What is the use of the water pipe on the car engine

The water pipe is divided into upper water pipe, lower water pipe, and secondary water tank connected to the water pipe. The car generates heat when driving, so it uses water to lower Warm. There are many small holes in the cylinder block. The function of the water tank is to store spare water. When the water in the cylinder body reaches a certain temperature, the thermoster will automatically open.

The coolant is cooled from the sewer pipe of the water tank into the reaction machine through the pump. It comes out of the engine and enters the water tank through the upper pipe and circulates in turn. We all know that when the hot water goes up, the temperature of the radiator will be high above and the temperature below will be low, which can also reduce the impact on the pump.

[Pacific Automobile Network] The function of the engine water pipe is to form a part of the cooling system, transmit the coolant, and assist the coolant to dissipate the engine. At the same time, the function of the water pipe is to change the water flow rate in various places in the pipe through its own shape, so as to balance the coolant flow in various places, so as to balance The heat of the engine.

The main function is to transfer the coolant and assist the coolant to dissipate heat from the engine. Water pipes are divided into: upper water pipe, sewer pipe (connecting the water tank and the end of the water pump), warm air pipe (for air conditioning), iron water pipe, etc. Each water pipe has its own function, but what can generally be seen is mainly the upper and lower pipes in the cooling system.

The main function of the warm air pipe is to flow the engine coolant into the warm air tank, and the heat source of this air conditioning heating system is available.If the warm air pipe is blocked, the car air conditioning and heating system will not work.

Can the warm air pipe be used as a gasoline pipe? The warm air pipe is water-resistant and oil-resistant. When it touches gasoline, the rubber will decompose and melt. What is the function of the warm air pipe of the car engine? What will happen if it is blocked? The main function of the warm air pipe is to flow the engine coolant into the warm air tank, and the heat source of this air conditioning heating system is available.

Wuling b12 engine five-way water pipe installation method

One end of the upper water pipe is connected to the water tank, and the other end is connected to the outlet of the engine waterway pump. One end of the sewer pipe is connected to the drain chamber of the water tank, and the other end is connected to the inlet of the engine waterway.

Water pipe. According to the official website of Wuling, the Wuling B12 engine thermoster is at the other end of the upper water pipe, next to the distributor, and the external hose is connected to the water tank.

The first step is to turn off the engine first to replace the thermosulator. Step two, after turning off the car engine, find the hood switch on the side of the cab door and pull it to open. The third step is to open the front cover and find the battery of the car in the engine compartment.Step four, then disconnect the negative wire of the car battery to prevent electric shock during installation.

What does the water pipe sign of the car engine fault light mean?

The faucet sign on the dashboard refers to the engine fault light, indicating that the engine is faulty. If the engine fault light turns on while driving, it is likely that the engine has problems due to poor combustion of the engine, such as engine explosion, engine carbonisation, etc.

There is a faucet sign on the dashboard of the car, which is the car engine fault light. The long light indicates that there are problems such as poor engine combustion, engine explosion, poor fuel quality, and unclean interior of the engine cylinder.

Oil pressure alarm light. This appears.The alarm light indicates that the oil pressure is insufficient to meet the oil lubrication of the engine, so it must be checked and repaired when it appears. Generally, in this case, it is necessary to first check whether the oil is missing, whether the oil is on, whether the oil pressure sensor wire has fallen off and iron, and whether it is damaged. It is recommended to repair it as soon as possible.

There is a faucet sign on the dashboard of the car, which is the car engine fault light. The long light indicates that there are problems such as poor engine combustion, engine explosion, poor fuel quality, and unclean interior of the engine cylinder. During our driving process, if the engine fault light turns on, it is likely that the engine is not burning well.

The car faucet sign is the engine fault sign. The yellow light on the faucet sign indicates that the engine is faulty. Because it is a yellow light, the fault is not very serious.If the red light is on, it will be very serious. You need to stop the car for inspection immediately. If you can't find it, you can only call for help.

There are upper water pipes and lower water pipes in the car tank. Which one is the inlet pipe and which one is the outlet pipe?

The upper water pipe of the car water tank is the inlet pipe, and the sewer pipe is the outlet pipe. Above the car water tank is the water tank inlet pipe, and below the car water tank is the water tank outlet pipe. Judging from the direction of the water flow in the pipe, simply put, it is "up in and out".

The car water tank has two upper and lower water pipes. One end of the upper water pipe is connected to the upper water chamber of the water tank, the other end is connected to the outlet of the engine water pump, one end of the sewer pipe is connected to the drain chamber of the water tank, and the other end is connected to the inlet of the engine waterway.As a result, a cooling water cycle is formed in which the engine is in and out, and the water tank is in and out.

Connect the water pipe, the upper water pipe, the water outlet of the cylinder head or the drain pipe of the thermoster cover, the exhaust pipe of the water pump inlet port, the expansion pot water replenishment pipe, and the top of the storage kettle will not appear on the same water tank at the same time.

The two pipes above the water tank, one is the inlet pipe and the other is the outlet pipe. The high part is the inlet pipe, and the low part is the outlet pipe. That is to say, the water pipe that enters the engine is the sewer pipe, and the water pipe that comes out of the engine is the upper water pipe.
