To do this, you let the engine cool off and then pressurize the system with a special tool. If you are unable to locate a leak with your eye, the best way is to use a tool that pressurized the coolant system. When the engine is hot, the coolant will evaporate and it could seal the leakage making it very difficult to locate. Another reason you should check for leaks when the engine is cold is because the coolant won’t evaporate. A flashlight can help guide you to any signs of coolant leaks. After you wait for the engine to cool off, check all around and underneath the engine. You always want to make sure the engine is cold because you look around the engine and other parts.

This is generally a clear plastic tank that's off to one side of the radiator. The third component of your cooling system is the coolant overflow tank. Those are the second components of your cooling system. The two tubes that carry the water back and forth from the engine are called the upper radiator hose and the lower radiator hose. Then the water flows back into the engine to reabsorb heat. The water flows from the hot engine through the radiator, with air rushing over the surface from the fan and from the outside air, getting cooled.
This component is basically just a large aluminum heat sink, like the ones you might see on top of the processor inside your computer. There are three main components to the cooling system of your car. I had to replace not only my radiator but get an immediate oil change, as well.
