Dodge Avenger Accessory Drive Belt Guide (1995-2001)
Everything you need to know about choosing the right replacement accessory drive belt for your 2.0L or 2.5L Dodge Avenger.
- You must confirm if you have the 2.0L 4-cylinder or 2.5L V6 engine before buying, as they use different belts.
- Squealing noises are the most common warning sign, but you should also visually inspect the belt for cracks and fraying.
- For best results, inspect the belt tensioner and idler pulleys and consider replacing them at the same time as the belt.
- A broken belt will make the car undrivable by causing a loss of power steering and battery charging, and may lead to engine overheating.
Engine-Specific Belts: 2.0L vs. 2.5L V6
The 1995-2001 Dodge Avenger was available with two different engines: a 2.0L 4-cylinder and a 2.5L V6. These engines use different accessory drive belts. The 2.5L V6, which was shared with Mitsubishi models, may even use two separate accessory belts. It is critical to confirm your engine size before ordering a new belt to ensure you get the correct part.
Symptoms of a Failing Accessory Drive Belt
A worn belt will give you clear warning signs. Ignoring them can leave you stranded. Look for the following symptoms:
- Squealing Noises: A high-pitched squeal or chirp, especially on startup or when the A/C is turned on, is the most common sign of a worn or slipping belt.
- Visible Damage: Inspect the belt for cracks, frayed edges, missing ribs, or a shiny, glazed surface. These are clear signs it needs replacement.
- Accessory Failure: If your headlights are dim, the battery light is on, steering becomes difficult, or the A/C stops blowing cold, the belt may be slipping or broken.
- Engine Overheating: If the belt drives the water pump, its failure can cause the engine to overheat very quickly.
A Note on Belt Tensioners
Often, a squealing noise is caused by a weak or failing belt tensioner, not the belt itself. The tensioner is a spring-loaded pulley that keeps the belt tight. If it's worn, a new belt will still slip and wear out quickly. It is highly recommended to inspect and consider replacing the tensioner and any idler pulleys when you replace the belt.
Choosing the Right Aftermarket Belt
For a vehicle of this age, aftermarket belts offer excellent quality and value. OEM parts can be difficult to find and are often more expensive. The key is to choose a reputable brand. Given the 2.5L V6 engine's Mitsubishi origins, brands that are OEM suppliers to Japanese automakers are excellent choices.
- Premium Brands (OEM Quality): Bando and Mitsuboshi are often original equipment manufacturers for Japanese vehicles and are considered top-tier choices. Their aftermarket belts are typically made to the same high standards. ACDelco is another well-regarded brand known for quality parts that meet or exceed OEM specifications.
- Standard Brands: There is no significant quality difference between the available aftermarket options for this specific part, so choosing based on price and availability is a reasonable approach.
Pro Tip: When you replace your accessory drive belt, take a picture of the belt's routing around the pulleys before you remove the old one. This will save you a lot of headaches during installation.

Frequently Asked Questions
How often should I replace my Avenger's accessory belt?
There is no strict interval. A good practice is to inspect the belt at every oil change and plan for replacement every 40,000 to 60,000 miles, or as soon as you see signs of wear like cracking or fraying.
Can I replace the accessory belt myself?
Yes, for most DIYers with basic tools, this is a relatively easy job. The main challenge is releasing the belt tensioner to get the old belt off and the new one on. The job typically takes less than an hour.
Do I need a special tool?
Maybe. Many tensioners can be moved with a standard long-handled ratchet. However, some may require a specific serpentine belt tool to get enough leverage in tight spaces.
Were there any recalls for the Dodge Avenger drive belt?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or specific technical service bulletins (TSBs) for the accessory drive belt on the 1995-2001 Dodge Avenger.
My 2.5L V6 has two belts. Should I replace both?
Yes. If your Avenger has two separate accessory drive belts, it is best practice to replace them both at the same time. They have been exposed to the same heat and wear for the same amount of time.
