How Many Miles does Last Serpentine Belts 4Runner

[hgarcia]

My 4Runner 3rz-fe 2.7L has about 206,000 miles today.

I did replace the belts from 150,000 miles its OEM from Toyota on 12/6/2011

My question is how many miles does it last

BELT, V-RIBBED
9091602336

BELT,V,VANE PUMP
993642111083

BELT,V COMPRESSOR
993642091083


Or do I need to replaced it because I will drive to the desert next month about 3,000 mile trip round trip to Mexico.

I almost finish with the job.

That is one thing that you can just run til it breaks. Even more so on a truck with multiple belts. You could always carry spares for your trip, but even in Mexico it is a common item.

Belts can last a long time and fail unpredictability. 50,000 mi is really not much.

My wife's expedition is on original belt. 160k miles.

My factory alt. belt was failing when I changed mine at 120k with the timing belt. No amount of tightening would stop it from squealing. The other two were fine.

Not sure at all, but I think the Toyota one might be original since the likely hood of the previous owner to have paid for an OEM belt over a parts store belt — is extremely unlikely.

If original, it's got over 400,000 on it.
