Maintain secure and reliable belt tensioner fitment with this Genuine Nissan Tensioner Bolt, designed for Nissan Navara and Pathfinder models fitted with the YD25 diesel engine. This OEM fastener secures the belt tensioner assembly in position, helping maintain correct alignment and reliable operation of the engine accessory drive system.

Tensioner bolts are exposed to engine vibration, heat, mechanical loads, and constant belt tension. Over time, bolts can become worn, stretched, corroded, or damaged, particularly when components have been repeatedly removed and refitted. A damaged or incorrectly fitted tensioner bolt can affect the secure mounting and alignment of the tensioner, potentially contributing to belt noise, vibration, or premature belt and pulley wear.

Manufactured to Genuine Nissan specifications, this tensioner bolt is designed for the correct dimensions, strength, and fitment required for the engine's belt tensioner assembly. It is an ideal replacement when servicing the accessory drive system, replacing a tensioner, or restoring your Nissan YD25 engine to factory condition.
