Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather all necessary tools and safety equipment.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Engine Oil

Sub-steps:
1. Remove the oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, add the appropriate oil type (5W-20 or as specified in the owner's manual).
4. If the oil is dark or has debris, perform an oil change.
Tools Required: Oil filter wrench, socket set, oil catch pan.

3. Replace Spark Plugs

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coil connectors and remove the coils.
3. Use a spark plug socket to remove the old spark plugs.
4. Install new spark plugs, ensuring the correct gap (usually 0.043 inches for RAV4).
5. Reassemble the ignition coils and engine cover.
Tools Required: Spark plug socket, torque wrench.

4. Inspect and Adjust Valve Clearance

Sub-steps:
1. Remove the valve cover using a socket set.
2. Check the valve clearance using a feeler gauge; adjust if necessary according to the manufacturer's specifications.
3. Replace the valve cover gasket if it shows signs of wear.
4. Reinstall the valve cover and torque to the manufacturer's specifications.
Tools Required: Feeler gauge, torque wrench.

5. Inspect Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt cover.
2. Inspect the timing chain/belt for wear, slack, or damage.
3. If necessary, replace the timing chain/belt following the manufacturer's guidelines.
Tools Required: Socket set, timing tool (if necessary).
