I have a '98 s10 4cyl manual (without factory A/C), and the power steering and the mechanical fan were not watching their backs. It is pretty simple to use a short belt to run just the alternator and waterpump. Not sure how this would work with A/C, you'd probably have to quit that bad habit at the same time too...

Remove the fan, but put the fan pulley back on for use as an idler pulley. grind away a little bit under the thermostat housing for clearance to the belt. In the direction of belt travel: Belt comes off the crank, around the idler and alternator as before. then over the top of the fan pulley (this is where you needed the clearance), originally went under the fan pulley. And back down to the crank, the water pump is driven from the back side of the belt between the fan pulley and the crank. The water pump is still driven in the normal rotation, the fan pulley turns opposite so you probably want the mech fan removed.

What's it worth, I don't know, it's directionally correct, I've moved on...

I did put an electric fan on, but have never used it because I didn't finish wiring in a thermostatic switch, and it is not required the way I drive. With normal practices discussed here, (turn off engine while coasting or stopped). I should have not bothered putting in the fan. Anyone want an elec fan from a v6 camaro, with a couple aluminum angle pieces to fit in a 4cyl s10? 20$ ? I've never towed anything, but I have had it like this for about 15 months and never seems to be an issue.

The steering is obviously not great for parking lots, but really it's much better otherwise, the steering does not change assist as you start & stop the engine.
