Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.
Gather all necessary tools and parts.

2. Oil Change (if oil level is low or dirty)

Sub-steps:
1. Drain the old oil using an oil catch pan by removing the oil drain plug.
2. Replace the oil filter with a new one.
3. Refill the engine with the correct grade of oil (typically 0W-20 for this model).
4. Run the engine for a few minutes, then check the oil level and top off as needed.

3. Inspect and Replace Lifters (if ticking noise from valvetrain)

Sub-steps:
1. Remove the engine cover and any components obstructing access to the lifters.
2. Use a torque wrench to carefully remove the valve cover bolts and lift the cover.
3. Inspect the lifters for wear or damage; replace any faulty lifters with new ones.
4. Reassemble by reversing the disassembly steps, ensuring all bolts are torqued to manufacturer specifications.

4. Check and Replace Timing Chain/Belt (if applicable)

Sub-steps:
1. Remove any components that obstruct access to the timing chain/belt cover.
2. Inspect the timing chain/belt for wear and proper tension; replace if necessary.
3. Reassemble everything, ensuring to follow any timing marks and torque specifications.
