What does the cooling system of a car engine rely on to cool it?

The question is complex, but the answer is very simple. The engine is divided into oil circuit, electric circuit and cooling system. The main function of the cooling system is to dissipate heat from the engine. However, lubricating oil also has the function of dissipating heat. There is a water tank, circulation, water tank, and cooling fan in the engine. and spare kettle. The circulation route is from the water tank to the engine and back again. The water pump is an individual unit with a fan blade. If the water pump is broken and needs to be replaced, just remove the broken one and replace it with a new one. However, you need to adjust the size of the generator to loosen and tighten the belt. The performance of the thermostat can be scalded with boiling water when it is removed. If it can pop open, it is normal, otherwise it is broken. When replacing water or coolant, open the drain valve under the water tank. After all the coolant is drained, install the drain valve and introduce new coolant. After filling, start the car to circulate the coolant, add enough coolant, cover the water tank cap, and fill up the spare water bottle. The reasons for engine high temperature are 1. Lack of coolant. 2. Poor circulation. 3. The cooling fan does not work. 4. There is too much scale in the water tank. 5. The speed is too slow.
