Audi and Porsche OEM Radiator and Cooling Parts

Proper functioning of the internal combustion engine depends on the efficiency of the cooling system. The cooling system absorbs and disperses excess heat that is generated by the internal engine. It therefore prevents the engine from overheating. The cooling components are the radiator, thermostat, cooling fan, hoses etc. The radiator is a heat exchange device that cools the engine. Leakages, engine overheating and low coolant levels can indicate a radiator failure. Always replace worn cooling system parts promptly to maintain optimal engine performance and lower maintenance costs.
