Solution

1. Preparation

Tools Required: Socket set, torque wrench, coolant pressure tester, OBD-II scanner.
Safety Warnings: Allow the engine to cool completely before starting work. Disconnect the battery to avoid electrical shorts.

2. Address Coolant Leak

Sub-steps:
1. If low coolant is detected, refill to the appropriate level and monitor for leaks.
2. If leaks are found, replace the faulty components (hoses, radiator, etc.).

3. Replace Head Gasket (if applicable)

Sub-steps:
1. Remove the intake and exhaust manifolds.
2. Drain the engine oil and coolant.
3. Remove the cylinder head bolts using the appropriate torque sequence.
4. Lift the cylinder head off and clean the mating surfaces.
5. Install a new head gasket and reassemble the engine, following the correct torque specifications for the head bolts.

4. Inspect Turbocharger (if equipped)

Sub-steps:
1. Disconnect the intake and exhaust connections to the turbocharger.
2. Inspect for oil leaks or coolant intrusion.
3. Replace seals or the turbocharger if damaged.
