This MITSUBISHI Belt Tensioner/Pulley, part number 1345A078, is engineered to maintain the correct tension on your vehicle's serpentine belt. Proper belt tension is crucial for the efficient operation of accessories such as the alternator, power steering pump, and air conditioning compressor. Over time, belt tensioners can wear out, leading to a loose belt, which can cause slipping, noise, and reduced functionality of driven components. Replacing a worn tensioner with this genuine MITSUBISHI part helps prevent premature belt wear and ensures all accessories receive the proper drive power. Crafted with high-quality materials, this tensioner pulley is built for durability and long-lasting performance, meeting the stringent standards set by MITSUBISHI. Installation is designed to be straightforward, ensuring a proper fit for your specific MITSUBISHI model.
