If the engine is not overheated, can you safely remove the radiator cap?

Removing the radiator cap should always be treated with caution, even if the engine is not overheated. The cooling system is pressurized, and when the cap is removed, it can release hot coolant and steam, potentially causing burns or injuries. This pressure can exist even in a cool engine since the system is designed to maintain a certain level of pressure to raise the boiling point of the coolant and improve the efficiency of the cooling system. Therefore, it is essential to wait until the engine has cooled down significantly before attempting to remove the radiator cap to avoid any risk of injury from escaping steam or hot fluid. This understanding is crucial for vehicle safety and personal protection during maintenance.
