- Replace with a new cap if damaged.

3. Refill and Bleed the Cooling System

Reinstall all components.
Fill the cooling system with the appropriate type of coolant (check owner's manual for specifications).
Start the engine and allow it to reach operating temperature.
Open the bleed valve (if equipped) to release any trapped air.
Monitor the coolant level and add as necessary.
