The performance of your car is greatly dependent on your cooling system. No matter how gutsy its engine is, it can’t work normally without a cooling system. The engine can even be inutile in an instant if it overheats and all other auto parts under the hood can also be damaged. They could melt as the engine burns the fuel inside the combustion chamber and the pistons in the cylinder could expand extremely that they can no longer move to complete the whole process in the engine.
