Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Change Oil and Filter

Tools Required: Oil filter wrench, socket set, oil drain pan, funnel.
Sub-steps:
1. Remove the oil drain plug and allow old oil to fully drain into the pan.
2. Replace the oil drain plug and tighten to manufacturer specifications (typically 25-30 ft-lbs).
3. Remove the old oil filter using an oil filter wrench; lubricate the rubber gasket of the new filter with new oil before installation.
4. Install the new oil filter and tighten according to specifications.
5. Refill the engine with the appropriate type and amount of oil (typically 0W-20 for RAV4; check the owner’s manual).

3. Inspect and Replace Worn Components

Tools Required: Torque wrench, sockets, screwdrivers.
Sub-steps:
1. If compression or leak-down tests indicate issues, remove the cylinder head to access piston rings or valve seals.
2. Replace worn piston rings and valve seals as needed.
3. Reassemble the engine components, ensuring all bolts are torqued to specifications.
4. Reconnect the battery terminal.
