BTW, 60k is pretty early on the timing belt change. Typically, it's done around 100k. I like to do the water pump at that point too because you are already in there. It's not a big deal, just keep it in mind.
I'd flush the coolant and put Toyota red in, and also check the accessory belts, etc.
All of the normal baseline maintenance stuff...
The earlier models called for 60K, I know that is when my 98 was done by the Po who was a mechanic. I think the going number for the new 3.4's is around 90,000.
?? All 3.4L's (96-04) called for 90-120k belt change interval.
