Remove any components obstructing access to the engine cover (e.g., air intake ducts).
Unscrew the bolts securing the engine cover and carefully lift it off.

3. Inspect Timing Chain Components

Examine the timing chain, tensioner, and guides for wear or damage.
If any components show excessive wear or are damaged, proceed to replace them.

4. Replace Timing Chain Tensioner (if necessary)

Tools Required: Socket set, torque wrench.
Remove the bolts securing the timing chain tensioner.
Carefully pull the tensioner out and install the new tensioner.
Torque the bolts to the manufacturer’s specifications.

5. Replace Timing Chain (if necessary)

Mark the position of the timing chain on the sprockets to maintain timing alignment.
Remove the timing chain by loosening and removing the sprocket bolts.
