I know very little about motor vehicle maintenance and repair, so please forgive me if this is a stupid question.
Recently my car started making a puttering sound ("puh-puh-puh..."). I took it to the Toyota dealer, and they said it sounds like it's coming from the timing belt, but I didn't ask them to fix it because I wanted to do more research on this problem. I have a 2005 Toyota Camry with 60,000 miles. The manual says to get the timing belt replaced at 90,000 miles.
Should I get the timing belt replaced, or should it be fine until around 90,000 miles?
