Finally at 104K, it broke. Not too bad... So now I've replaced this, tires once, brakes once and some oil and air filters, but that's it.

 

Thats about average. I have seen some serp belts go 110K to 115K before shredding.

Timing belts on other Yota engines run right about the same.

I think from recall, that I saw a V-6 Camry T-Belt last 129K before lunching itself.
