I drive a 2003 Camry V6. I bought the car used and am now approaching 98000 miles. I am going to have the timing belt changed. The garage I spoke to qouted me a price of about $600 and that includes doing the belt, water pump, belt tensioner and pulley. This seems like a reasonble price but my main question is whether the water pump really needs to be done. I'm just looking for some input on this issue. Thank you.
