Also, check the tensioner and idler pulleys for excessive play, grinding noises, or rust. This is a good time to decide if you need to replace any pulleys.
- Access: Depending on your specific Accord model and engine configuration, you might need to remove some plastic engine covers or move a power steering reservoir out of the way to gain better access to the belt and tensioner.
Tensioner Release and Old Belt Removal
- Locate the Tensioner: Find the automatic belt tensioner. It will have a square hole or a bolt head (often 14mm, 17mm, or 19mm) designed for a wrench or breaker bar.
- Release Tension: Fit your serpentine belt tool or breaker bar with the correct socket onto the tensioner’s bolt/square hole. Gently apply pressure to rotate the tensioner arm. You’ll feel it pivot, relieving tension on the belt. Note the direction you need to push/pull.
- Remove the Belt: While holding the tensioner arm open, carefully slip the belt off one of the easier pulleys (like the alternator or a smooth idler pulley). Once it’s off one pulley, you can release the tensioner and fully remove the old belt from all components.
- Double-Check Routing: Before tossing the old belt, quickly compare its routing to your diagram one last time. This reinforces the correct path for the new belt.
New Belt Installation: Following the Diagram
This is where your 2013 Honda Accord 2.4 belt diagram guide really shines. Take your time and follow it precisely.
- Route the New Belt: Starting with the crankshaft pulley (the largest, lowest one), begin routing the new belt according to your diagram. It’s often easiest to route it around all the stationary pulleys and accessories first, leaving the automatic tensioner or a small idler pulley for last.
- Ensure Correct Fitment: Make sure the ribs of the belt sit perfectly in the grooves of the ribbed pulleys, and the smooth side of the belt contacts the smooth pulleys. Any misalignment can cause premature wear or the belt to jump off.
- Final Stretch – Tensioner: Once the belt is around all other pulleys, use your serpentine belt tool or breaker bar to again rotate the tensioner arm, creating enough slack. Slip the belt over the final pulley (usually the tensioner itself or an idler pulley).
- Release Tensioner: Slowly release the tensioner arm, allowing it to apply pressure to the new belt. The belt should now be taut and correctly seated on all pulleys.
Post-Installation Verification
- Visual Inspection: Carefully inspect the entire belt path. Ensure the belt is perfectly seated in all grooves and that there are no twists or kinks. The tensioner should be holding the belt firmly.
- Reconnect Battery: Reconnect the negative terminal of your car battery.
- Start Engine: Start your Accord and let it run for a few minutes. Listen for any squealing, chirping, or unusual noises. Observe the belt’s movement; it should run smoothly without wobbling or slipping. If you hear noises, shut off the engine and re-inspect the belt routing and tension.
- Test Drive: Take a short, careful test drive, paying attention to steering, AC, and any warning lights.
Following these steps will help you successfully replace your 2013 Honda Accord 2.4 serpentine belt. It’s a rewarding DIY task that saves money and builds confidence!

Signs of a Failing Belt
- Squealing or Chirping Noise: This is the most common symptom. It often indicates a loose, worn, or misaligned belt, or a failing pulley bearing. The noise might be worse on cold starts or when turning the steering wheel.
- Visible Cracks, Fraying, or Glazing: A visual inspection can reveal significant wear. Cracks on the ribbed side, fraying edges, or a shiny, glazed appearance are clear indicators it’s time for replacement.
- Loss of Power Steering: If the power steering pump isn’t getting adequate power from the belt, steering will become difficult, especially at low speeds.
- Battery Warning Light: A failing belt can prevent the alternator from charging the battery, leading to a battery warning light on your dash.
- Overheating: If the water pump is belt-driven (less common on this engine, but possible if accessory-driven) and the belt fails, your engine could overheat quickly.
- AC Not Working: The AC compressor won’t engage if the belt isn’t driving it.
Identifying Related Issues
Sometimes, the belt itself isn’t the sole culprit. While you’re working with the 2013 Honda Accord 2.4 belt diagram, it’s smart to check other components:
- Tensioner Failure: A worn-out automatic tensioner might not provide enough tension, leading to belt slippage and noise even with a new belt. You can often check for excessive play or a weak spring.
- Idler Pulley Bearing Failure: These pulleys should spin freely and quietly. If you hear grinding, squealing, or feel excessive play when spinning them by hand (with the belt off), the bearing is likely bad.
- Accessory Bearing Failure: The bearings within the alternator, power steering pump, or AC compressor can also fail, causing noise and potentially damaging the belt. Check for resistance or play in these pulleys.
