What Are the Disadvantages of Not Installing a Thermostat in a Car？

A thermostat will not be installed in a car's water tank. The thermostat is installed on the engine. Having a thermostat on an engine is certainly beneficial, so not having it is certainly harmful. Thermostats generally include electronic thermostats and ordinary thermostats. Whether it is an electronic thermostat or an ordinary thermostat, the thermostat has the same function, but the electronic thermostat is more sensitive and accurate! So what is the harm to the engine if the thermostat is not installed? Let's talk about it below!

First of all, we need to know that the optimal working temperature of the engine is around 95 degrees, and the function of the engine thermostat is to control the circulation of the engine coolant. When the engine is cold started, the coolant temperature is similar to the air temperature, so in order to make the engine reach the best working temperature as soon as possible, when the engine is cold started, the engine idle speed will reach 1500 ~ 2000 rpm, and then as the water temperature increases, the engine idle speed will slow down Slowly reduce to normal idle speed, typically 750 rpm.

At this time, the thermostat is not turned on, that is, the engine coolant is in a small circulation state, that is to say, the coolant in the engine only circulates inside the engine, and there is no heat dissipation from the water tank and the fan. The small circulation is to make the engine reach the best working temperature as soon as possible. That is about 95 degrees.

But what if the engine water temperature rises after reaching the optimum operating temperature? For example, what if it goes up to 110 degrees? At this time, when the water temperature rises to 98 degrees or higher, the thermostat will slowly open and fully open, so that the coolant in the engine will flow to the water tank and dissipate heat through the high-speed operation of the electronic fan, the engine water temperature may be 88 degrees or around 90 degrees. When the water temperature is lower than 98 degrees, the thermostat starts to close, the large circulation of the coolant is closed, and the small circulation is started to keep the engine at the optimal working temperature. Keeping the engine constant temperature is also a condition.

If the thermostat is removed and the thermostat is not used, the engine coolant has been in a state of large circulation, so the water temperature will gradually increase, and the engine water temperature will not reach the optimal working temperature. The coolant temperature is low, the fuel injection volume is large, and the fuel consumption is relatively high, and then the water temperature gradually rises, and the warm air is not too warm in winter.

Without a thermostat, the working temperature of the engine is always lower than the optimum working temperature, and the working state of the engine is not optimal. Summer is fine. There is no thermostat in winter, the water temperature rises very slowly, the engine never reaches the optimal working temperature, and the engine fuel consumption is high. If it is an electronic thermostat, after removing the electronic thermostat, the meter will turn on the engine fault light, so the thermostat of the electronic thermostat cannot be removed, otherwise, it will light up, unless the plug of the electronic thermostat is deceived Engine computer.

In short, don't dismantle the thermostat at will, it's not good for the engine, it's okay in summer, and in winter you know how many consequences will be ignored if you dismantle it.
