What does an accessory belt tensioner do?

The accessory belt tensioner applies constant pressure to the serpentine belt. This ensures the belt grips the pulleys firmly, preventing slippage and keeping your vehicle's accessories like the alternator, A/C compressor, and power steering pump running correctly.

When should I replace my belt tensioner?

You should consider replacing the tensioner if you hear squealing noises from the belt area, notice excessive belt movement or wobble, or if the tensioner itself appears damaged or worn. It's often replaced along with the serpentine belt.

Does this tensioner come with a new serpentine belt?

This product is for the belt tensioner only. The serpentine belt is sold separately and should be checked for wear and replaced if necessary.

Product Details

When you open the hood of your 2008-2010 Ford F-250 Super Duty with the 6.4L diesel engine, you'll find this Gates belt tensioner. It's a key part of your accessory drive system, which powers things like your air conditioning, power steering pump, and alternator. This tensioner's job is to apply the right amount of pressure to the serpentine belt, ensuring it grips the pulleys smoothly and doesn't slip.

A worn-out tensioner can lead to a noisy belt, or worse, cause the belt to slip or even break, leaving you without essential accessories. Gates is a well-known name in belts and related components, and this tensioner is built to keep your accessory drive running as it should. It's designed to fit right on your specific Super Duty, making it a straightforward replacement when the time comes.

Replacing a belt tensioner is often done when you're replacing the serpentine belt itself, especially if you notice any squealing or excessive movement in the belt. This Gates tensioner is a solid option to get your truck's accessory drive back in reliable working order.
