Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool to avoid burns.
Disconnect the battery if electrical components will be handled.

2. Inspect and Replace Leaking Components

Sub-steps:
1. Identify the source of the coolant leak (hoses, radiator, or engine block).
2. If a hose is leaking, use a socket set to loosen the clamps and remove the damaged hose.
3. Replace with a new hose, ensuring a proper fit and secure with the clamps.
4. If the radiator is leaking, remove it by disconnecting the hoses and mounting brackets.
5. Install the new radiator, reconnect hoses, and secure all connections.
6. If the leak is from the engine block, further disassembly may be required; consult the repair manual for specific instructions based on the component.

3. Refill Coolant

Sub-steps:
1. Locate the coolant reservoir and remove the cap.
2. Use the appropriate coolant type as specified in the owner's manual.
3. Pour coolant into the reservoir until it reaches the recommended level.
4. Replace the cap securely.

4. Test Cooling System

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Check for leaks around the repaired areas.
3. Monitor the temperature gauge for any irregularities.
