Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repair.

2. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, drain pan, funnel, engine oil (recommended grade).
Sub-steps:
1. Remove the oil drain plug using a socket wrench and drain the old oil into a pan.
2. Replace the oil filter using an oil filter wrench; apply a bit of new oil to the rubber gasket of the new filter before installation.
3. Reinstall the drain plug with the proper torque specification (consult the owner’s manual for torque values).
4. Fill the engine with the recommended grade of new engine oil through the oil filler cap.

3. Inspect and Replace Engine Components

Tools Required: Socket set, torque wrench, feeler gauge, multimeter (if necessary).
Sub-steps:
1. Remove any engine covers or components obstructing access to the engine.
2. Inspect the timing chain/belt for tension and wear. Replace if necessary, following manufacturer guidelines for tension specifications.
3. Check the spark plugs for wear; replace if they show signs of fouling or damage.
4. Inspect and clean the fuel injectors using a fuel injector cleaner or replace them if they are faulty.

4. Reassemble and Test

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Reinstall any covers or components removed for inspection.
2. Reconnect the battery.
3. Start the engine and allow it to reach normal operating temperature while monitoring for knocking sounds.
