    Who\'s converted to serpintine system?

    JUst curious who here has converted to the serpintine belt system on their truck...I was pondering the idea and wanted to know if you felt it was worth the expense and what advantages/improvement have you noticed?

    Thanks

    Chris

    If you can get it cheap, go for it! Real nice. I had a line on a set up last summer, but waited to long and lost it. Will still do it someday though.

    I'm fully serpentine on my '79 with a TPI top end and IROC serpentine setup off a '90 on my 406 motor. NIce setup, only need one belt (and yeah, I guess that means if that belt goes you are done). Pics below...........It was worth it to me as I spent $150 for the full setup including all the accessories to include a '98 AC compressor. Used my Wrangler NW alternator and converted its nose piece over to the serpentine.

    Don't forget to change the water pump and fan also. They both spin the opposite direction with the factory serpentine setups. I personally wouldn't bother to convert it, because I've been stranded by a seized alternator bearing on a serpentine equipped engine. [​IMG]

    Re: Who\'s converted to serpintine system?

    i cant see the benefits of it? i got 1 belt for the alternator, and one for the power steering. what is the man reason to convert??? i think it'd be tought to power my soon to come air compressor, and where do you put the tensioner?

    beligerence doesn't justify intelligence.

    I just changed to the GM kit which is about 300 with the water pump. Reuse the PS pump even have the onboard air driven off the same belt.

    Re: Who\'s converted to serpintine system?

    ALthough it is not the REAL serpentine like the GM one, I installed a complete March Performance "serpentine" system. The advantages are that NOTHING slips, ever and it is super easy to adjust. Also it looks cool. I wanted that GM system but both the dealer and the 4x shop I trust here in town said that they had problems with it? That would be my first choice if I had not been sort of set up to worry about it, especially if you can get it for $300.

    Had the March kit hated it. The belt never stayed tite, Little things like to change the PS pump out you have to buy a new pully for 85.00. The GM kit is much better and cheaper

    Yes, one serp around the crank, alt, and water pump, and the rest v's. The stick trucks ran a smog pump off a v, I think it only goes around the pump and water pump. Autos have no smog pump.

    I thought about converting, but will keep the v-belts since you can still get home after loosing an accesory. I had to drive home from Alamosa (~4 hours) once after loosing a power steering hose (bought a new one, but had to pull the pump to install it and didn't have time). Pulled out my knife, cut the belt off, and was on my way. On the other hand, I had to tow my buddies car one day after the alternator froze up. He pulled the belt (single serp) off at my house and had to stop halfway to his house to let the motor cool off, since the water pump wasn't turning.
