To vent the cooling system after bypassing the heater core, start by ensuring the engine is cool and the radiator cap is removed. Fill the radiator with coolant until it reaches the proper level, then run the engine with the heater set to the maximum setting to allow air to escape. Keep an eye on the coolant level, adding more as necessary until no more air bubbles are visible, and finally, replace the radiator cap securely. Always check for leaks afterward and ensure the system is operating at the correct temperature.
