Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent any electrical issues.
Allow the engine to cool down before starting work.

2. Remove Engine Cover

Use a socket set to remove the bolts securing the engine cover.
Carefully lift the cover off and set it aside.

3. Access the Camshaft

Remove the timing belt/chain covers by loosening the bolts (refer to the repair manual for specific torque values).
If necessary, rotate the crankshaft to align timing marks for easier access.

4. Inspect and Replace Camshaft

Inspect the camshaft for wear, scoring, or damage. If defective, remove the camshaft by unbolting it from the cylinder head.
Clean the mounting surfaces on the engine and apply assembly lube to the new camshaft.
Install the new camshaft, ensuring it is properly aligned, and secure it with the specified torque.

5. Reassemble Components

Reinstall the timing belt/chain and covers, ensuring proper tension.
Reattach the engine cover and secure it with the bolts.
Reconnect the battery.

6. Final Checks

Start the engine and listen for abnormal noises.
Check for leaks around the camshaft area.
