In this video I cover the proper procedure for refilling and purging air from the cooling system after a cooling system component replacement or a coolant change. Forgetting to bleed the system typically results in the engine running hotter than usual (as evidenced by the dash temperature gauge) or even overheating following a repair. Overheating even once can cause serious engine damage. The bleeding process is pretty straightforward and I’ll take you through the process step by step.
