Everyday Usage of the Serpentine Belt in Your 2008 Acura MDX
The serpentine belt in your 2008 Acura MDX is a critical, multi-purpose component. It drives several engine accessories from a single, continuous loop. In daily operation, your serpentine belt:
- Powers the alternator, which charges your battery and electrical systems.
- Runs the power steering pump, providing smooth, responsive steering.
- Drives the air conditioning compressor for cool air.
- Powers the water pump (where applicable), helping regulate engine temperature.
If this belt fails, multiple vehicle systems can simultaneously lose function, leading to breakdown or engine overheating. That’s why regular inspection and timely replacement with a quality belt is essential for safe, reliable driving.
Benefits of Using a Genuine or High-Quality Serpentine Belt
Investing in a genuine or high-quality serpentine belt provides several clear advantages:
- Exact Fit: OEM belts, such as the Mitsuboshi or Bando, are designed with precise specifications for tension, length, and rib shape. This guarantees proper function and a snug fit, reducing the risk of slippage or premature wear.
- Superior Durability: High-quality EPDM (Ethylene Propylene Diene Monomer) compound materials resist cracking, fraying, and elongation—common issues with lower-grade belts.
- Reduced Noise: A proper-fitting belt minimizes chirping or squealing, ensuring quieter rides.
- Longevity: Genuine belts can last 60,000–100,000 miles under normal use with proper maintenance.
- Warranty Assurance: Genuine parts come with manufacturer-backed warranties for added peace of mind.
Aftermarket alternatives, when sourced from reputable brands like Dayco or Gates, often match these standards at a lower price, but always verify they are OE-equivalent.
How to Choose the Right 2008 Acura MDX Serpentine Belt
1. Prioritize Genuine Fitment
- For the best fit and longevity, look for a belt with these OEM cross-reference numbers: 56992-RV0-A05, 6PK2135, 5060840, K060841.
- OEM or direct replacement belts (Mitsuboshi, Bando) are advisable, especially if your MDX is still under factory warranty or you want maximum reliability.
2. Check Key Specifications
- Rib count: 6 ribs (K-section) is standard for the 2008 Acura MDX.
- Effective length: Approximately 84.0 inches (2133.6mm).
- Material: EPDM is preferred for its durability and resistance to temperature extremes.
3. Evaluate Aftermarket Brands
- Brands like Dayco, Gates, and Bando are recognized for their OE-equivalent quality.
- Look for specifics such as “direct fit,” “OE-equivalent,” and resistance to heat, oil, and wear.
4. Warranty and Support
- Consider the length and terms of the warranty. Genuine belts usually have longer, factory-backed coverage.
- Pay attention to customer support and return policies.
5. Budget and Value
- While genuine belts average $50–$55, reputable aftermarket options can range from $20 to $50.
- Beware of overly cheap, unbranded belts—they may fit poorly or wear quickly.
Practical Tips, Advice, and Best Practices
Inspect Regularly
- Check your serpentine belt every 15,000 miles or at every oil change.
- Look for cracks, fraying, missing chunks, or glazing (a shiny appearance).
Replace Proactively
- Replace the belt every 60,000–100,000 miles, or as your owner’s manual suggests.
- Change the belt sooner if you notice noises (squealing, chirping), loss of accessory function, or visible wear.
Replace Related Components Together
- When replacing the serpentine belt, inspect or replace the belt tensioner and idler pulleys. Many issues manifest due to worn support components, not just the belt.
Use Proper Tools and Procedures
- Always route the new belt according to the engine diagram (usually on a sticker in the engine bay).
- Use a belt tensioner tool for safe removal and installation.
- Ensure the belt ribs sit perfectly in all pulley grooves.
Verify Part Numbers
- For guaranteed fitment, match your VIN or use vehicle lookup tools when shopping online.
Store a Spare (Optional)
- If planning a long trip or if you live far from service centers, carry an extra belt.

FAQ
-
How do I know if my 2008 Acura MDX needs a new serpentine belt?
Common signs include persistent squealing or chirping noises, visible cracks or fraying on the belt, loss of power steering, failure of the air conditioning, or the engine overheating. If your belt looks glazed, stretched, or physically damaged during inspection, it’s time for replacement. -
How often should the serpentine belt be replaced on my 2008 Acura MDX?
Most experts and Acura recommend replacing the serpentine belt every 60,000–100,000 miles, but it’s wise to inspect it regularly for signs of wear, especially if driving in harsh weather or stop-and-go conditions. -
Can I use an aftermarket serpentine belt instead of a genuine one?
Yes, as long as the aftermarket belt comes from a reputable manufacturer (such as Gates, Dayco, or Bando) and matches OEM specifications for length, rib count, and material. “OE Equivalent” or “Direct Fit” products are optimal. -
What part numbers fit the 2008 Acura MDX serpentine belt?
The key OEM part number is 56992-RV0-A05. Equivalent numbers include 6PK2135, 5060840, K060841, and 840K6. Double-check with your VIN or vehicle compatibility tools before purchase. -
Should I replace the tensioner and pulleys when changing the serpentine belt?
It’s highly advisable. Worn tensioners or pulleys can cause even a new belt to fail prematurely. Many manufacturers recommend replacing these components at the same time as preventive maintenance. -
What type of material is best for a serpentine belt?
EPDM (Ethylene Propylene Diene Monomer) rubber is considered the industry standard, providing durability, flexibility, and resistance to extremes of temperature, oil, and moisture. -
Are all 2008 Acura MDX serpentine belts the same length and rib count?
Yes, the standard requirement is a 6-rib, 84.0″ (approx.) belt for the 3.7L engine. However, always check your exact engine and options since regional or accessory differences may occasionally apply. -
Will installing a new belt improve engine performance?
While a new belt won’t boost horsepower, it ensures all driven accessories operate at their designed efficiency—meaning better electrical charging, steering feel, and cooling system performance. -
Can I replace the serpentine belt myself?
If you have basic mechanical skills and the right tools (belt tensioner tool, socket set), it’s a straightforward job for many DIYers. Always follow the routing diagram and safety procedures during replacement. -
What’s the risk of delaying serpentine belt replacement?
Putting off replacement increases the risk of sudden belt failure, which can lead to total loss of driven accessories. This can cause you to lose power steering suddenly, overheat the engine, or be stranded by battery drain. Proactive maintenance is much safer and less costly.
