In the hot summer, many car enthusiasts are busy “cooling down” their car to prevent heatstroke. However, in addition to cleaning the through-welding water tank and replacing the coolant for the car, many friends also “kindly” removed the “thermostat”, but they did not know that doing so actually caused a hidden damage to the engine.
Air Conditioning System Enhancer
Speaking of the thermostat, many riders are not unfamiliar with it. switch. When it is turned on, the coolant circulates greatly under the action of the water pump, and flows through the external radiator, which is what we call the cooling water tank, so as to achieve a stronger cooling effect; when the thermostat is closed, the coolant conducts a small amount of cooling. Circulation does not flow through the external radiator, but only circulates in the internal water channel of the engine for cooling.
At this time, everyone may have doubts. After the thermostat is removed, the coolant will continue to circulate for a long time. Isn’t the enhanced cooling effect good for the engine? This idea is actually wrong. The most important function of the thermostat is to adjust and maintain the working temperature of the engine within an optimal range. It is like installing an “air conditioner” on the engine, maintaining the temperature at 85 degrees Celsius to 90 degrees Celsius, which is the most suitable for the engine to work, so that the engine will work with the strongest power, the least wear and the lowest fuel consumption.
And what are the dangers of removing the thermostat?
From the perspective of the structure of the cooling system, after the thermostat is removed for some engines with bypass water, not only the coolant will not go through a large circulation, but even the cooling effect of a small circulation will be reduced. Hard to guarantee.
??The engine’s cold warm-up time has increased several times than normal, and the mechanical wear and tear caused by it has increased dozens of times.
??After the thermostat is removed, the working temperature of the engine will be low, resulting in a decrease in thermal efficiency and a decrease in power performance.
??Low working temperature will cause poor fuel atomization, increase fuel consumption, and accelerate the generation of carbon deposits.
A working engine absolutely does not need to remove the thermostat, because the cooling system is designed to withstand the normal thermal load of the engine. Many cars with the thermostat removed are actually accompanied by the failure of “high water temperature”. Removing the thermostat can only be an emergency temporary solution. If the thermostat is removed to treat and prevent the high water temperature, it will only bring you more trouble. big loss. In the same sentence, the engine is afraid of “hot” and “cold”, so install an “air conditioner” on it.
