Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Change Engine Oil and Filter

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Drain the old engine oil by removing the oil drain plug and allowing it to fully drain into a pan.
3. Remove the old oil filter using an oil filter wrench. Apply a small amount of new oil to the rubber gasket of the new filter.
4. Install the new oil filter by hand-tightening it and then an additional ¾ turn.
5. Reinstall the oil drain plug and tighten to the manufacturer's torque specification (usually around 30 ft-lbs).
6. Fill the engine with new oil according to the manufacturer’s specifications (typically 5W-20 or 0W-20).

3. Inspect and Replace Timing Components (if necessary)

Sub-steps:
1. Remove any necessary covers to access the timing chain/belt.
2. Check the tensioner and guides for wear and replace them if necessary.
3. If the timing belt/chain is worn, replace it according to manufacturer specifications, ensuring proper alignment is maintained.

4. Inspect Exhaust System

Sub-steps:
1. Visually inspect the exhaust manifold and pipes for any signs of cracks or leaks.
2. Tighten any loose bolts or connections; replace any damaged components as needed.
