Why did 98 Subaru Forester timing belt shred in 1000 miles?

The Subaru Forester timing belt should not shred in 1000 miles unless there was a problem with the belt or the installation. Some possible causes include:

- Incorrect installation: If the timing belt was not installed correctly, it could slip or become misaligned, causing it to shred.

- Defective belt: A faulty timing belt could have a weak spot that causes it to break.

- Idler pulley or tensioner failure: If the idler pulley or tensioner that keeps the timing belt in place fails, it could cause the belt to slip or break.

- Oil contamination: If the timing belt becomes contaminated with oil, it can cause it to deteriorate and break.

It's important to have the timing belt inspected and replaced according to the manufacturer's recommended maintenance schedule to avoid any potential problems.
