My 2003 Toyota Avalon V-6 has 79,000 miles on it. Should the timing belt be replaced?
Jim, the belt is changed by miles or months and that info is in your owners manual . This thing is 15 years old and if that is the original belt you are on borrowed time now.
Agree with @VOLVO_V70 If the belt has never been changed, you are WAY overdue on time. Likely a bit overdue on mileage. Either time or mileage can fail the belt. Get it replaced NOW!
YES. “Your cost of ownership is unchanged whether you do it now or in a year. Either way you pay. Once the car is past its drivetrain warranty, you are on your own. Why not get it done a bit sooner rather than later? Remember, wait too long and the downside is huge.” More on timing belts here.
I’m curious why you don’t believe the instructions from the manufacturer here.
