It's 100% custom.

As Joshie said, it is a 100% custom conversion. I did it to my slant, search for "serpentine" and you should find two or three other posts where I have relayed everything I did to complete the conversion.

The short version: I had to fabricate a bracket, machine a water pump pulley, machine an adapter for a junkyard crank pulley, and adapt other junkyard components (alternator, automatic tensioner, and pulleys).

-S/6

I'll admit this is probably a dumb question, but what's the inherent advantage in using a spring loaded tensioner over a solid, adjustable tensioner? It seems to me a solid adjustable tensioner mated to the alternator, for example, would be both easier to fabricate and have a longer service life.

I am currently working on a serp system that leaves the alt in the stock location. It will also be able to handle multiable setups. ie- power steering A/C or none or ethier one. Crank pulley is done, Alt adapter just needs its parts welded and it will be done, water pump pulley came off a Sable and just needs the 4 holes redrilled. More info will come with pics as soon as its done.

The advantages as I see it:

1) Only one tool is needed to change the belt (3/8 breaker bar with a 9/16" socket)

2) Belt tension remains basically constant, even as the belt stretches over time.

3) That constant belt tension is in the proper range. When my friend and I were deciding on where to place the tensioner, we took into account the torque (in various positions) of the automatic tensioner, and using a belt tensioner tool, were able to position the tensioner so as to provide the proper amount of belt tension, without being too tight.

I am not set up to perform this type of fabrication. I sure hope my local machine shop doesn't rape me when i present my desires to them when they overhaul my /6.

If so does this seem feasible, i will be running a custom electric fan for the custom radiator. can i just remove the hard mounted fan and run the normal V belts until i can get everything together for a quick swap out to S belt? Not sure if this will have an adverse effect on the motor.
