I’ve owed 3 Toyota’s with 4
I’ve owed 3 Toyota’s with 4.7s in them and one with 5.7 now. I got over 330k miles on all of them. Your 06 has a timing belt. It should be changed every 100k miles. Plus while they are chasing the belt I would suggest putting a new water pump it at the same time. It’s no more extra work while your doing the timing belt. FYI. All of the 4.7 that I had are still being driven by my Dad and my children. I couldn’t tell you how many miles are on them now. But I know they still have had no major issues yet either.
