Timing Belt Troubleshooting Guide
When a timing belt fails prematurely, it is important to determine why it failed, so that corrective action can be taken. In most cases, the cause of the failure can be found in a problem with one of the drive components.
If the belt has to be removed for any reason, a new belt should be installed. Never refit a used belt. The following guide, developed by Gates engineers, assists in spotting problems and correcting them.
