Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical issues during repairs.

2. Check and Change Engine Oil

Sub-step 1: Remove the engine oil dipstick and wipe it clean, then reinsert it to check the oil level.
Sub-step 2: If the oil level is low, add the appropriate type and amount of oil (typically 0W-20 for most RAV4 models).
Sub-step 3: If the oil is dirty or contaminated, proceed to drain the old oil.

3. Drain Old Oil

Sub-step 1: Place a drain pan under the oil pan.
Sub-step 2: Remove the oil drain plug using a socket set (torque specification: 30 ft-lbs).
Sub-step 3: Allow the oil to fully drain, then reinstall the drain plug.

4. Replace Oil Filter

Sub-step 1: Locate the oil filter and remove it using an oil filter wrench.
Sub-step 2: Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Sub-step 3: Install the new oil filter, tightening it by hand until snug.

5. Refill Engine Oil

Sub-step 1: Pour the new engine oil into the oil filler cap.
Sub-step 2: Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.
Sub-step 3: Turn off the engine, wait a few minutes, and then check the oil level with the dipstick again; add oil as necessary.
