I was looking at the maintenance schedule for my car and noticed Mazda doesn't have a recommendation for replacing the serpentine belt. They just recommend inspecting it every so often. That seems imprudent to me.
Interestingly, they recommend 10 years/120k miles for coolant but only 75k for plugs.
