I imagine the engine light is due to the harmonic balancer being out (best guess until I get it read) or possibly when the belt was squealing and running slow .. another system was affected and popped the light on.

Plausible?

I don't know what a Saab harmonic balancer looks like, but if something like this is going on, then yeah, you could be right.

yup, it is very similar. The key is that if belts are breaking in succession, something is obviously either ceasing or causing the belt to grind down... I think this is more likely than anything ceasing since the a/c compressor is new and the alternator light isn't coming on and the power steering pump and water pump are RARE items to cease on that car... especially when it only has 70k miles on it.

If this isn't the problem, I am thinking water pump is next most likely... but so far, no heat issues being reported.
