impurities appear in the expansion tank of new energy vehicles

1. It is the gasket of the oil radiator that is damaged or aging.The black impurities in the expansion tank are caused by the damage or aging of the gasket of the oil radiator. As a result, the water pipe is connected to the oil channel, the engine oil is mixed with the antifreeze, or the cylinder pad may be broken. Just go to the repair shop to check the cylinder pad and remove the bar head.

2. When the radiator tube is blocked by impurities, oil and scale, the cooling system will be blocked and the coolant temperature will be too high. The easiest way is to apply a layer of soap, wrap it with tape, and then tie it with wire or thin rope to prevent the antifreeze from leaking out. In this way, you can drive to the repair point to replace a new one.

3. Add coolant according to the specifications. Turn on the ignition switch, connect the vehicle diagnostic instrument, select "Start HEV electric water pump" to exhaust the air in the system. Check again whether the coolant level reaches the upper mark "MAX" of the low-temperature expansion tank, and add coolant if necessary.

4. The reasons are: the antifreeze is added too much and the expansion of the water, the antifreeze is mixed into petroleum products, causing the water, overheating and the water. If the antifreeze is added too much, it will expand and turn the water.

Car expansion tank installation location

1. The radiator tank of this car is in the front of the car, the expansion tank is in the engine compartment, and the expansion tank is a white translucent jar. Most cars use water-cooled engines, which rely on the continuous circulation of coolant in the engine to take away heat.

2. Under the head cover of the car. Jac Junling v6 has a water tank. The automobile water tank, also known as the radiator, is the main part of the automobile cooling system. The water tank is an important part of the water-cooled engine. As an important component of the heat dissipation circuit of the water-cooled engine, it can absorb the heat of the cylinder block.

3. First, open the hood. The white transparent container in the upper left is the expansion tank. Check the pipe connection of the expansion tank. If there is no abnormality, find the expansion pot replenishment pipe and remove the old replenishment pipe. Finally, put in a new water replenishment tube, tighten it, and seal it.

What does the expansion space of the car expansion tank mean

The car expansion tank is filled with coolant. Coolant, the full name should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder when parking in the cold season. Antifreeze is not only used in winter, but should be used all year round.

The expansion tank is a container made of steel plate welding, with various sizes and specifications. The expansion tank is usually connected to the following pipes: (1) Expansion tube, which transfers the volume of water in the system increased by heating and expansion to the expansion tank (connected to the return water trunk). ( 2) The overflow pipe is used to drain the excess water in the water tank that exceeds the specified water level.

The expansion tank is an important part of the HVAC system. Its function is to shelter and compensate for the expansion and contraction of water in the system, and it is also used for system water supply.Generally, the expansion tank is located at the highest point of the system, and it is usually connected to the return water trunk pipe near the suction port of the circulating water pump (central air conditioning frozen water circulating water pump).

The automobile expansion box is a coolant storage box that ensures that the radiator is full of coolant, so that the coolant in the radiator has space to be released when it expands under heat, has a compensation capacity when cooling and shrinks, and has a certain amount of excess water to avoid water shortage.

Function: The expansion tank is an important part of the HVAC system. It accommodates the expansion of the system water in the heating system, and also plays the role of constant pressure and replenishing water for the system. The expansion tank can also stabilize the pressure of the system and exclude the air released by water during the heating process.

Does the car have a water tank?

1. The car using a water-cooled engine has a water tank. The car that uses a water-cooled engine has a heat sink and an expansion tank. The heat sink is in the front of the car, and the expansion tank is in the engine compartment. The water-cooled engine relies on the continuous circulation of antifreeze in the engine to dissipate heat.

2. The car has a water tank, and the car water tank is indispensable for the car.The automobile water tank is the main part of the automobile cooling system. The coolant in the automobile water tank can absorb the heat of the cylinder block and prevent the engine from overheating. Simply put, it has the function of cooling the car and dissipating heat.

3. The car water tank is under the hood of the vehicle. The car water tank is located under the hood of the vehicle. When you open the hood, you can see the water tank cover. There is generally a warning word "high temperature danger" on the water tank cover, which is equipped with antifreeze.

Where is the Junling v6 expansion tank

Hello, there is a cover at the door twist above the co-driver's door of the cab. Open it. With Pepsi bottle, you'd better add a little detergent to the water, so that the wiper and glass friction coefficient will be reduced.

The Jianghuai Junling air conditioning filter is located under the hood, in the upper left corner of the engine.Junling is the basic model of Jianghuai light truck, and it is also the backbone of JAC light truck, located in the medium and short-distance intercity logistics market. Jianghuai light truck is the core business of Jianghuai commercial vehicles, and it is also the cornerstone of the development and growth of Jianghuai Automobile.

The air hole of Jianghuai Junling v6 urea box is next to the cover. There is an air hole on the side of the urea pump cover. Unscrew the lid to open the cover.
