    Next month I'll be due for my second timing belt replacement - I replaced it last in June '16 at 168k, currently at 180k (yes, 12k miles in 9 years). I'm pondering two things:
    - Radiator was replaced with Denso at last timing belt change. Should I replace it again? It still looks like new.
    - If the cam and crank seals aren't leaking, replace them or leave them alone?

    If it were me, I'd probably roll a full 10yrs on the belt, but I'd inspect it for sure.

    If you're in there, I'd do the cam and crank seals.

    I wouldn't replace the radiator, 12k miles on a radiator to replace it seems silly.

    I'm gonna hit 9 years next April but I'm nowhere close to 90k miles. I'm considering pushing the belt to 10 years. I looked at it when I replaced my alternator and it still looked good.

    I still have the belt I replaced 9 years ago and even that looks good still, though sitting in a drawer isn't terribly demanding of it.

    Replacing per schedule it gives me peace of mind when I'm sitting at 4k rpms pulling the camper up a long hill

    My general rule of thumb on every vehicle I've owned prior with timing belt is 100k miles.

    I get that Toyota says 9yr/90k, but I don't feel like 10yr/100k miles is pushing it if you use OEM parts, and are replacing the tensioner and pulleys Aisin includes in their kit, along with the water pump and t-stat.

    Definitely, as long as you know for sure when the belt was last done and inspect it at the 9yr/90k mark.
    That said, in the long run it doesn't really save any money or work to do it at 9/90 vs 10/100.

    Putting this here in case anyone else thinks 'I don't need the crank pulley holder tool 'cause I have an impact', and then gets to reinstalling the crank pulley and has second thoughts about snugging it down with an impact rather than torquing to spec.
    I wish I remembered how I did this last time, I don't own the tool (ordered one but it didn't show up in time) and I don't remember renting one...
    Anyway, take an old serpentine belt (must be old, it will be ruined) and wrap it around the crank pulley, then use a large pry bar to hold it against the crossmember.
    I don't think this will work for loosening the bolt, you can really feel the belt stretch and it's a tad sketchy, but it works.

    I used same technique to torque the harmonic balancer on my daughter Escape. Old belt is going in trash anyway.
