This tutorial will guide you through the step-by-step process of replacing the timing belt, ensuring your vehicle continues to run smoothly.

Step 1: Prepare the Vehicle

  • For better access, consider removing the battery from the engine bay.

  • Disconnect any wiring harnesses that may obstruct your work area.

Step 2: Access the Timing Belt

• Remove the Electric Fan and Shroud:

  • With the drive belt out of the way, take off the crankshaft pulley.

• Remove the Timing Belt Cover:

  • Unscrew and remove the timing belt cover to expose the timing belt assembly.

Step 3: Inspect Timing Belt and Components

• Check for Additional Repairs:

  • Inspect surrounding components such as camshaft seals for leaks and replace any worn parts.

Step 4: Drain Coolant

• Prepare for Coolant Drain:
