Solution

1. Preparation

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

2. Inspect and Replace Damaged Hoses

Sub-steps:
- Use a socket set to remove any clamps securing the leaking hoses.
- Disconnect the hoses from the radiator and engine.
- Inspect the hoses for cracks or brittleness; replace if necessary.
- Install new hoses, ensuring proper alignment and secure with clamps.

3. Repair or Replace the Radiator

Sub-steps:
- Remove the front grille or bumper as necessary for access.
- Disconnect the upper and lower radiator hoses.
- Remove mounting bolts using a socket set.
- Carefully remove the radiator and inspect for leaks.
- If damaged, replace with a new radiator; if repairable, use appropriate sealant.

4. Address Water Pump Issues

Sub-steps:
- Locate the water pump, usually at the front of the engine.
- Remove any components obstructing access (like the serpentine belt).
- Inspect for leaks around the pump seal.
- If leaking, remove the water pump by unscrewing the mounting bolts.
- Install a new water pump and secure it with the recommended torque specifications.

5. Refill and Bleed Cooling System

Sub-steps:
- Reconnect all hoses and components removed during repairs.
- Fill the coolant reservoir with the appropriate coolant type.
- Run the engine with the radiator cap off to allow air to escape.
- Monitor the coolant level and add as necessary until the system is bled of air.
