pic) The down side to these brackets is you have to use the crappy R4 A/C compressor.
3) ’96 – ’04 (yep, the 5.7L was still around in 2004) These are good brackets as well and allow for the much more reliable Delphi A4 A/C compressor. These are the best in my opinion. (Fourth pic)
4) F and B body car brackets. I have a picture of those at home that I can scan in this weekend.

[DirtyLarry]

Pieces,

The picture above your post is a B and F body TBI engine, which are not the same as truck brackets.

Once you get into the Corvette engines, TPI, LT1’s and other oddities there are some freaky brackets out there that are not worth messing with as they are too hard to find as you mentioned. Plus, they will not fit a standard small block.

Here are pictures of the car options….

They told me It has a built in resistor so it wont burn your alt up. I picked it up for less than $30 dollars. It just plugs into your old plug then into the new alternator. I got my serpentine setup off 1990 camaro TPI engine. The water pump and PS pump have to be reverse direction.(NOT REVERSE FLOW). When i started my truck for the first time I had the right WP but not the right PS pump. PS fluid was coming out the top of the pump.
