NISSAN Belt Tensioner/Pulley - 21051MA70A

This NISSAN Belt Tensioner/Pulley, part number 21051MA70A, is a critical component for your vehicle's accessory drive system. It plays a vital role in maintaining the correct tension on your serpentine belt, which powers essential components like the alternator, power steering pump, and air conditioning compressor. Proper belt tension is crucial for the efficient operation of these accessories. A worn or faulty tensioner can lead to a loose belt, causing slipping, noise, and reduced performance of the driven components. In severe cases, a failing tensioner can even cause the belt to break, leading to a complete loss of power steering, charging, and cooling. Crafted with high-quality materials and engineered to NISSAN's exacting standards, this tensioner/pulley assembly offers durability and consistent performance. Replacing your belt tensioner at recommended intervals or when signs of wear appear can prevent costly damage to other engine parts and ensure your NISSAN continues to run smoothly and reliably.
