Solution

1. Preparation

Tools Required: Oil catch pan, socket set, torque wrench, oil filter wrench, funnel, and oil.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if performing any electrical checks.

2. Check and Replace Oil

Step 1: Remove the oil drain plug using a socket wrench and allow the old oil to drain into the catch pan.
Step 2: Replace the drain plug and torque it to the manufacturer's specifications (typically around 20-30 Nm).
Step 3: Remove the old oil filter using an oil filter wrench and ensure the rubber O-ring comes off with it.
Step 4: Lubricate the new oil filter O-ring with fresh oil, install the new filter, and tighten it according to specifications.
Step 5: Add the recommended type and amount of oil through the oil filler cap using a funnel.

3. Inspect and Replace Seals/Gaskets (if necessary)

Step 1: Identify any leaking seals or gaskets (such as the valve cover gasket or oil pan gasket).
Step 2: Remove any components obstructing access to the gasket/seal.
Step 3: Remove the old gasket/seal and clean the mating surfaces thoroughly.
Step 4: Install the new gasket/seal, ensuring proper alignment, and reassemble any removed components.
