🔧 Edge - Serpentine Belt Replacement

The serpentine belt on your Edge drives key accessories like the alternator and A/C. Replacing it is mostly about safely gaining access, relieving the spring-loaded belt tensioner, and routing the new belt correctly.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• 🔸 Work on a fully cool engine; belts and pulleys can burn you.
• 🔸 Keep fingers/clothes clear of pulleys; the tensioner is spring-loaded and can snap back.
• 🔸 Support the vehicle with jack stands; never rely on a floor jack alone.
• 🔸 Do not start the engine until all tools are removed and the belt is fully seated on every pulley.
• 🔸 Battery disconnect is not required, but keep the key far away so it can’t be accidentally started.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Chock the rear wheels using wheel chocks.
• Open the hood and look for the belt routing diagram sticker (often on the radiator support/underhood area). If it’s missing, take a clear photo of the current belt routing before removal.
• Lay the new belt out to match length/ribs.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise the right-front corner and remove the wheel

• Use a 21mm lug nut socket with a 1/2" breaker bar to loosen the lug nuts 1/2 turn while the tire is on the ground.
• Lift the right-front using a floor jack (rated 3-ton minimum) and set it securely on jack stands (rated 3-ton minimum).
• Remove the lug nuts with a 21mm lug nut socket and 1/2" drive ratchet, then remove the wheel.

Step 2: Remove the right-front splash shield/inner fender access

• Use a trim clip removal tool to pop out plastic retainers (a trim clip tool is a forked pry tool that removes push-clips without breaking them).
• Use a 7mm socket and 8mm socket with a 1/2" drive ratchet to remove the small screws/bolts holding the access panel/liner section.
• Pull the liner/access panel back enough to clearly see the belt, tensioner, and pulleys. Use a flashlight and inspection mirror as needed.

Step 3: Locate the belt tensioner and confirm routing

• Identify the belt tensioner (spring-loaded arm with a pulley).
• Compare what you see to the underhood belt routing diagram (or your photo) so you know exactly how it goes back on.
• If you see cracking, fraying, or glazing on the old belt, replacement is due (you’re in the right place).

Step 4: Relieve tension and remove the old belt

• Install a 15mm socket on the tensioner’s hex/bolt head and use a serpentine belt tool (specialty) or 1/2" breaker bar for leverage.
• Rotate the tensioner in the direction that moves the tensioner arm away from the belt to loosen it.
• If you’re unsure which way to rotate: apply light pressure one way; if it feels like it immediately “locks,” go the opposite direction. Do not force it.
• While holding the tensioner released, slide the belt off the easiest-to-reach smooth pulley first using your gloved hand.
• Slowly release the tensioner back to its resting position (don’t let it snap).
• Remove the belt from the remaining pulleys and out through the wheel-well opening.

Step 5: Install the new belt (route first, then tension)

• Route the new belt around the pulleys following the underhood routing diagram (or your photo).
• Make sure the ribbed side of the belt sits in the grooves on ribbed pulleys, and the smooth side rides on smooth pulleys.
• Leave the easiest-to-reach pulley for last.
• Use the 15mm socket with the serpentine belt tool (specialty) to rotate the tensioner and slip the belt onto the last pulley.
• Release the tensioner slowly and confirm the belt is centered on every pulley.
• If one rib is off, fix it now.

Step 6: Reinstall the splash shield/liner and wheel

• Reposition the liner/access panel and reinstall fasteners using a 7mm socket, 8mm socket, and 1/2" drive ratchet.
• Reinstall any push-clips using the trim clip removal tool to align them, then press them in by hand.
• Reinstall the wheel and snug the lug nuts using a 21mm lug nut socket and 1/2" drive ratchet.
• Lower the vehicle and tighten lug nuts in a star pattern using a torque wrench: Torque to 203 Nm (150 ft-lbs).

✅ After Repair

• Start the engine and let it idle while you watch the belt for 30–60 seconds (from a safe distance).
• Listen for squealing, chirping, or slapping noises; shut off immediately if the belt walks off a pulley.
• Recheck that the belt ribs are fully seated in the grooves on every ribbed pulley.
• Take a short drive and recheck for noise afterward.
