RADIATOR ENGINE COOLING FOR VAUXHALL ASTRA/Mk/IV/VAN ZAFIRA ASTRAVAN OPEL VALEO 734388

The VALEO brand Radiator, engine cooling is a key critical element in the internal combustion engine cooling system. Its task is to transfer excess heat generated during fuel combustion to atmospheric air. Even the earliest cars with internal combustion engines had devices resembling a modern radiator, because in the absence of a special element that provides cooling of power units, the work of the latter, as it was found, was simply impossible. A car radiator maintains the temperature of the operating engine within certain strictly specified limits, preventing its overheating and the inevitable jamming in this case.

The construction of the radiator

The core of the radiator consists of horizontally positioned metal plates connected to hollow tubes extending vertically downward from the upper reservoir to the lower reservoir. Thus, when moving through the core, the liquid breaks up into several streams, and an increase in the area of ​​its contact with the atmospheric air occurs, leading to an increase in the cooling intensity.
