I'm impressed it just took me 3 days to do a timing belt on a 2006 Sequoia working in the afternoons. Quick question, did you use RTV sealant on both sides of the gasket for the water pump?
I used this kit:

No RTV, and so far, no leaks.
I also completely removed the radiator to give me a little more room and to avoid damaging it. Then I protected the AC coils with a couple layers of cardboard box.
Biggest PITA was breaking the crankshaft pulley bolt loose. I used the starter bump method, but as soon as the starter hits turn the key to full OFF; if you just release it, the computer will keep cranking it over.
Second biggest PITA was breaking the bolts loose between the fan and fan clutch. You just have to find a screw driver big enough to wedge between two different bolts to hold against the force of the wrench.
Everything else was pretty straight forward. After reassembling she started right up and ran smooth as a top.
The old belt looked absolutely pristine. But it's worth the peace of mind to have the new one on there.
