Genuine Nissan Auto Belt Tensioner - Nissan Navara D40 2010+ & Pathfinder R51 2010+

This is a Genuine Nissan automatic belt tensioner to suit Spanish-built (VSK) Nissan Navara D40 and Pathfinder R51 models fitted with the YD25 engine from January 2010 onwards. Located at the front of the engine, it applies constant spring-loaded pressure to the main accessory drive belt. This is essential for the correct operation of the alternator, power steering pump, and air conditioning compressor. Please note, this automatic tensioner is not interchangeable with the manual idler pulley setup found on models prior to 01/2010.

A worn tensioner can cause significant issues, as the internal spring weakens or the pulley bearing fails over time. Symptoms of a failing tensioner include a squealing or noisy drive belt (especially on startup), reduced power steering assistance, and flickering battery lights due to the alternator not being driven correctly. Replacing a faulty tensioner is critical to prevent the drive belt from coming off, which would cause an immediate loss of power steering and water pump function.

Product Features

• Genuine Nissan Quality: Guarantees perfect fitment, performance, and long service life, unlike inferior aftermarket alternatives.
• Maintains Correct Tension: A precisely calibrated internal spring ensures the drive belt operates without slipping, protecting your engine's vital accessories.
• Durable Construction: Engineered with high-quality materials and a robust pulley bearing designed to withstand the tough Australian climate and off-road conditions.
• Prevent Catastrophic Failure: Using a genuine part eliminates the risk of premature failure common with cheap tensioners, which can throw a belt and cause sudden loss of power steering and engine cooling.

Installation Notes

This is a straightforward replacement for an experienced home mechanic or a qualified workshop. Access is at the front of the engine bay and requires a basic set of hand tools to release the old tensioner and install the new one. It is highly recommended to replace the main drive belt at the same time as the tensioner. You should also inspect any idler pulleys for signs of wear or noise.
