The engine coolant temperature sensor is an essential element for monitoring the engine coolant temperature and informing the driver, thus preventing overheating causing a serious fault in scania r440 6x2 for sale. Its operation is not only measurement, but also control.
Early Detection
Thus, the internal resistance of the sensor decreases as the temperature of the coolant that absorbs heat from the engine increases, and vice versa. Depending on the temperature recorded by this sensor, the mixture of fuel and air entering the engine will be adapted. When starting the vehicle, the coolant is at a low temperature and the sensor indicates that a richer mixture (with a greater amount of fuel) is necessary. As the temperature rises, a different ratio is required in the mix . If it is too high, the mixture should be depleted. With such an important function, a failure of the coolant temperature sensor can be serious, so it is important to detect it early. If the sensor needle marks a high temperature with the engine just started or too low if it has been running for some time, it is possible that voltage is not reaching the sensor. In that case, you have to check with a voltmeter that the voltage is between 3 V in cold and 0.5 V in hot, as explained by auto experts.
Operational Aspect
Other symptoms of a sensor failure are instability in engine behavior , with ups and downs in unstable idling, an unwarranted increase in consumption or problems starting. In case the sensor is damaged, it must be taken to a professional to have it replaced . It is normally found in the cylinder head. Once the cables are disconnected, simply change the damaged one to a new one and reconnect it. Cooling is a very important aspect for engine operation, it is responsible for maintaining the ideal engine operating temperature. Cool the hot areas that our engine has and in winter time it prevents the coolant from freezing. To be precise, a used scania r440 6x2 price seeker need to know, ethylene glycol is the coolant used in household equipment and automobiles, it is an odorless and colorless chemical, its consistency is semi-viscous, colorants are applied to differentiate it from the other compounds, it is toxic so its intake is not recommended, it may cause problems severe, coma and death. It comes composed of: anti-corrosion, antifoam and antifreeze additives and has a different boiling point than water, used for refrigeration in domestic and automobile use.
Coolant Vs Water
Initially all the cars were cooled by water. Water is the refrigerant that has the highest heat capacity to remove heat. But its use has limitations such as its boiling point. By evaporating the water can cause cavitation problems, cavitation is a hydrodynamic effect that occurs when a fluid at high speed passes through a sharp edge in the system, the pressure of the steam can increase in such a way that the molecules implode producing a wake gas and metal release. Cavitation generates metal rings in the system, which will generate clogging in the pipes of the system or the coils in the future, as well as damage to the water pump or thermostat. The coolant has antioxidant properties and boiling points higher than water, this helps the cooling system to work efficiently. It is not advisable to supply water or the mixtures between water and coolant. A used car exporter can check the cooling system to detect what the problem is and fix it. This will not put the car's engine at risk, which would lead to a much more expensive repair.
