I have an 05 Rav4 with 46,500 miles on it. I have two questions one regarding the serpentine belt and the other about flushing and filling the transmissin fluid. The service department at the dealership said my serpentine belt was cracked at 39,000 miles and said it should be replaced. I got a second opinion and they said it was fine. I asked the dealorship if they could show me the cracks in the belt and they said after they replace it because they have to remove it in order to see the cracks. They told me that the mechanics routinely remove the belt (no charge) to inspect it. Does this sound plausible? The dealer did a tranny flush and fill at 29,000 miles and told me that I needed another one 18,000 miles later (less than 2 years). What do you think?
