Why do you have to check the engine coolant when it s cold?

When the weather is cold, if the engine coolant is not up to standard, the engine coolant may solidify, so the engine's cooling system will have problems and affect the use of the vehicle.

Car prompts to turn off the engine for inspectionCoolantIt is the lack of coolant that causes the high temperature of the engine, and the poor iron of the coolant pump, the failure of the coolant pump, and the dirty radiator will cause this situation

In this case, it is necessary to check whether the coolant level is normal, whether the radiator fan is running normally, whether the radiator is seriously dirty and blocked, and whether the coolant pump is corroded or falsely connected.

Coolant, also known as antifreeze.

Antifreeze, water tank treasure, etc. The main function is to protect the normal and good operation of the engine, and circulate in the engine water tank.

It has the effect of anti-freezing, anti-boiling, anti-rust, anti-corrosion, etc., and the color of most antifreeze is red or green to observe whether it leaks, or to distinguish it from other liquids of the engine to avoid confusion.

Car enginesThe coolant temperature is not as low as possible.

The hazards of low engine coolant are as follows:

1. The combustible mixture entering the cylinder is too low in temperature, which makes it difficult to ignite or burn slowly, resulting in a decrease in engine power and an increase in fuel consumption.

2. The viscosity of the engine oil increases, resulting in poor lubrication, aggravating the wear of parts, and increasing power consumption.

Coolant Introduction:Coolant, the full name should be called antifreeze coolant.

Meaning the coolant with antifreeze function, antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine block when the coolant is parked in the cold season, but we have to correct a misunderstanding, antifreeze is not only used in winter, it should be used all year round, the normal maintenance project of the car, every year of driving, the engine antifreeze needs to be replaced.

Car coolant has to go into the engine. The main function of automobile coolant is to protect the normal and good operation of the engine, circulate in the engine water tank, and play the effect of anti-freezing, anti-boiling, anti-rust and anti-corrosion.

Car coolant can prevent the coolant from freezing and cracking the radiator and freezing the engine block when the coolant is parked in the cold season, but we have to correct a misunderstanding, antifreeze is not only used in winter, it should be used all year round, and the normal maintenance program of the car, every year of driving, the engine antifreeze needs to be replaced.

In the event of a problem with the vehicle, the radiator of the engine oil filter is cooled by coolant. In addition, the sealing inside the cylinder head of the car also has water circulation and oil lubrication channels, if there is a problem in this part, it can cause cold blood to enter the engine. So.

If there is antifreeze in the engine fluid, the engine lubrication system needs to be cleaned and maintained in time.

It is impossible for coolant to enter the engine, and if coolant does enter the engine, the engine will be finished.

Hello, this situation could be a damage to the inside of the oil radiator or a damaged engine head gasket causing coolant to get inside the engine. If you can't continue driving, you should repair it immediately to prevent damage to the engine.

If the gasket is damaged, it needs to be replaced.

In addition, this problem should be dealt with as soon as possible, for a long time will make the oil emulsify, the harm to the engine will increase, and the continuous consumption of antifreeze will make the engine operating temperature continue to be in a high range, but also hinder the normal operation of the engine.

It is possible that the cylinder head gasket is ablated, the water channel is connected to the air channel, and the coolant enters the engine; It is also possible that there is a crack in the cylinder liner and the coolant from the outside seeps into the intake cylinder.

If the cooling water enters the cylinder, it is because the cylinder gasket is burned, and the cylinder gasket is replaced.

In this case, it is necessary to check whether the coolant level is normal, whether the radiator fan is running normally, whether the radiator is seriously dirty and blocked, and whether the coolant pump is corroded or falsely connected.

Coolant, also known as antifreeze.

Antifreeze, water tank treasure, etc. The main function is to protect the normal and good operation of the engine, and circulate in the engine water tank.

It has the effect of anti-freezing, anti-boiling, anti-rust, anti-corrosion, etc., and the color of most antifreeze is red or green to observe whether it leaks, or to distinguish it from other liquids in the engine to avoid confusion.

After the antifreeze enters the oil, it will affect the cooling of the engine, reduce the cleaning effect of the oil and other impurities in the engine, lose the lubrication of the parts, etc., and in serious cases, the engine will be scrapped directly.

Coolant is poured from the reservoir, and the front-engine family car needs about 3 4 liters of coolant, while for a car with a mid-engine or rear-mounted engine, because they still need a water tank at the front of the car to dissipate heat from the cooling system, due to the overall layout, these cars need at least twice as much coolant as a car with a front-engine.

It is equivalent to water entering the engine cylinder, which will produce knocking and knocking on the cylinder; Damaged engine...

The principle is: after the water is inlet at the moment of starting, a piston goes up to complete the compression work before ignition, almost at the same time, the intake valve is closed, so that the inside of the cylinder becomes a sealed space, because the water is incompressible, when the piston goes up to a certain position, the resistance will be significantly increased, but the crankshaft pushed by the other piston that is doing work is ironclad to send the piston to the top dead center position, in short, the water will not make concessions, In contrast, the connecting rod becomes much more fragile (slight deformation), and the water will be discharged out of the cylinder with the opening of the exhaust valve when starting, but the damage it causes to the connecting rod has become a fact, and the bent connecting rod invisibly reduces the compression ratio of the cylinder and increases the resistance of the engine, so the vehicle will feel less energetic when driving, and the driver may not know what is happening in the cylinder, from the driver's point of view, he will think that the car is not strong enough, They will deliberately press the accelerator pedal deeper, and use higher revs to get the power they want to achieve.

The slight bending of the connecting rod will make the operation of the piston in the cylinder extremely unstable, and the excessive speed will undoubtedly speed up its deterioration, at the same time, the swing of the piston in the cylinder will also aggravate the bending degree of the connecting rod, the greater the bending amplitude of the connecting rod, the more crazy the piston swing in operation, until finally, the piston ring is damaged, the cylinder wall is damaged, the piston is stuck in the cylinder, and the connecting rod will also be unable to withstand the huge pressure or bend or break, In a more serious case, the broken connecting rod directly pierced the cylinder. The engine then loses power and the vehicle comes to a stop after a short taxi.

The engine can't wait for the lubrication it should have, it will damage the crankshaft, folio pads, bearings, and then it will stick to the cylinder (cylinder barrel piston), so that the timing will be broken, and the valve beat will be ruined, so that your engine will be meaningless, and it will be about 200 to change back to the oil and add three worries. Friend, let's change the oil. Hope it helps.

The engine is loud and shivering, and the cylinder is rushed
