Chenglong H7 hight quality Expansion tank 4H7CL38D33X0A-1311010C

Description

The auxiliary water tank of the Chonglong H7 is also known as the expansion water tank. It is a crucial auxiliary component in the vehicle’s cooling and heat dissipation system. Here is the detailed introduction:

Function of the Expansion tank 4H7CL38D33X0A-1311010C:

It is mainly used to balance the pressure in the water tank and ensure the normal operation of the cooling system. When the engine temperature rises, the coolant expands, and some of the antifreeze will flow into the auxiliary water tank through the water tank cover; when the temperature drops, the pressure in the cooling system becomes negative, and the system will draw the antifreeze in the auxiliary water tank into the cooling system through the water tank cover. In addition, there are scales on the auxiliary water tank, which can be used to indicate the liquid level height, allowing car owners to intuitively understand the water tank’s water volume and determine whether to add antifreeze.

Expansion tank 4H7CL38D33X0A-1311010C Location:

It is usually located in the engine compartment, close to the radiator or connected to the main water tank. It is generally a plastic cylinder with small water pipes connected to it.

Expansion tank 4H7CL38D33X0A-1311010C and material:

Common models include 4H7CL38D33X0A-1311010C1, 4H7YC60D33X1C-1311010B7, etc. The material is plastic, which has certain corrosion resistance and impact resistance, and can adapt to the high-temperature environment inside the engine compartment.

How to determine the quality of the Expansion tank 4H7CL38D33X0A-1311010C:

1. Inspect the appearance: Check if there are any obvious deformations, cracks or damages on the surface of the auxiliary water tank. If so, it may affect its normal use. At the same time, check if there are any water stains at the connection points between the auxiliary water tank and the water pipes, as well as around the water tank cover. If there are water stains, it indicates that there might be a leakage problem, and the auxiliary water tank may be damaged.

2. Check the coolant status: Observe the coolant level in the auxiliary water tank. If the coolant level keeps dropping frequently and there are no obvious water leakage marks on the vehicle exterior, it may indicate a leak inside the auxiliary water tank. Additionally, the normal coolant is usually clear. If you notice that the coolant has become cloudy or has bubbles, it could suggest that there is a problem with the auxiliary water tank, causing the coolant to be contaminated or allowing gas to enter.

3. Pay attention to the water temperature gauge: During vehicle operation, keep an eye on the water temperature gauge on the dashboard. If the pointer of the water temperature gauge rises rapidly to the high temperature range, or the water temperature warning light comes on, while the radiator fan is operating normally, it may be that the auxiliary water tank is faulty, which has affected the normal operation of the cooling system, resulting in poor engine cooling.

4. Listen for abnormal sounds: After the vehicle is started, if you hear an abnormal gurgling or flowing sound coming from the engine compartment, it could be that the coolant in the auxiliary water tank is flowing abnormally or there is still air that has not been expelled. This might also be a sign of a malfunction in the auxiliary water tank.
