Keep your Mustang's engine running smoothly by upgrading to an aftermarket belt tensioner. Over time, a worn belt tensioner can lead to slipping belts and impaired engine components in your Mustang. The belt tensioner keeps proper pressure against the serpentine belt to drive essential systems like the water pump, AC compressor, alternator, and more. When the tensioner loosens, you may hear grinding noises or have issues with accessory function.

Don't risk overheating or a dead battery from a loose belt. We offer Mustang belt tensioners with simple, bolt-on designs to keep your accessories functioning and your belt running quietly. A fresh tensioner lets you drive in confidence knowing your Mustang's performance won't let you down. Keep small issues from spiraling into big headaches with preventive tensioner replacement. Shop belt tensioners with pulleys and mounting hardware included for your 1985-2022 Mustang.
