Ahh, that explains why my mechanic warned me about replacing it.
My car has the NF motor with 10:1 and the bigger valves. The belt
was also in *really* bad shape, and was off anyway getting my oil
pump replaced. So there was no labor, just $30 for the new belt.

I'm happy again (except for the bill from yesterday's work....)
