Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Drain Coolant

Place a drain pan under the radiator.
Open the radiator drain valve and allow the coolant to fully drain.
Dispose of the old coolant according to local regulations.

3. Inspect and Replace Leaking Components

Radiator Inspection:
- Check for cracks or corrosion.
- If damaged, remove the radiator by disconnecting the upper and lower hoses and unbolting it from the support brackets. Replace with a new radiator.
Hose Inspection:
- Inspect all hoses for signs of wear, such as bulges or cracks.
- If any hose is compromised, remove the hose clamps, replace the hose, and secure with new clamps.
Water Pump Check:
- Locate the water pump and check for any leaks around the gasket or pump housing.
- If leaking, remove the drive belt, unbolt the water pump, and replace it with a new one. Ensure to clean the mounting surface before installation.

4. Refill Cooling System

Close the radiator drain valve.
Refill the radiator and coolant reservoir with the appropriate coolant type as per manufacturer specifications.
Start the engine with the radiator cap off to allow air to escape and monitor the coolant level.

5. Final Checks

Reconnect the negative battery terminal.
Monitor for leaks while the engine is running and the system is under pressure.
Check the coolant level after the engine reaches operating temperature.
