Tools and Parts Required:
- New Timing Belt
- Timing Belt Tensioner
- Water Pump (optional, if replacing simultaneously)
- Socket and wrench set
- Flat-head screwdriver
- Torque wrench
- Pliers
- Coolant (if changing the water pump)
Step 1: Preparation:
- Disconnect the negative terminal of the battery to avoid any electrical hazards.
- Remove the engine cover and any components or covers obstructing access to the timing belt area.
Step 2: Locate Timing Belt:
- Identify the timing belt cover, usually located at the front of the engine. Remove the cover to expose the timing belt.
Step 3: Mark Timing Alignment:
- Before removing the old timing belt, mark the current alignment of the camshaft and crankshaft gears using white paint or correction fluid. This will help you install the new belt in the correct position.
Step 4: Remove Tensioner:
- Locate the timing belt tensioner, which maintains the proper tension on the belt. Loosen the tensioner's locking bolt and pivot the tensioner away from the belt to relieve the tension.
Step 5: Remove Timing Belt:
- With the tension released, carefully remove the old timing belt from the camshaft and crankshaft gears. Be cautious not to disturb the marked alignments.
Step 6: (Optional) Replace Water Pump:
- If replacing the water pump simultaneously, remove the old pump and install the new one, ensuring the gaskets are properly seated to avoid leaks.
Step 7: Install New Timing Belt:
- Align the new timing belt with the marks made on the camshaft and crankshaft gears. Make sure the belt is correctly seated on all the gears.
Step 8: Adjust Tensioner:
- Pivot the tensioner back into position and apply the recommended tension as specified in your vehicle's service manual. Tighten the tensioner's locking bolt.
Step 9: Double-Check Alignment:
- Re-verify that the alignment marks match up, indicating the correct timing. Ensure the belt sits snugly on all gears.
Step 10: Reinstall Components:
- Reattach any components removed during the process, including the timing belt cover and any protective covers.
Step 11: Reconnect Battery:
- Reconnect the negative terminal of the battery.
Step 12: Test Run:
- Start the engine and let it idle for a few minutes. Listen for any unusual noises or vibrations that may indicate incorrect timing.
Note:
- The timing belt replacement procedure might vary slightly based on the specific year and model of your Hyundai Excel hatchback. It's always recommended to refer to your vehicle's service manual for the exact instructions and torque specifications.
- If you're not confident performing this task yourself, consider seeking professional assistance from a qualified mechanic.
