Hey
Stupid question??
Why are there two belts on the power steering pump? Just redundancy/safety issue?
Is this common practice?
thanks

I've also pondered this one. Maybe for a more balanced drive on the pully? But yes I agree probably just for redundancy.
No idea why 2 but they do last forever which is a great thing.
My thoughts have always been redundancy but perhaps the maximum load might also exceed that of one belt?

My money would be on a team of over-engineers, the likes that longer seem to be able to find employment in these plastic days. They could have built a wider, single belt, so it's not a strength-per-belt thing. I think there are two of them, each capable of this load. Having 2 of them functions as a fail-safe secondary system, but it also alleviates wear and tear to a point where they barely ever need changing.
I'm with Stan on this in regard to the fail safe aspect. These belts are the ones that turn the water pump. So if one broke you'd still have cooling abilities with just one belt until both were replaced.
