What parts are needed to perform a timing belt and water pump replacement on a 1998 Toyota Avalon xls?
The service book recommends changing the timing belt (and I would recomment also changing the water pump along with it, as it will save you time and money) every 90 k miles, or roughly 144 000 km, or 72 months. I personally exchange them every 150 000 km, on both my 2006 Toyota Avalon XLS and on Lexus ES 330.
