Solution

1. Preparation

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

2. Drain Coolant

Place a catch basin under the radiator.
Open the drain valve on the radiator or remove the lower hose to drain the coolant completely.
Properly dispose of the old coolant according to local regulations.

3. Inspect and Replace Damaged Components

Radiator and Hoses:
- Remove any damaged hoses using a hose clamp removal tool.
- Install new hoses, ensuring they're secured with clamps.
Water Pump:
- Remove the water pump by unbolting it from the engine block. Use a torque wrench to ensure proper torque specifications during reinstallation.
- Replace the water pump if leakage is found.
- Clean the mounting surface before installing the new pump and apply a new gasket or sealant as required.

4. Refill Cooling System

Reinstall the radiator cap.
Refill the cooling system with the appropriate type and mixture of coolant.
Start the engine and let it run until it reaches operating temperature while checking for leaks.

5. Final Inspection

Check all replaced components for leaks.
Ensure hoses and clamps are secure.
