1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery (negative terminal) for safety.

2. Clean the Area

Use a degreaser to clean the area around the suspected leak.
Rinse and dry the area thoroughly to ensure accurate detection of the leak source.

Tools Required: Socket set, screwdrivers
Remove any components obstructing access to the leaking area (e.g., engine covers, intake components).
Label and store removed parts for reinstallation.

4. Replace Seals or Gaskets

If the leak is from the oil filter, remove the old filter and install a new one, ensuring the rubber O-ring is lubricated and properly seated.
For leaking gaskets (valve cover, oil pan), remove the old gasket and clean the mating surfaces.
Install the new gasket, applying the recommended torque settings to the bolts.

5. Tighten Oil Pan and Drain Plug

Check and tighten the oil pan bolts and drain plug to the manufacturer's specification.
Tools Required: Torque wrench
Ensure the oil pan is not damaged; replace if necessary.

6. Reassemble Components

Reinstall any components removed during access to the leak area.
Reconnect the battery.

7. Refilling Oil

Check oil level and refill if necessary, using the recommended oil type for the RAV4.
