Allow the engine to cool.

2. Remove Components

Tools Required: Socket set, torque wrench, ratchet.
Disconnect the air intake duct and remove the intake manifold (if necessary).
Remove any accessories obstructing access to the timing cover (e.g., alternator, power steering pump).
Remove the timing cover bolts and carefully remove the timing cover.

3. Inspect and Replace Timing Chain

Examine the timing chain, tensioner, and guides for wear.
If damaged, remove the old timing chain by carefully unbolting the tensioner and guides.
Align the crankshaft and camshaft to the manufacturer’s specifications.
Install the new timing chain, ensuring proper tension is applied.

4. Reassemble Engine
