Ford Explorer Serpentine Belt Drive Component Kit Guide (1996-2001)
Everything you need to know before replacing the serpentine belt, tensioner, and pulleys on your 1996-2001 Ford Explorer.
- Always replace the entire kit (belt, tensioner, idler pulleys) at the same time to prevent repeat failures.
- A squealing noise is most often caused by a weak tensioner, not just a bad belt.
- High-quality aftermarket kits from brands like Gates or Continental offer OEM-level performance for less money.
- Verify your engine (4.0L V6 or 5.0L V8) before ordering, as the kits are different.
Is Your Explorer's Serpentine Belt System Failing?
The serpentine belt and its components are wear items. They are made of rubber and metal, constantly exposed to heat, friction, and tension. Over thousands of miles, the belt will stretch and crack, and the bearings inside the pulleys will wear out. For the 1996-2001 Ford Explorer, these parts typically last between 60,000 and 100,000 miles, but you should inspect them regularly. Ignoring the warning signs can leave you stranded.
Symptoms of a Failing Serpentine Belt Kit
- Squealing or Chirping Noises: This is the most common sign. A high-pitched squeal when you start the engine, accelerate, or turn on the A/C means the belt is slipping. This is often caused by a weak tensioner, not just a worn belt.
- Rattling or Grinding Sounds: A rattling or grinding noise from the front of the engine points to a bad bearing in the tensioner or an idler pulley. This is a clear sign that the component needs immediate replacement.
- Visible Wear or Damage: Look at the belt. If you see cracks, frayed edges, missing ribs, or a smooth, glazed appearance, it's time for a replacement. Also, check the tensioner for excessive movement or jumping while the engine is running.
- Accessory Problems: If your battery light comes on, the power steering feels stiff, or the A/C isn't blowing cold, the belt may not be turning those accessories properly.
Why You Must Replace the Whole Kit
It's tempting to save money by only replacing the squealing belt. This is a mistake. On these Explorers, the tensioner is usually the root cause of the noise. A worn tensioner can't keep proper pressure, causing even a brand-new belt to slip and wear out quickly. Replacing the belt, tensioner, and idler pulleys together ensures all components are fresh and designed to work with each other, preventing a repeat failure and saving you from doing the job twice.
Choosing the Right Aftermarket Kit: OEM vs. Aftermarket
For a 1996-2001 Ford Explorer, a high-quality aftermarket kit is a smart choice. The original Ford (Motorcraft) parts were good, but after 25+ years, modern aftermarket brands like Continental and Gates often meet or exceed those original specifications. You can get OEM-level quality without the higher dealership price tag.
- Continental & Gates Kits: Both are top-tier, Tier 1 manufacturers that supply parts directly to automakers. You can't go wrong with either brand. They both use high-quality EPDM rubber belts that resist cracking and heat, and their tensioners and pulleys are built for durability. Some mechanics have personal preferences, but both are considered excellent choices for your Explorer.
Check Your Engine
The 1996-2001 Explorer came with two main engines: the 4.0L V6 (both OHV and SOHC versions) and the 5.0L V8. These engines use different belts and component kits. Always verify your engine size before ordering to ensure you get the correct parts.

Frequently Asked Questions
Can I drive my Explorer with a bad serpentine belt?
It is not recommended. A slipping belt can fail completely at any moment. When it breaks, you will lose power steering, the alternator will stop charging the battery, and the water pump will stop circulating coolant, leading to rapid engine overheating and severe damage. If you hear squealing or see a battery light, get it fixed as soon as possible.
Are there any recalls on the serpentine belt system for this Explorer?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or major technical service bulletins (TSBs) for the serpentine belt, tensioner, or pulleys on the 1996-2001 Ford Explorer. Failures are typically due to normal age and wear.
Is replacing the serpentine belt kit a good DIY job?
Yes, for a mechanically inclined person. The job requires basic hand tools, including a ratchet set and a 3/8-inch drive ratchet or serpentine belt tool to release the tensioner. Access is a bit tight, but it can be done from the top of the engine bay. Always make a diagram or take a picture of the belt routing before you start.
How do I release the belt tensioner on my Explorer?
The automatic belt tensioner has a square hole that fits a standard 3/8-inch drive ratchet or breaker bar. Insert the drive and rotate it to loosen the tension on the belt (clockwise for 4.0L/5.0L engines). This will allow you to slip the old belt off the pulleys. When installing the new belt, you'll do the same to get the belt over the final pulley.
