Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the negative battery terminal to prevent electrical issues.

2. Locate and Repair Leaks

Sub-steps:
- Use a pressure tester to identify leaks in the cooling system.
- If leaks are found in hoses, replace with new hoses. Use a hose clamp to secure.
- If the radiator is leaking, remove it by unscrewing the mounting bolts and disconnecting the hoses.
- Install the new radiator and reconnect hoses, ensuring all connections are secure.

3. Inspect and Replace Head Gasket (if necessary)

Sub-steps:
- Remove the intake manifold and cylinder head bolts (follow proper torque sequence).
- Lift the cylinder head and inspect for warping or damage.
- Clean the mating surfaces thoroughly before installing the new head gasket.
- Reinstall the cylinder head, ensuring all bolts are torqued to manufacturer specifications.

4. Flush the Cooling System

Sub-steps:
- Connect a coolant flush kit to the radiator.
- Flush the system with a proper coolant flush solution and water until clear.
- Fill the system with the recommended coolant type and mix ratio.

5. Test Cooling System

Sub-steps:
- Reconnect the negative battery terminal.
- Start the engine and allow it to reach operating temperature.
- Monitor the coolant level and check for leaks again.
