OEM Timing Belt Tensioner Spring for 1996-2002 Nissan Pathfinder models equipped the VG33E powertrain. 

The Timing Belt Tensioner Spring is a component of the engine's timing system that applies tension to the timing belt to keep it properly aligned and functioning. Over time, the tensioner spring can become worn or damaged, which can lead to serious engine problems.

Some signs that the Timing Belt Tensioner Spring may need to be replaced include:

• Whining or rattling noise: If the tensioner spring becomes worn or damaged, it can cause the timing belt to become loose or misaligned, which can lead to whining or rattling noises coming from the engine.
• Tensioner pulley movement: If the tensioner spring is worn, it may not be able to keep the tensioner pulley in the correct position, leading to excessive movement or slack in the timing belt.
• Difficulty starting the engine: A worn or damaged tensioner spring can cause the timing belt to slip or become misaligned, leading to difficulty starting the engine or the engine stalling.
• Visible damage: If the tensioner spring appears worn or damaged, such as being bent, cracked or broken, it may need to be replaced.

Additionally, if the timing belt is being replaced, it is a good idea to replace the tensioner spring at the same time.
