🔧 Encore - Serpentine Belt Replacement
The serpentine belt is the single long belt that drives accessories like the alternator and A/C. If it’s cracked, squealing, or slipping, replacing it prevents charging problems and overheating.
Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours
Assumption: Access is through the right-front wheel well, typical on your Encore.
⚠️ Safety & Precautions
- 🛑 Work on level ground and use jack stands, not just a jack.
- 🧤 Keep fingers clear of the belt tensioner (spring-loaded arm) while releasing tension.
- 🔥 Let the engine cool fully; the belt area is close to hot parts.
- 🔑 Key off and keep the key away so nobody starts the engine during the job.
- 🔋 Battery disconnect is not required for this repair (unless you’ll be near exposed wiring).

📋 Before You Begin
- 🧭 Park on level ground, shift to P, and set the parking brake.
- Place wheel chocks behind the rear wheels.
- Open the hood and locate the belt routing diagram (usually a sticker near the radiator support). If it’s missing, take a clear photo of the current routing before removal.
- Turn the steering wheel slightly left to improve access at the right-front wheel well.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Loosen the right-front wheel lug nuts
- Use a 19mm socket and 1/2" breaker bar to loosen the lug nuts about 1/2 turn while the tire is still on the ground.
Step 2: Lift and support the Encore
- Use a floor jack at the right-front jack point to raise the vehicle.
- Set the vehicle onto jack stands and gently test stability before working.
Step 3: Remove the right-front wheel
- Use a 19mm socket and 3/8" ratchet to remove the lug nuts.
- Remove the wheel and place it under the vehicle as an extra safety backup.
Step 4: Remove the right-front fender liner (splash shield) section
- Use a 7mm socket to remove any small screws along the liner edge.
- Use a Torx T15 driver for any Torx screws (some liners use a mix of fasteners).
- Use a trim clip removal tool to pop out plastic push clips without breaking them.
- Pull the liner back just enough to clearly see the belt and tensioner.
- Tip: Put screws/clips in a cup.
Step 5: Locate the belt tensioner and relieve belt tension
- Find the belt tensioner (a spring-loaded pulley arm that keeps the belt tight).
- Install a 15mm socket on the tensioner bolt and use a 1/2" breaker bar to rotate the tensioner to release tension.
- While holding the tensioner rotated, use your other hand to slide the belt off the easiest-to-reach pulley (often the alternator or an idler pulley).
- Slowly release the tensioner back to its rest position (don’t let it snap back).
Step 6: Remove the old belt and compare to the new belt
- Pull the belt out through the wheel well opening.
- Compare the old belt to the new belt (length and rib count should match).
- Use a flashlight to inspect pulleys for wobble, cracks, or rough bearings (spin each pulley by hand).
Step 7: Route the new belt onto the pulleys
- Route the new belt using the under-hood routing diagram.
- Make sure the belt ribs sit perfectly in the grooved pulleys and the belt is centered on smooth pulleys.
- Leave one easy pulley for last (the one you’ll slip on while the tensioner is released).
- Tip: One rib off will shred the belt.
Step 8: Apply tension and seat the belt
- Use a 15mm socket and 1/2" breaker bar to rotate the tensioner again.
- Slip the belt fully onto the last pulley, then slowly release the tensioner.
- Double-check belt alignment on every pulley with a flashlight.
Step 9: Reinstall the fender liner
- Reposition the liner and reinstall screws using a 7mm socket and/or Torx T15 driver.
- Reinstall push clips using the trim clip removal tool (and replace any broken clips).
Step 10: Reinstall the wheel and torque the lug nuts
- Install the wheel and snug the lug nuts using a 19mm socket and 3/8" ratchet.
- Lower the vehicle off the jack stands using the floor jack.
- Torque the lug nuts in a star pattern using a torque wrench: Torque to 140 Nm (103 ft-lbs).
✅ After Repair
- Start the engine and watch the belt for 30-60 seconds. It should run smooth with no hopping.
- Listen for squealing or slapping sounds. If you hear it, shut the engine off and re-check routing and seating.
- Turn A/C on and headlights on briefly to add load; belt should still run smoothly.
- After a short test drive, re-check for any loose liner fasteners and confirm there’s no rubbing noise.
