Chrysler Cirrus Serpentine and Accessory Drive Belt Guide (1995-2000)
Don't get stranded; learn the critical differences between belts for the 2.4L and 2.5L engines.
- You MUST know if you have the 2.4L I4 (one belt) or 2.5L V6 (two belts) before ordering.
- A squealing noise is your final warning before the belt breaks; inspect it immediately.
- For a complete repair, replace the belt tensioner(s) and idler pulleys along with the belt(s).
- Top aftermarket brands like Gates, Continental, and Dayco offer excellent quality and value.
The Most Common Mistake: 2.4L vs. 2.5L Engines
Before you buy any parts, you must identify your engine. The 1995-2000 Chrysler Cirrus used two different engines with completely different belt systems.
- 2.4L 4-Cylinder: This engine uses a single serpentine belt to run all accessories.
- 2.5L V6: This engine uses two separate belts. One main accessory belt drives the alternator and A/C, while a second, separate belt drives only the power steering pump. If you own the V6, you should inspect and likely replace both belts at the same time.
Symptoms of a Failing Serpentine Belt
A belt rarely fails without warning. Listen and look for these signs at every oil change to avoid a sudden breakdown.
- Squealing or Chirping Sounds: This is the most common symptom. A high-pitched noise from the engine bay, especially when starting the car, accelerating, or turning on the A/C, usually means the belt is slipping.
- Visible Cracks and Damage: Look at the ribbed side of the belt. If you see multiple cracks, fraying edges, missing chunks, or a glossy, smooth appearance, the belt is old and needs immediate replacement.
- Accessory Failure: If your battery light comes on, the power steering feels heavy and difficult to turn, or the A/C stops blowing cold, the belt may be too loose or has already broken.
Choosing the Right Aftermarket Belt
For a part like this, OEM Mopar belts offer no significant advantage in quality over top-tier aftermarket brands, yet they often cost more. You can get excellent, reliable performance from a trusted aftermarket brand.
- Premium Brands (Gates, Continental): These brands are widely trusted by professional mechanics and DIYers alike. They often use advanced EPDM rubber compounds that resist cracking and heat better than older neoprene belts. Continental's "Elite" series (formerly Goodyear Gatorback) is known for its quiet operation.
- Quality OE-Style Brands (Dayco): Dayco is a major OEM supplier and is considered a very solid, reliable choice for a standard replacement. Many mechanics consider Dayco, Gates, and Continental to be on the same level for quality and reliability.

Frequently Asked Questions
How often should I replace the serpentine belt on my Cirrus?
There is no exact mileage, but a general guideline is to inspect the belt at every oil change and plan for replacement every 60,000 to 90,000 miles, or as soon as you notice any signs of wear like cracking or squealing.
Can I drive with a squealing belt?
You can, but it's a clear warning that the belt is failing. A squealing belt is slipping, meaning your accessories (especially the alternator and power steering) are not getting consistent power. The belt could break at any moment, so it should be addressed as soon as possible.
Is this a difficult DIY job?
For a mechanically inclined person with the right tools, this is a very manageable job. The replacement typically involves removing the passenger-side front wheel and splash shield for access. The key is understanding how to release the tension from the belt tensioner, which can be either spring-loaded or a manual bolt-and-locknut style.
My A/C compressor is seized. Can I bypass it with a shorter belt?
While sometimes possible on other vehicles, official service manuals for the Cirrus do not provide a part number or routing diagram for bypassing the A/C compressor. Doing so would require measuring with a string and finding a custom-length belt, which can be unreliable. The proper fix is to replace the seized compressor.
