Functions and How it Works Water Circulation Radiator Thermostat In Car

The function of the thermostat on the engine radiator water circulation - circulation system is the engine cooling system with water or coolant medium can be classified into two: the circulation of short and long circulation .

How it Works Thermostat In Car EngineIn general, the working temperature of the engine , where the engine can work optimally ranged between 80-90 ° C when measured at a temperature in the engine oil and are in the range of 85-95 ° C when the engine temperature is measured through the radiator cap hole .Engine temperature should not be too long to be outside of the figure and the thermostat is a valve that can open and close automatically according to changing temperatures at the engine .Engine Thermostat Toyota 1NZ - FEThermostat can open and close as wax sealed cylinder thermostat is in , the volume of wax can be increased when the temperature rises , the thermostat valve will open , and vice versa if the temperature drops the volume of wax will be reduced and the thermostat valve is closed .Thermostat valve also features a jingle or a small channel that serves the cooling water from the water system when done filling the radiator .It could be concluded that the function Thermostat On Machines is to maintain the working temperature of the engine by opening and closing the radiator drains corresponding temperature indicated on the thermostat body .

Short Circulation Cooling System Water Car Radiator

Short circulation occurs when the temperature of the engine is still cold and aims to accelerate the engine working temperature is reached .When the ignition is first turned on the water in the radiator temperature range at room temperature is about 23 C. When the machine is turned on , the water inside the engine block with the help waterpump circulates water through a hose or pump by-pass or baypass channel without passing through the radiator .Why not pass through the radiator ? That is because the radiator to the water hole was closed by the thermostat , while the by-pass hole located opposite to the hole open allowing waterpump radiator drain water out of the engine block to get back into the engine to cool the cylinder block , cylinder head and oil cooler .Therefore, when the thermostat is not open then it would seem the radiator water does not flow when viewed from the hole radiator ( radiator cap position is opened ) .

When the engine reaches operating temperature, the water temperature in the cooling phase circulation system was increased up to 85-90 degrees Celsius. When the water temperature up to a home thermostat, the thermostat is by the manufacturer are set to open at a temperature between 85-90 degrees celsius open.
Thus allowing the water from entering the engine block to the radiator or water from entering the radiator to the engine block depending on the placement of the thermostat if the thermostat is placed before or after the radiator radiator.
Then waterpump pumping water from the radiator to keep the working temperature of the engine. The water coming out of the engine block went into the radiator to be cooled with the help of the wind from the fan or radiator fan, either mechanically or electrically.

Removing Radiator Thermostat In Water Circulation 

 Misunderstanding that occurred in the vehicle user is removing the thermostat because it is considered to be the cause of the engine temperature should rise .Care should be taken as such other engine components , thermostat also has a shelf life , especially in the rubber found on the thermostat .Indication of the thermostat has been unable to work or to be replaced is the maximum engine temperature rise higher than normal temperatures when viewed from the temperature indicator in the speedometer panel of the vehicle .Removing the thermostat from the radiator water circulation system is not a wise move because the thermostat mengilangkan as a regulator of the water circulating in the cooling system , circulating water will not run perfectly .Without the thermostat , the working temperature of the engine longer achieved , the heating phase and the cooling phase does not occur , because the temperature of the engine is still cold , the water had gone into the radiator , when the water temperature not need to be refrigerated .

How to Check the Thermostat Working Conditions or

To check if the thermostat is still functioning and working well according to unscrew temperature, can be done by removing the thermostat and then boil it in a pot of water.

When the water boils, the thermostat should have opened, if no meaning is not to be used again. And also better to use a thermometer to see what temperature the thermostat opening temperature corresponds to the number indicated on the thermostat body.

 Waterpump Signs Damaged CarsFor water pump, if it appears there was a trickle of water from a hole under the axle pulley, it is an early sign that the waterpump is damaged. Other damage to the waterpump sound when the engine is rotating. Waterpump damaged can not be repaired, it must be replaced with a new one.

If the condition of the thermostat and waterpump in good condition but still above normal temperatures, most likely the radiator is already not functioning properly. That the possibility of a blockage in the water line in the radiator.
