Accessory Drive Belt Guide for the 2002-2007 Dodge Caravan
Keep your Caravan's accessories running smoothly and quietly with the right replacement drive belt.
- For V6 models (3.3L/3.8L), consider upgrading to the aftermarket "solution kit" with grooved pulleys to prevent the belt from slipping off when wet.
- Always inspect the tensioner and idler pulley when replacing the belt. It is highly recommended to replace them as a set to prevent future noise and failure.
- Symptoms include squealing noises, visible cracks or fraying, and the failure of accessories like power steering and A/C.
- Ensure you buy the correct belt for your specific engine, as the 2.4L and V6 models use different parts.
Is Your Dodge Caravan's Accessory Belt Failing?
A worn-out accessory drive belt can cause serious problems. If you notice any of these signs, it's time to inspect your belt and tensioner.
- Squealing or Chirping Noises: A high-pitched squeal, especially when you start the engine or turn the steering wheel, is the most common symptom. This means the belt is slipping.
- Visible Damage: Look at the belt. If you see cracks, frayed edges, missing ribs, or a shiny, glazed surface, it needs to be replaced.
- Accessory Problems: If your power steering feels heavy, your A/C isn't blowing cold, or your battery light comes on, the belt may not be properly powering those components.
- Overheating Engine: On models where the belt drives the water pump, a failing belt can cause the engine to overheat quickly, which is a serious issue.
Known Issue for V6 Engines (3.3L & 3.8L)
Many owners of the 2002-2007 Caravan with the 3.3L or 3.8L V6 engine have reported an issue where the accessory belt can slip off the pulleys after driving through puddles or in heavy rain. This happens because the original smooth idler and tensioner pulleys can lose grip on the wet belt. An aftermarket "solution kit" (such as Gates 38379K) is available that replaces the smooth pulleys with grooved ones and uses a double-sided grooved belt to prevent this from happening. If you have a V6 model, upgrading to this kit is highly recommended to avoid being stranded.

When shopping for a new belt, you have options. It's critical to get the right part for your specific engine, as the 2.4L 4-cylinder and the 3.3L/3.8L V6 engines use different belts.
Pro Tip: The belt tensioner and idler pulley wear out, too. A weak tensioner is often the real cause of belt noise. It is strongly recommended to replace the belt, tensioner, and idler pulley at the same time for a complete and lasting repair.
Brand Quality Tiers
- OEM (Mopar): Mopar is the original factory part. Some owners insist on using the Mopar belt, claiming its unique non-glossy finish runs quieter on these specific vans than any aftermarket option. It's considered the benchmark for fit and quality.
- Premium Aftermarket (ACDelco, Bando): Brands like ACDelco and Bando are excellent alternatives. ACDelco is a well-respected brand known for making OE-quality parts. Bando is an OEM supplier for many car companies and their aftermarket belts are known for high quality and durability. You can trust these brands to perform well.
- Standard Aftermarket (Dayco, Gates, Continental): These are also very popular and reliable brands that meet or exceed OEM standards. Gates is well-known and even produces the "solution kit" for the V6 engine issue. Dayco and Continental are also trusted choices for daily drivers.
Accessory Drive Belt Replacement Cost
The cost can vary depending on whether you replace just the belt or the full kit with the tensioner and idler pulley, which is the recommended approach.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Belt Only | $15 - $40 |
| New Aftermarket Belt & Tensioner Kit | $50 - $120 |
| Shop Labor | $75 - $150 |
Frequently Asked Questions
Do I have to replace the tensioner with the belt?
You don't have to, but you should. The tensioner spring weakens over time, causing the exact slipping and noise you're trying to fix. The pulley bearing also wears out. Replacing them together saves you from having to do the job twice.
Is this a difficult job to do myself?
For a moderately experienced DIYer, this is a very manageable job. It typically requires basic hand tools and a serpentine belt tool (which can often be rented from auto parts stores). 🎬 Watch how to use a belt tensioner tool easily. Access is usually gained by removing the front passenger-side wheel and splash shield.
🎬 Watch this step-by-step guide to replacing your serpentine belt.What's the difference between an accessory belt and a timing belt?
The accessory belt (or serpentine belt) is visible on the side of the engine and runs external accessories. A timing belt (or chain, depending on the engine) is located inside the engine under a cover and keeps the engine's internal parts synchronized. A broken accessory belt will stop your accessories, but a broken timing belt will cause major engine damage.
Why is my new belt still squeaking?
If a new belt is squeaking, the cause is almost always something else. The most likely culprits are a weak or worn-out tensioner, a misaligned pulley, or fluid (like oil or coolant) leaking onto the belt. Don't use "belt dressing" sprays, as they can damage the rubber and make things worse.
