Solution

1. Preparation

• Gather tools and materials. Ensure the vehicle is parked on a flat surface.
• Tools Required: OBD-II scanner, socket set, multimeter, coolant pressure tester, safety glasses, gloves.
• Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool down before inspecting components.

2. Inspect and Replace Coolant

• Step 1: Remove the engine cover (if applicable) using a socket set.
• Step 2: Use a coolant pressure tester to check for leaks in the cooling system.
• Step 3: If leaks are found, replace the affected hoses or components.
• Step 4: Drain the old coolant using a drain pan and replace it with the manufacturer-recommended coolant.
• Step 5: Reinstall the engine cover and check for any visible leaks.

3. Inspect and Clean Battery

• Step 1: Disconnect the battery terminals, starting with the negative terminal.
• Step 2: Inspect the battery for any leaks or corrosion around the terminals.
• Step 3: If corrosion is present, clean the terminals using a mixture of baking soda and water.
• Step 4: Reconnect the battery terminals securely.

4. Check for Fluid Leaks

• Step 1: Visually inspect the area under the engine and transmission for any signs of leaking fluids.
• Step 2: If a leak is present, identify the source and replace any damaged seals or gaskets.
• Step 3: Clean any spilled fluids from the engine bay to eliminate odors.
