I am having it done to my 2004 Solara. I am replacing the belt and the water pump and the tensioner if it is worn. Cost is $448 plus tax which will be about $20. So figure on $500. It needs to be done at 90,000. I waited until 101,000 miles so I was living on borrowed time. I love this car and want to do preventive maintenance to keep it huimming along. It has been the best car I ever owned.
