So I am getting around 90k and I am looking to replace my timing belt, and some other routine parts that will go along with the work. I called lexus and ordered the parts however while ordering the parts they transfer me to a tech who tells me that the timing belt is SUPER impossible for a human that doesn't work in lexus to do. 1 small error in lining up the teeth and BOOM!!! I have changed many a timing belt and even one on a 2000 LS400, is this guy just trying to get me to bring the car in or is it SUPER IMPOSSIBLE!

no ones ever done it befoe...
