Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the engine is cool and disconnect the battery.
Gather a drain pan for coolant collection.

2. Locate and Repair Leaks

Visual Inspection:
- Inspect all hoses, the radiator, and the water pump for leaks.
Repair/Replace:
- Tighten loose hose clamps.
- Replace any cracked or damaged hoses.
- If the radiator is leaking, replace it.
- If the water pump is faulty, proceed to replace it.

3. Flush the Cooling System

Drain Coolant:
- Open the drain valve on the radiator and let the coolant flow into the drain pan.
Flush:
- Use a flushing agent as per manufacturer specifications or water to thoroughly rinse the system.
Refill:
- Close the drain valve and refill with the appropriate coolant mixture (50/50 water and antifreeze).

4. Replace Components (if necessary)

Water Pump Replacement:
- Remove the serpentine belt.
- Unbolt the water pump from the engine block and remove it.
- Clean the mounting surface and install the new water pump with a new gasket.
- Torque the bolts to manufacturer specifications.
Radiator Replacement:
- Remove the hoses connected to the radiator.
- Unbolt and remove the radiator from the support.
- Install the new radiator and reconnect hoses.

5. Final Checks

Check for Air Bubbles:
- Start the engine and let it idle until it reaches operating temperature, then check for air bubbles in the reservoir.
Top Off Coolant:
- Add coolant if necessary.
