A vital component of an engine's cooling system, the Radiator is responsible for cooling the active substances (antifreeze, water and oil) in order to ensure the normal temperature of the engine and other units, ensuring a stable vehicle operation.
This device is used in the exchange of heat between the air and these substances, present in a closed system. The shape of the radiator has a direct relationship with its effectiveness, and the heat exchange is faster the greater the area of contact of the equipment with the air
The radiator is used so that together with the water pumping system and the airflow, which is generated by a propeller, is able to dissipate the heat generated by the engine to the environment. As radiators are responsible for the extraction of heat, they are placed in front of the car engine.
Radiators made of plastic and aluminum last between 8 to 10 years. However its necessary to make a revision and cleanup to maintain na extended service life. It’s importante to have a regular verification of the coolant temperature indicator on the instrument panel in order to identify early signs of radiator failure and prevent a breakdown of the cooling system.
Fin: Blade attached to the cooling tubes to increase the area of heat exchange. It can be flat or shrink (zig-zag).
Tubes: Place where the cooling fluid and / or water circulates. It can be oval, round or flat.
Inbox: Component that distributes the cooling fluid / water.
Outbox: Component that collects the cooling fluid.
Although radiators have a robust appearance, they are a sensitive part that requires care from its manufacture, packaging, transportation, installation and use.
Problems and Common Flaws in the Radiator:
Core obstruction – Traces of core obstruction are leakage of coolant and increase in engine temperature.
External dirt on radiator – Signs of dirt on the radiator are overheating of the engine and excessive consumption of coolant.
Lack of pressure – It manifests itself through the appearance of vaporous smoke under the hood and odor of antifreeze, leakage in the radiator of the motor car and the heating of coolant during rapid driving.
