engine oil, the lifeblood of your engine. Also known as motor oil, it reduces friction, cools parts, and prevents wear. Using the wrong type or waiting too long to change it can lead to costly damage. And no, you don’t need to drive right after adding oil—waiting a few minutes lets it settle properly. Then there’s the car radiator, the system that keeps your engine from overheating. Also known as cooling system, it circulates coolant to manage heat. A leak, a clog, or a failed fan can turn a simple fix into a breakdown. And let’s not forget the fuel pump, the part that pushes gas from your tank to the engine.
