🔧 Fit - Serpentine Belt Replacement

Replacing the serpentine belt on your Fit requires moving the spring-loaded automatic tensioner, removing the old belt, and routing the new belt correctly around every pulley. Replace the belt if it has cracks, frayed edges, missing ribs, glazing, or persistent squealing.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour

⚠️ Safety & Precautions

• ⚠️ Switch off the engine, remove the key, and let the engine cool completely.
• ⚠️ Keep fingers out of the spaces between the belt and pulleys.
• ⚠️ The automatic tensioner is spring-loaded. Hold the wrench securely and release it slowly.
• ⚠️ Never work beside or beneath your Fit while it is supported only by a floor jack.
• ⚠️ Wear safety glasses because dirt can fall from the wheel well.
• 🔋 Battery disconnection is not required for this repair.

📋 Before You Begin

• 🅿️ Park your Fit on firm, level ground. Apply the parking brake and place the transmission in Park or first gear.
• 🛞 Place wheel chocks behind both rear wheels.
• 📷 Photograph the existing belt routing from above and through the right-front wheel well.
• 🔎 Locate the underhood belt-routing label. Follow that label if it differs from your photograph.
• 📱 Infotainment settings and scan-tool commands are not required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Right-Front Wheel

• Use the 19mm lug-nut socket and 1/2-inch-drive breaker bar to loosen each wheel nut approximately one-quarter turn.
• Leave all wheel nuts installed until your Fit is safely supported.

Step 2: Raise and Support Your Fit

• Use the 2-ton floor jack at the designated front jacking point.
• Position the 2-ton jack stand beneath the reinforced right-front side support point.
• Lower your Fit onto the stand. Gently push the body to confirm it is stable.
• Never trust a hydraulic jack by itself.

Step 3: Remove the Right-Front Wheel

• Use the 19mm lug-nut socket to remove the five wheel nuts.
• Lift off the wheel and place it flat away from your work area.

Step 4: Open the Belt Access Area

• Use the flat-blade trim-clip remover to release the clips along the front section of the right inner-fender liner.
• A trim-clip remover is a forked hand tool that lifts plastic fasteners without damaging them.
• Pull the liner aside only far enough to expose the crankshaft pulley and lower section of the belt.
• Use the LED work light to verify the belt routing before removal.

Step 5: Release the Automatic Tensioner

• Place the 19mm long-handle box-end wrench fully onto the tensioner pulley bolt.
• The automatic tensioner is the spring-loaded arm that maintains belt tension.
• Viewed from the right-front wheel opening, rotate the wrench clockwise to move the tensioner and create belt slack.
• Hold the tensioner in the released position and slide the belt off an accessible smooth pulley by hand.
• Keep your fingers away from pulley edges, then allow the tensioner to return slowly to its resting position.
• Never release the tensioner suddenly.

Step 6: Remove the Old Belt

• Wear mechanic’s gloves and guide the belt off the remaining pulleys.
• Pull the belt out through the right-front wheel opening.
• Lay the old and new belts together. Confirm that their width, rib count, and overall length are nearly identical.
• A worn belt may be slightly longer because it has stretched.

Step 7: Inspect the Belt Drive

• Use the LED work light to inspect every visible pulley groove for stones, rubber buildup, or damage.
• Turn accessible idler pulleys by hand. They should rotate smoothly without grinding, wobbling, or looseness.
• Inspect the tensioner for a crooked pulley, weak movement, or fluid leakage from its damping mechanism.
• Replace a defective pulley or tensioner before installing the new belt.
• Do not apply grease, oil, silicone spray, or belt dressing.

Step 8: Route the New Belt

• Route the new belt exactly as shown on the underhood routing label and your reference photograph.
• Place the ribbed face of the belt into grooved pulleys. Place the smooth back of the belt against smooth pulleys.
• Make sure the belt is fully seated around the lower crankshaft pulley.
• Leave one easily reached smooth pulley until last.
• Use your phone photo as a routing guide.

Step 9: Seat the Belt and Release the Tensioner

• Place the 19mm long-handle box-end wrench onto the tensioner pulley bolt again.
• Rotate the tensioner clockwise and hold it against spring pressure.
• Slide the belt over the final smooth pulley by hand.
• Inspect every grooved pulley with the LED work light. Each belt rib must sit inside a matching pulley groove.
• Slowly release the 19mm long-handle box-end wrench until the tensioner applies full pressure.
• No tensioner-bolt torque is required because that bolt is not removed.

Step 10: Perform the Final Routing Check

• Use the LED work light to follow the belt around its complete path.
• Confirm that the belt is not twisted, pinched, or hanging over any pulley edge.
• Pay particular attention to the crankshaft pulley because its lower edge is difficult to see.

Step 11: Reinstall the Inner-Fender Liner

• Move the liner back into its original position.
• Install reusable clips by hand, then press their center pins flush.
• Use the flat-blade trim-clip remover to align stubborn clip holes without tearing the liner.
• Replace any broken or loose clips.

Step 12: Reinstall the Wheel

• Place the wheel onto the hub and start all five wheel nuts by hand.
• Use the 19mm lug-nut socket to snug the nuts in a star pattern.
• Use the 2-ton floor jack to raise your Fit, remove the jack stand, and lower the tire onto the ground.
• Use the 1/2-inch-drive torque wrench and 19mm lug-nut socket to tighten the wheel nuts in a star pattern: Torque to 108 Nm (80 ft-lbs).

✅ After Repair

• ✅ Check that all tools are clear of the engine compartment before starting the engine.
• 👀 Start the engine and observe the belt from a safe distance. Do not reach into the engine compartment.
• 👂 Switch the air conditioning and headlights on. Listen for chirping, squealing, slapping, or grinding.
• 🛑 Stop the engine immediately if the belt wanders toward a pulley edge or the charging-system warning appears.
• 🔎 Switch off the engine and perform one final belt-alignment check with the LED work light.
• 🛞 Recheck wheel-nut torque after approximately 80-100 km of driving.
