when should timing belt be changed

timing belts on your vehicle are at 90000.0 k miles and it is good to have the water pump done at the same time due to the fact it is driven by the timing belt also the cam and crank seals should be inspected as well...its and expensive job very labor intensive...about 7.2 hrs plus the a/c needs to be recovered and recharged so the lines can be moved out of the way...also the mounts should be inspected when removed

If you look in your owners manual, it will give you the time to change in the scheduled maintenance section. Js08016 is correct but some cars differ, though 60,000 is average.

Hi the 90,000 miles is from the owners manual for 2006 PT Curiser

What are the signs one needs to be replaced
