Does the deformation of aluminum sheet of automobile radiator affect it?
Deformation of aluminum plate of automobile radiator will affect heat dissipation. If the area is small, it will not have an impact; However, if the area is large, the air conductivity will be reduced, resulting in poor heat dissipation of the vehicle. At this time, it can be solved by smoothing with paper clips. First of all, please make sure that the engine of the car is in a cool state. Because the engine overheating means that the pressure of the high-temperature water tank is very high, and this pressure may be trapped in the radiator of the car. Therefore, opening the radiator cover may burn you. In addition, cold water may damage the high-temperature engine. Secondly, open and fix the hood to avoid accidental sliding. Then, gently scrub off the dirt accumulated on the radiator grille with a nylon brush and soapy water. Be sure to clean along the texture of the radiator, not in the opposite direction, so as to avoid metal bending and deformation. After cleaning the grille, drain it with water pipe and rinse it slowly to ensure that all dirt is washed away. Next, the radiator cover consists of a flat metal cover at the top, a small rubber sealing lead at the bottom and a spring connected between them. The tension between the spring and the rubber sealing lead ensures the pressure of the cover, so if they are compressed, the cover can no longer be used and needs to be replaced immediately. Another sign that the cover needs to be replaced is that the rubber sealing lead is rusted or hardened. Usually, the cover needs to be replaced at least once every two years. Next, check the radiator hose and clamp. There are two kinds of hoses: one is at the top of the radiator to drain the hot water tank in the engine; The other is at the bottom, which is used to flush the engine with the water tank. In order to ensure good drainage of the radiator, the hose must be replaced. Therefore, it is best to check whether there are signs of hose cracking, leakage or rust of clamp before cleaning the engine. If the pipe becomes soft or melts, it is better to replace it with a new one. Then, unscrew the small cock and let the coolant flow into the water tray under the car. When all the liquid is discharged, put the small cock back to its original position and put the used coolant into the prepared sealed container with funnel. Then, put the drain pan back under the original small faucet. After that, install the hose on the nozzle and insert it into the water inlet of the radiator until it is filled with water. Then turn on the tap and let the water drain to the plate, and so on until the drained water becomes clean, and then put all the clean water into a sealed container with a funnel. Finally, air that may remain in the cooling system must be exhausted. Cover the radiator and start the engine. Let it run for about 15 minutes. Then turn on the heater and let it work until it gets hot, which will make the coolant start to flow, so that the trapped air will disperse with the flow. Once the gas is removed and there is room for it, more coolant can be put in immediately.
