- For a complete repair, it is highly recommended to replace the belt tensioner at the same time as the belt.

- Quality aftermarket brands like ACDelco, Bando, and Mitsuboshi offer excellent value and reliability.
Is Your Accessory Drive Belt Failing?
An accessory drive belt is a wear item, meaning it will eventually need replacement. For the 2007-2012 Ford Taurus, the signs of a worn-out belt are usually easy to spot. Ignoring them can lead to a breakdown, as a snapped belt will instantly disable key systems.
Common Failure Symptoms:
- Squealing or Chirping Noises: This is the most frequent symptom. A high-pitched squeal, especially when you first start the engine or turn on the A/C, usually means the belt is slipping because it's worn, stretched, or loose.
- Visible Damage: A visual inspection can reveal a lot. Look for cracks, frayed edges, missing chunks of the ribs, or a shiny, glazed surface on the belt. Any of these signs mean the belt's integrity is compromised and it should be replaced.
- Accessory or Electrical Problems: If the belt slips or breaks, the components it powers will stop working. You might notice the battery warning light coming on (alternator failure), the steering becoming very heavy and difficult to turn (power steering pump failure), or the A/C blowing warm air.
- Grinding or Rumbling Sounds: While the belt itself can make noise, a grinding or rumbling sound often points to a failing bearing in the belt tensioner or an idler pulley. If you hear this, the tensioner assembly should be inspected and likely replaced along with the belt. 🎬 Watch: How to replace the belt idler and tensioner assembly.
Pro Tip: Replace the Tensioner and Idler Pulley
The most common issue related to the drive belt system on this generation of Taurus is not the belt itself, but the failure of the belt tensioner and idler pulley. A weak tensioner can't keep the belt tight, causing noise and premature wear on a new belt. It is highly recommended to replace the belt tensioner assembly at the same time as the accessory drive belt for a complete and lasting repair. The tensioner is held on by three 8mm bolts and is a common point of failure.

For a straightforward wear item like an accessory drive belt, a quality aftermarket part offers performance and reliability that is comparable to the original equipment (OEM) part, often at a better price. The key is to choose a reputable brand.
- Good: Brands like ACDelco are well-regarded in the aftermarket. While known as an OEM supplier for GM, their parts are built to high standards and are a reliable choice for your Ford.
- Better: Bando and Mitsuboshi are major OEM suppliers for many Japanese automakers and have a strong reputation for quality and durability in the aftermarket. They are considered top-shelf brands by many technicians.
Ultimately, choosing a belt from ACDelco, Bando, or Mitsuboshi will provide excellent service life. Other premium brands like Gates and Dayco are also trusted choices for this vehicle.

Frequently Asked Questions (FAQ)
How often should the accessory drive belt be replaced?
Most modern serpentine belts last between 60,000 and 100,000 miles. However, it's best to inspect the belt for signs of wear like cracks or fraying at every oil change and replace it as soon as these signs appear, regardless of mileage.
Is there a recall for the accessory drive belt on this Taurus?
No, as of early 2026, there are no specific recalls from the National Highway Traffic Safety Administration (NHTSA) for the accessory drive belt or tensioner on the 2007-2012 Ford Taurus.
What happens if the belt breaks while driving?
If the belt breaks, you will immediately lose power steering, making the car very difficult to steer. The alternator will also stop charging the battery, and the battery warning light will illuminate on your dashboard. You should pull over to a safe location as quickly as possible and shut off the engine to prevent further issues.
Is replacing the accessory belt a good DIY job?
Yes, for someone with basic mechanical skills and tools, this is a manageable DIY job. Access requires removing the coolant overflow tank, but the process mainly involves using a long-handled 3/8" ratchet or a serpentine belt tool to release the tensioner, slipping the old belt off, and routing the new one. 🎬 Watch this step-by-step guide to replacing the serpentine belt. Always make a diagram or take a picture of the belt routing before you start.
