This GATES V-Ribbed Belt Tensioner Pulley, part code T36384, is designed to maintain the correct tension on your vehicle's V-ribbed belt.

A worn or improperly tensioned belt can cause noise, overheating, and a loss of functionality in critical systems. Crafted with quality materials, the T36384 pulley is built for durability and reliable performance. It is a direct fit replacement, designed to meet or exceed original equipment specifications for your vehicle. Regular inspection and replacement of tensioner pulleys are recommended as part of routine maintenance to ensure the overall health of your engine's accessory drive system.
