Solution

1. Preparation

Tools Required: OBD-II scanner, pressure tester, basic hand tools (sockets, wrenches), flashlight, safety glasses, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool down before inspecting components.

2. Address Fluid Leaks

Step 1: Identify the source of any leaks. Clean the area around the suspected leak with a degreaser.
Step 2: Replace any damaged hoses or seals. Ensure all connections are tight to prevent further leaks.
Step 3: Refill any lost fluids to the manufacturer’s specified levels.

3. Inspect and Replace Affected Components

Step 1: Check all belts for signs of wear or damage; replace if frayed or cracked.
Step 2: Test the operation of the cooling fan. If the fan is not functioning, replace the fan motor.
Step 3: If any brakes are overheating, inspect the brake pads and calipers. Replace worn brake pads or sticking calipers.

4. Test Cooling System

Step 1: Attach the pressure tester to the radiator cap opening.
Step 2: Pump the tester to the specified pressure (usually around 15-20 psi).
Step 3: Inspect for any leaks in the radiator, hoses, and connections. Repair or replace any faulty components.
