1. Preparation

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

2. Check and Replenish Oil

Tools Required: Socket set, oil filter wrench, oil catch pan
Remove the oil filler cap and check the oil level with the dipstick.
If low, add the recommended type and grade of oil to the engine.
Check for leaks after adding oil.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set
Locate the oil filter; use the oil filter wrench to remove it.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, following the manufacturer's torque specifications.

4. Replace Engine Oil

Tools Required: Oil catch pan, funnel, socket set
Place the oil catch pan under the oil pan and remove the drain plug.
Allow the old oil to fully drain into the pan.
Replace the drain plug and tighten to the specified torque.
Refill the engine with the appropriate amount of new oil through the oil filler cap.

5. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench
If low oil pressure persists, remove the oil pump from the engine.
Inspect the pump for wear or damage; replace if necessary.
Reinstall the new or inspected oil pump, ensuring proper torque specifications are met.
