If I had to guess the belt will start to slip long before it breaks. So if it feels like you don't have as much top end power or it has less boost. That would be the time for a new belt. I have run some very old belts. I can't think of one that broke. I would guess you could get 10 years 100,000 miles out of the belt with out failure. Slip may occur before then.

If that is the case Einstein, can you explain to me how the blower belt keeps the cams from turning?

In the belt diagram earlier, it looks like a regular accessories drive system, and external WITHOUT COGGS.
Most OHC are now Chain Driven.
The OHC engines that I have worked with, the timing belt ONLY Drives the cam, exception, as mentioned a OLD Vega, the back side of the belt, drove the water pump and radiator fan.
I could be Wrong.....

On SOME engines, the single serpentine belt runs EVERYTHING. In the 70's I drove a Pontiac Astre - essentially a Vega with a split grille and gunslit tailllights. The inline 4 was overhead cam and when the serpentine belt finally broke the camshaft stopped, and the crank kept turning for a few more revolutions. No bueno.Previously HoosierL98GTA
