Dodge Challenger Radiator Caps

While working, the engine of your Dodge Challenger produces a great amount of heat and has to be cooled down in order not to get overheated. Cooling down the engine is the task of a radiator which contains engine coolant. To keep it within the radiator under the required pressure, there is a radiator cap. Acting as a pressure valve, the radiator cap helps to raise the boiling point of the coolant and thus avoid overheating. If you want to be sure the coolant stays inside the cooling system, never ignore a faulty radiator cap.

Apart from keeping the coolant inside, the radiator cap diverts a small quantity of hot coolant into the overflow reservoir and draws it back when the pressure reaches the proper level, thus helping to prevent extra pressure buildup in the system. If your car overheats or the radiator coolant level is too low right after you have just topped it off, have the radiator cap checked as it might be failing.
