Solution

1. Preparation

Gather 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 electrical shorts.

2. Inspect Engine Coolant System

Sub-step 1: Remove the radiator cap and inspect the coolant level; add coolant if necessary.
Sub-step 2: Check for any signs of coolant leaks around hoses and the radiator.
Sub-step 3: If any leaks are found, replace the faulty hoses or components.

3. Examine Oil Condition

Sub-step 1: Remove the oil dipstick and check the oil for a milky appearance.
Sub-step 2: If the oil appears contaminated, perform an oil change, replacing the oil filter and using the manufacturer's recommended oil type.
Sub-step 3: Monitor the oil level after the change to ensure no coolant is entering the oil system.

4. Inspect Exhaust System

Sub-step 1: Visually inspect the exhaust pipes, catalytic converter, and muffler for any signs of rust or damage.
Sub-step 2: If corrosion is found, replace the damaged sections of the exhaust system.
Sub-step 3: Ensure all connections are secure and that there are no exhaust leaks.
