2016 Hyundai Accent: Timing Belt vs Timing Chain—How to Replace the Serpentine Belt
Step-by-step accessory drive belt replacement with tools list, belt routing tips, and safety checks
🔧 Accent - Timing Belt Replacement
Your Accent’s 1.6L engine uses a timing chain, not a timing belt. That means there is no scheduled “timing belt replacement” service on this engine.
Most people asking for a “timing belt” on this Accent actually need the engine accessory drive belt (serpentine belt) replaced—this belt runs the alternator and A/C.
Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours
⚠️ Safety & Precautions
- ⚠️ Work on a cool engine; keep hands away from hot parts.
- ⚠️ Keep fingers/tools clear of the belt path and pulleys.
- ⚠️ Do not start the engine until the belt is fully seated on every pulley.
- ⚠️ Battery disconnect is not required, but remove the key and keep it in your pocket.

- Accessory drive belt (serpentine belt) - Qty: 1
📋 Before You Begin
- Park on level ground, set the parking brake, and turn the engine OFF.
- Open the hood and use a flashlight to locate the belt routing sticker (often on the radiator support/upper core support). If missing, take a photo before removal.
- Identify the belt tensioner (a spring-loaded arm that keeps belt tension automatically).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm you’re replacing the correct “belt”
- Use a flashlight to look at the front/side of the engine for the visible belt.
- If you see one external belt driving accessories, that is the accessory drive belt (this is the common DIY replacement).
- The timing chain is inside the engine and is not visible without major disassembly.
Step 2: Release belt tension
- Place a 14mm socket on the tensioner’s hex boss/bolt head.
- Use a 3/8" drive breaker bar (or serpentine belt tool (specialty)) to rotate the tensioner and relieve tension.
- Hold steady—spring force is strong.
Step 3: Slip the old belt off
- While holding the tensioner rotated with the breaker bar, use your free hand to slide the belt off the easiest-to-reach smooth pulley.
- Slowly release the tensioner back to its resting position (do not let it snap back).
- Remove the belt fully by hand.
Step 4: Inspect pulleys and tensioner
- Spin the pulleys by hand (engine OFF) and listen/feel for roughness or wobble.
- Check the tensioner pulley for noisy/rough bearing feel.
- If anything feels gritty or loose, that part should be replaced before installing a new belt.
Step 5: Install the new belt
- Route the new belt to match the under-hood routing diagram (or your photo).
- Start by wrapping the belt around the lower pulleys first, then work upward.
- Leave one easy-to-reach pulley for last.
Step 6: Apply tension and seat the belt
- Use the 14mm socket and breaker bar to rotate the tensioner again.
- Slip the belt onto the final pulley, then slowly release the tensioner.
- Use a flashlight to confirm the belt ribs are fully seated in every grooved pulley (no ribs hanging off).
Step 7: Final alignment check
- Use a flashlight to check the belt tracks straight and is centered on smooth pulleys.
- Make sure no tools are left in the engine bay.
✅ After Repair
- Start the engine and watch the belt for 15–30 seconds (keep hands clear).
- Listen for squeal/chirp. If present, shut off and re-check routing and seating.
- Turn on A/C and electrical loads (headlights) briefly to confirm normal operation.
