🔧 Accord - Serpentine Belt Replacement

The serpentine belt drives key accessories (alternator, A/C, power steering). Replacing it restores proper charging and accessory operation and prevents a roadside breakdown if the belt cracks or snaps.

Difficulty Level: Intermediate | Estimated Time: 0.5-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; keep hands away from hot parts.
• ⚠️ Keep fingers/tools clear of the radiator fans; they can turn on unexpectedly.
• ⚠️ Support your Accord with jack stands; never rely on the floor jack alone.
• ⚠️ If you’ll be working near the alternator wiring, disconnect the negative battery cable.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Open the hood and take a clear photo of the belt routing (or the routing sticker if equipped). This prevents misrouting later.
• If you choose to disconnect power: use a 10mm socket to remove the negative battery terminal and tuck it aside so it can’t spring back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front-right corner

• Use a floor jack to lift at the proper front jacking point.
• Set the car onto jack stands and gently shake the car to confirm it’s stable.

Step 2: Remove the front-right wheel

• Use a 19mm socket and 1/2" breaker bar to loosen and remove the lug nuts.
• Remove the wheel and set it aside.
• Reinstall later: Torque to 108 Nm (80 ft-lbs).

Step 3: Remove the right-side splash shield (fender liner access)

• Use a trim clip removal tool (a forked pry tool that pops plastic clips out) to remove the plastic clips.
• Use a 10mm socket and 3/8" ratchet to remove any 10mm bolts holding the shield.
• Use a flathead screwdriver only if a clip is stubborn (pry gently to avoid breaking it).
• Reinstall later: Torque to 9.8 Nm (7 ft-lbs) for 10mm bolts.

Step 4: Relieve tension from the automatic belt tensioner

• Locate the belt tensioner near the belt path.
• Place a 14mm combination wrench on the tensioner’s hex/bolt used to rotate the tensioner.
• Rotate the tensioner smoothly to loosen the belt (you’ll feel strong spring force). Move slowly; don’t let it snap back.

Step 5: Remove the old belt

• While holding the tensioner rotated with the 14mm combination wrench, slip the belt off an easy-to-reach pulley (often the alternator pulley) by hand.
• Slowly release the tensioner back to its resting position.
• Pull the belt out and compare it to the new belt (length and rib count should match).

Step 6: Route the new belt

• Route the new belt following your under-hood routing sticker or the photo you took earlier.
• Make sure the belt ribs sit fully in the ribbed pulleys and the belt sits centered on smooth pulleys.
• If the belt keeps “walking off,” re-check routing—one pulley is usually missed.

Step 7: Apply tension and seat the belt

• Rotate the tensioner again using the 14mm combination wrench.
• Slip the belt onto the last pulley, then slowly release the tensioner.
• Double-check every pulley: no ribs hanging off the edge, no twists.

Step 8: Reinstall splash shield and wheel

• Reinstall the splash shield using the 10mm socket, 3/8" ratchet, and clips with the trim clip removal tool.
• Reinstall the wheel using the 19mm socket.
• Lower the car with the floor jack and remove the jack stands.
• Final-tighten lug nuts in a star pattern: Torque to 108 Nm (80 ft-lbs).

Step 9: Reconnect battery (if disconnected)

• Use a 10mm socket to reinstall the negative battery terminal clamp snugly.

✅ After Repair

• Start the engine and watch the belt for 20-30 seconds; it should run straight with no wobble.
• Turn A/C on and rotate steering wheel lightly; listen for squeal (misrouting or poor seating is most common).
• After a short test drive, recheck belt alignment through the wheel well opening or from above.
