For safety, always disconnect battery and wear appropriate safety equipment before performing any work under the hood.
- Always install tensioner per vehicle manufacturer’s guidelines.
- Look for Original Equipment belt routing diagram located under hood or on front support panel. If unavailable, make simple sketch to aid reinstallation prior to belt removal.
- Observe the method for lifting the tensioner away from the belt. Common methods are:
- 3/8 or 1/2 inch square for an extension or breaker bar.
- If lifting square is not present, the pulley bolt is designed to be used as a lifting feature. Bolt thread will be right or left in order to not loosen during lifting. Double check socket size to ensure proper fit to bolt.
- A cast lug is utilized on some models as the lifting feature. Lifting is performed by using an open end wrench
- Be careful that wrench socket or breaker bar is properly seated and positioned to allow clearance when tensioner reaches load (end) stop. Otherwise, your hand may be pinched or the tool may be trapped.
- Lift tensioner arm in the direction away from the belt.
- Lower tensioner arm against the stop after removal of the belt.
- Tensioner is spring loaded. It can force the tensioner arm rapidly to stop position and cause personal injury or tensioner damage.
- Remove the tensioner mounting bolt and washer (if supplied) for reinstallation.
- Install new tensioner in the reverse order of removal.
- Install belt in the reverse order of removal.
Ensure the belt is properly seated in all pulley grooves and routed correctly. Be careful belt is not misaligned by one or two grooves. Start engine for 30 seconds, shut off, and recheck that the belt is seated and tracking properly.
