Radiator:
- Remove the radiator shroud (if applicable) to gain access.
- Inspect for leaks, and replace the radiator if damaged.
Hoses:
- Check all hoses for cracks or softness.
- Replace any damaged hoses with new ones, ensuring proper fit and tightness.

3. Fill and Bleed the Cooling System

Reconnect all components and hoses securely.
Fill the coolant reservoir with the manufacturer-recommended coolant mixture.
Start the engine and allow it to reach operating temperature.
Open the bleed valve (if equipped) to release any trapped air in the system.
Monitor coolant levels and top off as needed.
