Basic concepts Most motor vehicles equipped with a thermal engine (petrol or diesel) need a cooling system. Friction inside the engine, internal combustion, the sorrounding environment and other vehicle parts, cause engine temperature to rise. For proper engine function, these temperature fluctuations must be controlled.
It´s vital to control engine temperature!!
Engine temperature is controlled with "heat changers" within its environment. The principle is to obtain heat from the engine and pass it onto the environment. To achieve this, most cars use the common cooling system. It´s mainly composed by three components: radiator, coolant and a water pump.
Recommendations The user must control these factors:
- Tempereture sensor: located inside the vehicle, it warns the user when temperature inside the engine reaches unsafety levels. Most sensors are color labelled. This makes it easy to identify high temperatures.
- Coolant check: for correct level and state (free of oxide traces). Also known as antifreeze, it should never be used for more than 24 months. After that, a coolant change is adviced.
- Coolant certificates: most refrigerants must have safety and testing certificates acknowledged by manufacturers. Look for them at the time of purchasing this product. The most common ones are AFNOR 15.601, UNE 26.361.88, INTA 157413, ASTM
D-3306, D-4656, D-4985, D-5345, SAE J-1704, FEDERAL STANDARD O-A-548D and BRISTISH
- Circuit and radiator flushing: a common error when substituting a faulty radiator is to ignore the fact that the system should be flushed. If this the case, most corrosion particles will end up breaking the replacement radiator. This will result in a warranty loss.
