Solution

1. Preparation

Gather tools: socket set, screwdriver set, coolant, funnel, shop towels.
Ensure the engine is cool and disconnect the battery.

2. Locate the Leak

Use a flashlight to inspect the cooling system components identified in the diagnostic steps.
Clean any coolant residue to easily spot new leaks during the next step.

3. Repair or Replace Affected Components

Radiator:
- If damaged, remove the radiator by unscrewing bolts and disconnecting hoses. Replace with a new radiator.
Hoses:
- If any hoses are cracked or worn, loosen the hose clamps, remove the damaged hose, and install a new one. Ensure clamps are tightened properly.
Water Pump:
- If leaking, drain coolant, remove the water pump by unscrewing bolts, replace with a new pump, and reassemble with a new gasket.
Gaskets:
- If the head gasket is leaking, this is a more complex repair requiring professional assistance as it involves disassembling the engine.

4. Refill the Cooling System

Using a funnel, refill the cooling system with the appropriate type of coolant. Ensure the mixture ratio is correct.

5. Bleed the Cooling System

Start the engine with the radiator cap off, allow it to reach operating temperature, and add coolant as necessary to remove air bubbles.
