If abnormal noise is found in the chassis of the car


How often should we check tire pressure? You should check your tire pressures, including the spare, at least monthly or before every long journey. When checking tire pressure, it should be carried out in a cold tire state, that is, it should be checked after parking for at least three hours. If necessary, the tire pressure should be added to the pressure specified on the car notice board.

Because cold tires give the most accurate readings, drive to the nearest inflation point possible to inflate them. Because the tire pressure is higher than the recommended cold tire inflation pressure after driving the heated tire, so it is forbidden to deflate or decompress the hot tire. Also, check tire pressure with a high-quality tire pressure gauge and don't trust your eyes too much.

You cannot tell from the outside whether a tire is inflated to the correct pressure. Coolant level leaks With the engine cool, check the clear coolant tank. If the liquid level is maintained between the "F" and "L" marking lines of the reservoir, it meets the requirements. If the liquid level is at or below the "L" line, add coolant to bring the liquid level to "F" Wire.

If the coolant level drops within a short time after adding coolant, there may be a leak. Visually inspect the radiator, hoses, engine coolant filler cap, radiator and drain cocks, and water pump to see if water is coming out. If no leaks are found, take your car to a designated service station for further testing.

Note that to prevent burns, do not remove the radiator cap when the engine is still hot. If you find that the chassis has abnormal noise, some cars scratch the chassis during self-driving tours, but they are often ignored during maintenance. According to professionals, if you find abnormal noise in the chassis, shaking of the steering wheel, oil stains in the parking position of the vehicle, etc., it means that the chassis has been damaged.

This is because after road obstacles scratch the chassis, some parts of the chassis may be deformed, especially the upper and lower swing arms, left and right direction tie rods, etc. are prone to deformation. In addition, even some slight scratches can cause slight leakage of the oil pan or the oil pan of the gearbox, and these are problems that the owner cannot detect in time by self-testing. Therefore, it is best for car owners to do professional chassis anti-rust care or spray paint to make a chassis armor.
