Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil pressure gauge, oil filter wrench, torque wrench, engine oil, oil filter.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery before starting work on electrical systems.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain the old oil:
  - Remove the oil drain plug using a socket wrench and allow the oil to drain completely into a suitable container.
2. Remove the oil filter:
  - Use the oil filter wrench to carefully remove the old oil filter. Ensure the rubber O-ring comes off with the filter.
3. Install the new oil filter:
  - Apply a thin layer of new oil to the rubber O-ring of the new filter. Install the new filter and tighten to manufacturer's specifications.
4. Replace drain plug:
  - Reinstall the drain plug and tighten to the correct torque specification (typically around 30 ft-lbs).
5. Add new oil:
  - Pour the new engine oil through the oil filler cap, using the correct type and viscosity as specified in the owner’s manual (usually 0W-20 for the RAV4).
6. Check oil level:
  - After adding oil, wait a few minutes, then check the oil level with the dipstick and add oil if necessary.

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan:
  - Support the vehicle securely on jack stands and remove the oil pan by loosening the bolts with a socket set.
2. Inspect the oil pump:
  - Locate the oil pump and inspect it for damage or wear. If it appears faulty, remove it by loosening the necessary bolts.
3. Install a new oil pump:
  - Install the new oil pump and torque the bolts to the specified value. Reinstall the oil pan and ensure a proper seal.
4. Reattach oil drain plug:
  - Replace the drain plug and torque it to specification.
