Accessory Drive Belt Guide for the 2002-2007 Jeep Wrangler TJ
Don't let a squeaky belt ruin your drive; here is what you need to know before you buy a replacement.
- The most common symptom of a failing belt is a squealing noise; do not ignore it.
- Always verify the correct belt length for your engine (2.4L or 4.0L) and A/C configuration.
- When replacing the belt, always inspect the tensioner and idler pulleys for noise or wobble.
- High-quality aftermarket brands like Bando, Mitsuboshi, and ACDelco are excellent alternatives to the more expensive Mopar part.
Is Your Jeep's Belt Trying to Tell You Something?
A failing accessory drive belt usually gives you a few warning signs before it breaks completely. Ignoring them can leave you stranded. The most common sign is a loud squealing or chirping noise coming from the engine, especially when you first start it up or on damp days. You might also 🎬 Watch: Hear what a squealing Jeep belt sounds like see visible damage on the belt itself. Look for cracks, frayed edges, missing pieces of the ribs, or a surface that looks shiny and smooth (glazing). If your power steering suddenly gets heavy, the battery light comes on, or the temperature gauge shoots up, the belt has likely already snapped.
Pro Tip: Check the Pulleys and Tensioner
When you replace your belt, always inspect the other parts it touches. With the engine off and the belt removed, spin the idler pulley and the tensioner pulley by hand. If you feel any wobble, roughness, or hear any grinding noises, they need to be replaced too. A bad pulley can destroy a new belt quickly.

For a part like the accessory drive belt, a high-quality aftermarket brand is often just as good as the original Mopar part, and sometimes even better. The key is choosing a reputable manufacturer. Here’s a breakdown of the brands available, tiered by reputation among Jeep owners and mechanics.
Tier 1: OEM or Better Quality
- Mopar: This is the original factory part. It's a reliable, high-quality choice that you can't go wrong with, though it's often the most expensive.
- Bando / Mitsuboshi: These Japanese brands are often the original equipment manufacturer for many car companies. They are known for their high quality and durability, making them an excellent choice.

Tier 2: Reputable Aftermarket
- Crown Automotive: A brand that specializes in Jeep parts. While they make parts for nearly everything on a Jeep, for a critical and inexpensive part like a belt, most experienced owners prefer to stick with a dedicated belt manufacturer from Tier 1.

Frequently Asked Questions
How often should I replace my Wrangler's accessory belt?
There is no strict replacement interval. The best practice is to inspect the belt at every oil change for signs of wear like cracks, fraying, or glazing. Generally, plan to replace it between 50,000 and 100,000 miles, but replace it sooner if it shows any signs of damage. Your driving habits, especially off-roading through mud and water, can shorten its life.
Is this a difficult job to do myself?
No, this is a great DIY job for beginners. For the 2002-2007 Wrangler, you'll have an automatic belt tensioner. You just need a 1/2-inch breaker bar or a serpentine belt tool to rotate the tensioner, which releases the tension and allows you to slip the old belt off and the new one on. The whole job usually takes less than 30 minutes.
