Is the dual belt addition worth the effort?
It seems I'm in for a bunch of wrench time in the near future and planned to replace the alternator belt while I had the fan off. Alternator belts don't last real long in my service and it is tough to balance the load between the alternator and PS belts.

Yes, The dual belt is worth the minor cost of doing the replacement. Get two new belts at the same time. I was very lucky and the 2 belts that I bought has the same lot number embrossed/printed on the belt. Crank the PS pump all the way out, and adjust by using the Alternator adjustment. Killed the squeal caused by belt slippage.

G'day,
Yes.
I was always retensioning the alternator belt, tried different belts, not much difference.
Last year I threw a belt with still 150 odd miles to my destination. Not wanting to deal with a hot engine,
I connected the house batteries to the solar system and drove on, I could leave replacing the belt untill the next day.
Now I have two belts, no adjustment no squealing and all for 45 mins work.

For the price of a pulley and a 2 belts, why not do it. If you do not like it, It is reversible by simply installing the old belts. No need to replace the pulley. My local AutoZone had the double pulleys under the counter. They swapped it on to my rebuilt alternator for free. Belts were $5.00 or $6.00 a piece. Just get two with the same lot number which is written on the outside of the belts.
Oh yes, a single broken belt will not strand you along the highway.

I've been very happy with my double pulley system. If I don't have to deal with a broken belt on the side of the road, it's good for me.
Then again, I'm a belt and suspenders kind of guy!
