Solution

1. Preparation

Tools Required: OBD-II scanner, torque wrench, socket set, compression tester.
Ensure the engine is cool before starting the repair.

2. Replace Head Gasket (if required)

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the intake manifold and any components obstructing access to the cylinder head.
3. Drain the engine coolant and remove the cylinder head bolts in the proper sequence (refer to service manual for the correct torque sequence).
4. Carefully lift the cylinder head off the engine block.
5. Clean the surface of the cylinder head and engine block to remove old gasket material.
6. Install the new head gasket, ensuring it is positioned correctly.
7. Reinstall the cylinder head, tightening the bolts to the manufacturer's specified torque settings in the correct sequence.
8. Reassemble all removed components in reverse order.

3. Check and Replace Other Components (if necessary)

Inspect and replace any damaged hoses, the thermostat, or the water pump that may have contributed to the coolant leak.

4. Refill Fluids

Refill the engine with coolant and oil as necessary and reconnect the battery.
