TIMING BELT...MILEAGE or AGE...???

[VX crazy]

its been discussed and verified from Isuzu, someone posted the technical info a long time ago

protects the belt from UV rays you have to remember when driving and extended period of time heat builds up under the hood which will affect the life of the belt and everytime you start the engine forces are put on the belt going from stopped to speed. Like a lot of things it is not the regular operation that puts the worst stress on an item it is the chaging from one stage to another.

serpentine belt and timing belt two different things people! how are uv rays going to affect the timing belt which is not exposed???????????

& remember the thread on tire dry rot???

It appears that it's ozone rather than UV that is the primary contributor to dry rot.

I don't know if mine has ever been replaced. I figured it will get replaced when it breaks. I'll let ya know how that goes.

We've seen the pix. You'll be armpit deep in TN gumbo when that happens.

Man, that would suck. I actually haven't had it in anything that nasty since then. I'm not real big on trying to get all that mud out from under all the hiding places.

Back O/T: I guess losing a timing belt while on a precarious incline or other off-road situation would make things interesting. I would imagine the brakes wouldn't have a lot of holding power once the engine dies.

Stress from starting and stopping in addition to extreme heat.
