Sub-steps:
1. Visually inspect all hoses for cracks or bulges.
2. Use hose clamp pliers to loosen and remove any damaged hoses.
3. Replace with new hoses, ensuring proper fit.
4. Tighten hose clamps securely to prevent leaks.

3. Inspect and Replace Water Pump

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
1. Remove the serpentine belt by releasing tension from the tensioner.
2. Disconnect any electrical connectors from the water pump.
3. Remove bolts securing the water pump using a socket.
4. Carefully pull off the water pump and clean the mating surface on the engine.
5. Install a new gasket and the new water pump, tightening the bolts to the manufacturer's torque specifications.

4. Inspect and Repair Radiator

Tools Required: Radiator flush kit, wrenches.
Sub-steps:
1. Check for leaks around the radiator core.
2. If leaks are found, determine if the radiator can be repaired or needs replacement.
3. For replacement, drain coolant, disconnect hoses and mounting hardware.
4. Install a new radiator and reconnect hoses securely.

5. Conduct Pressure Test

Tools Required: Cooling system pressure tester.
Sub-steps:
1. Attach the pressure tester to the radiator or coolant reservoir.
2. Pump the tester to the recommended pressure and observe for any drop in pressure, indicating a leak.
3. Inspect areas around the engine, hoses, and radiator for signs of leakage.
