Hi there, I’m Selena. Welcome to my site about automotive systems. The cooling system in your car, truck or van helps keep your engine running efficiently. Without a cooling system, your engine’s internal components would quickly overheat and the car wouldn't go anywhere. The coolant in the radiator runs through the engine block through many different passageways to keep the internal temperatures as low as possible. My site will talk about the way different automotive systems work and explore the maintenance required to ensure their efficiency. I will also share information about system repairs you may come across while owning your vehicle.
