My 2001 has 75K but I bought it in 2000. Any thoughts on doing the timing belt early at 75K since it has seven years?

It won't hurt anything, I say if you have the cash and want to do it go for it. I don't think it's necessary though.

I'd get it done just because of the age. You're gonna have to do it eventually. FYI I just passed 173k miles and did my second waterpump/timing belt service last week. Saw the belt from the first change and it looked like it was on it's way out. I saw a few barely visible cracks on the outside edges of the belt about 1/4" in length. you couldn't really see them unless you folded the belt a bit and were really looking for it. I'm just glad I got it done...I was told if you live in an area like mine that can get really cold the belt is more susceptible to cracking and eventually failing as opposed to more temperate environments. But, a 7 year belt sounds iffy to me.

I was wondering the same thing on my rig. 2000 and I just flipped 65K. At this rate it's going to take a quite a few more years for me to hit 90K. I'm thinking I don't want to risk it.

is the 3.4 an interference motor. If it isn't just run it till you're at 90k.

If you use a genuine timing belt, and change the waterpump, thermostat and both bearings, you're good to go for at least 90k. I've done so many of them at ~200,000km (125k) to know that 90k (150,000km) intervals are actually conservative with the 3.4L engines.

YMMV

ps, almost all Toyota t-belt equipped engines are non interference. Almost all chain-drive engines are interference.

Notable exceptions for T-belt engines:
jdm engines in some uber cars (95+ 4AGE, 3SGE, etc)
recent 3.3L sienna/camry/highlander/ES330/RX330 etc

My 2000 is at 57k miles. I'm contemplating having it changed. Since it's not actually an interference engine I'm not that worried about. I just had the timing belt changed on my 1998 Honda Prelude with only 40k miles because of the age of the belt and tensioner. The difference is that on the Prelude a broken timing belt means a new engine.
