NEW THREAD !!



This discussion was originally started under the "Cad 500 Serpentine Belt"
thread.

To keep both discussions on topic, I've started over.







I'm looking for feedback from those of you who have done a serpentine belt
conversion on their 455. Pros & cons. I've heard that some have taken the
serpentine setup off due to problems. What where the problems?

I want to upgrade to a CS130D alternator, Sanden type A/C compressor, and a
newer PS pump with a hydroboost return port. These accessories can easily be
found used in the men's malls and most come with serpentine pulleys
nowadays. Doing a serpentine conversion might reduce the overall difficulty
in finding suitable accessories. Custom brackets will no doubt be required,
but I'm good at that.

I am also curious if anyone has done a serpentine conversion that spins the
water pump & fan in the original direction? I'd prefer this simply so that
replacement waterpumps are easier to find. I don't want to have to look for
another fan or special water pump.

What crank & water pump pulleys are being used? What tensioner? Knowing this
info would save me a bit of time in looking for suitable donor parts.




Thanks,
