Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Identify and Repair Oil Leaks

Locate the source of the leak:
- Clean the area around the suspected leak with engine degreaser.
- Start the engine and observe for fresh oil leaks.
Replace damaged components:
- If the oil filter is leaking, remove it using an oil filter wrench, lubricate the rubber gasket of the new filter, and install the new filter to the manufacturer's specifications (typically hand-tight and 3/4 turn).
- For leaking gaskets (like the valve cover gasket or oil pan gasket), remove the affected component, clean the surfaces, apply new gasket material or replace the gasket, and reassemble.

3. Change Engine Oil

Drain old oil:
- Place an oil catch pan under the oil pan, remove the drain plug with a socket set, and allow the oil to completely drain.
Replace oil filter and refill oil:
- Install a new oil filter if not already done.
- Replace the drain plug, ensuring it is tightened to the correct torque (usually around 25 Nm).
- Refill the engine with the appropriate type and amount of oil (consult the owner's manual for specifications).

4. Check for Overheating

Inspect the cooling system:
- Ensure proper coolant levels and check for leaks in the radiator and hoses.
- Test the operation of the thermostat and radiator fans.
Replace any faulty components as necessary.
