I have a 2005 Sienna with only 52700 miles on itI have never replaced the timing belt in this vehicle as there is still a long way to go to the mileage based replacement which is 90k I think. That said, this vehicle is now 18 years old with its original timing belt.
Should I wait until I hit 90k, which will probably be at least another 4 years, or should it be replaced due to age ?
Thanks !
