    I have never read anything relating to a timing belt needing to be replaced due to age. I call rubbish. I would be suspect of anything that particular dealer suggests. This is just my opinion, get others.

    It's not rubbish. Just like tires, belts have a lifespan based on age and mileage...whichever comes first.
    My parents (both were mechanics) always suggested replacing timing belt at 7 years.

    I forgot whether the 4.7 is interference (I shouldn't, there's one on my 4R) but if it is, I'd never take the risk. It would be a shame to eff up that low mileage '06 engine by punting a valve through a piston.

    So my vote is to change...

    The 2UZ is indeed an interference engine.

    Yessir.
    I will say that Toyota is pretty intelligent with interference/non-interference and chain/belt. The vast majority of their interference engines are timing chains. The only one I can think of as the exception to this in the last 10 years is the 2UZ.

    LOL, I can't fault your analogy between the belt and tires. I suppose that if a person were accumulating between 12/15k miles a year, that would align with approximately the recommended mileage suggested for a T-belt replacement. I've never noticed it in print though. I suppose that if someone had asked if they should consider changing the T-belt on a 70k mile vehicle that hasn't been run for five years, I likely would've replied otherwise. But say the owner drove the vehicle only 500 miles a month, regularly; might that give you pause? Not to go off on too much of a tangent, the scenario is simply wandering around in my head.

    I'd still replace it. Rubber breaks down with age. Breaks down even faster if it comes in contact with oils or solvents.

    I would recommend changing it and the pump. Best to hit it before you throw a rod.

    How could a timing belt cause you to "throw a rod"?

    2uzfe is a interference engine.

    Belt breaks at high rpm things break fast... Plus the 2uz is cast rods not forged so the rods are weak...
