4. Refill and Bleed the Cooling System

Sub-steps:
- 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.
- Use the bleeder valve, if available, to remove air pockets from the system.

5. Final Check

Check all connections and the coolant level after the engine has cooled down.
Clean any spilled coolant to prevent attracting animals.
