The main component of the cooling system in the engine is called the radiator. It is made from aluminum fins for providing the most heat conductivity with a fan attached to one side for removing surplus heat from the coolant which circulates through the engine. A thermostat is also present which functions as a sensor and turns on and off the water pump which helps in circulating the coolant through he engine. For ensuring the maximum engine efficiency, the thermostat will only activate the water pump when the engine reaches its operating temperature.
Preventing leaks in radiators is a part of good vehicle management. Here are some tips to prevent this from occurring.
It is essential to do a regular check on the coolant level, this will help in ensuring an even temperature distribution throughout the radiator and the entire cooling system. This will also prevent thermal cracking which might occur because of the varying temperature in the system. For checking the coolant level, just open the radiator cap located on the top of the radiator. This should only be done when the radiator is sufficiently cooled down and the engine is switched off. Make sure that the water level is visible otherwise it would have to be filled with coolant.
Only the coolant and distilled water recommended by the car manual should be used. Distilled water should be used because it has no contaminants or diluted minerals which will corrode the radiator. Many coolants require a 50:50 ratio mixture before filling the radiator. The radiator has to be filled until the coolant reaches the inlet. Continue filling the reservoir to its top. Put back the radiator cap and flush off the spilled substances with normal tap water.
It is recommended to flush the radiator, it should be done annually for preventing the built-up of debris and rust between the fins that can be a cause of corrosion on the wall. For flushing the radiator, it must be ensured that it is cool before going ahead to work near the engine. The radiator cap at the top has to be released and drain nut located at the bottom side of the radiator has to be unscrewed. A water hose has to be used to pump water in pipe until the water draining from the radiator outlet is clear. While the water is pumped into the cooling system, the engine has to be turned on to allow the water pump to drain surplus remains which might have stuck in the water pump or in the engine internal course.
These simple steps are not difficult to follow, it will help you save your money in the long run besides saving you from hassles.
