Replacing the timing chain is crucial for maintaining engine performance and preventing serious damage. This guide will help you through the process, ensuring you do it correctly and efficiently.

Step 1: Prepare for Timing Chain Replacement

• Gather the necessary tools and parts, including:
  • New timing chain
  • Timing chain tensioner
  • Timing chain guides
  • 10 mm socket
  • 12 mm socket
  • Cleaning supplies
• Ensure the engine is cool and the vehicle is secure on a flat surface.

Step 2: Set Engine to Top Dead Center

• Rotate the crankshaft until piston number one is at the top (TDC).
• Align the timing marks on the camshaft:
  • There should be two lines that meet in the center.
• Confirm proper alignment before proceeding.

Step 3: Remove Old Timing Chain Components

• Remove the timing chain tensioner using a 10 mm socket.
• Be cautious, as the camshaft may move when the tensioner is removed.
• Remove the timing chain guides and the timing chain using a 12 mm socket.

Step 4: Compare New and Old Timing Chains

• Place the old timing chain next to the new one and check:
  • The number of links (should match; for this model, it’s 71 links).
  • Markings on both chains to ensure alignment.
• If the new chain shows any significant slack compared to the old one, it may cause issues.

Step 5: Clean Engine Surface

• Thoroughly clean the engine surface where the timing chain cover will be reattached.
• Remove any old silicone and dirt to ensure a proper seal.

Step 6: Install New Timing Chain

• Position the new chain on the camshaft and crankshaft:
  • Use a marker to highlight the timing marks for better visibility.
• Ensure the links are placed correctly on the cam and crankshaft.

Step 7: Reinstall Timing Chain Tensioner

• Install the timing chain tensioner assembly.
• Before releasing the tension, double-check that all marks are aligned correctly.

Step 8: Rotate the Engine

• Manually rotate the engine two full revolutions.
• Ensure that the engine rotates freely without any obstructions or valve interference.
• Confirm that the camshaft and crankshaft are still aligned with the timing marks.

Conclusion

Replacing the timing chain on a 2015 Hyundai Elantra 1.8 requires careful attention to detail to ensure proper alignment and function. By following these steps, you can complete the replacement successfully. After installation, consider performing regular maintenance checks to monitor the engine's performance. If you encounter issues or are uncertain at any step, consulting a professional mechanic is advisable.
