Timing Chain Tensioner:
- Remove the bolts securing the tensioner.
- Disconnect the oil supply line if necessary.
- Take out the tensioner and inspect for wear.
Timing Chain:
- Mark the position of the timing chain on the sprockets for reference.
- Remove the bolts securing the sprockets.
- Carefully slide the chain off the sprockets.

4. Install New Timing Chain

Position the new timing chain onto the sprockets, ensuring that the timing marks align correctly.
Reinstall the sprockets and torque the bolts to the manufacturer’s specifications (consult service manual for exact torque values).
Reinstall the timing chain tensioner and ensure it is seated properly.

5. Reassemble Engine
