timing belt question on vvt-i engine

[tef]

I understand a 1mz-fe vvt-i engine is interference. If that is the case is there anything I should be concerned about that is different from a regular 1mz-fe engine when changing the timing belt? Thanks

I would have the crank and cams line up to the timing marks before removing the belt. I made the mistake of removing the timing belt on a Nissan which was an interference engine and I had to spend a while to turn both the crank and cam in sync to prevent valve damage. Also disconnect the battery to prevent accidental start-up. Other than that, include the basic service like water pump, idler, and maybe seals.
