Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Remove Engine Covers

Remove the plastic engine cover by unscrewing the bolts securing it in place.
Carefully lift off the cover and set it aside.

3. Drain Engine Oil

Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the oil to fully drain.
Replace the drain plug once the oil has drained completely.

4. Remove Timing Chain Components

Remove the front engine cover by unscrewing all the bolts.
Carefully detach any accessories (like the alternator or power steering pump) that may obstruct access.
Take off the timing chain tensioner by removing the bolts securing it.
Remove the timing chain guides if necessary.

5. Replace Timing Chain

Align the crankshaft and camshaft timing marks according to the service manual specifications.
Install the new timing chain, ensuring it is properly tensioned.
Reinstall the timing chain tensioner and guides, ensuring they are secure.

6. Reassemble Engine

Reattach the front engine cover and tighten the bolts to the manufacturer’s specifications.
Reattach any accessories removed during disassembly.
Refill the engine with new oil through the oil fill cap.

7. Final Checks

Reconnect the negative terminal of the battery.
Start the engine and listen for any abnormal noises.
Check for leaks around the timing chain area.
