Gates 11-20 Ford F Series V-6 3.5L A.C. Stretch Fit V-Ribbed Belt

This Gates K040359SF V-ribbed belt is specifically designed as a stretch-fit accessory belt for the 3.5L V-6 engine found in 2011-2017 Ford F-150 trucks. Unlike traditional tensioner belts, this design uses the belt's own elasticity to maintain proper tension, simplifying installation by eliminating the need for a separate tensioner assembly. This makes it a straightforward replacement for maintaining your engine's accessory drive system, ensuring your alternator, power steering pump, and A/C compressor operate correctly.

Gates uses a durable rubber compound for the belt's construction, which is formulated to resist heat and cracking, common issues that lead to premature belt failure. The V-ribbed design ensures a solid grip on the pulleys, preventing slippage even under load. Because it's a stretch-fit belt, proper installation is key; it's designed to be installed with the engine off and then allowed to seat itself as the engine runs. This type of belt is a popular choice for applications where space is tight or a traditional tensioner isn't feasible.
