4.2 How to maintain a refrigerated truck ? Refrigerated trucks are increasingly popular, but many people do not know how to maintain them after they buy it, causing problems with the function of the car, and they often need to be repaired. Many people also mistakenly believe that after refrigerated trucks have been washed by heavy rain, they have saved a lot of money for car washing. But in fact, the impact on refrigerated trucks during the rainy days is great, and it is even more necessary to inspect and maintain the refrigerated trucks. Then, let's take a 4.2 refrigerated truck as an example to introduce how to maintain a refrigerated truck.

Regarding the tires of 4.2 refrigerated trucks, not only does slipping often occur on slippery roads, but slipping is also likely to occur when climbing or braking. This will result in a reduction in brake performance. Therefore, it should be noted that tires below 4mm groove must pay attention to their insurance incidents, especially when it is raining. Brake fluid entering the water will cause the brake to malfunction. It is recommended to step on the brakes more when starting, to ensure that there is no problem and then start, to prevent unnecessary danger. In addition, it is also necessary to inspect the circuit of the refrigerated truck from time to time to prevent short circuits caused by water seepage. Of course, for refrigerated trucks, due to the need to transport some fruits and vegetables or frozen foods or even drugs, it is also necessary to pay attention to its environmental health. Similarly, for safety reasons, it is recommended that the battery of the refrigerated truck be inspected every one or two months, mainly because the battery of the refrigerated truck is to help start the engine of the refrigerated truck. Once any problems arise, it will affect the start-up. Therefore, when there is a problem with the refrigerated car engine, if it is not on fire, you can try to check the battery.

4.2 How to maintain a refrigerated truck ? The above is just a brief introduction to the maintenance of refrigerated trucks. If you want to have a longer life expectancy of refrigerated trucks, it is safer to start them. It is very necessary to learn some maintenance knowledge about refrigerated trucks. We often pay attention to its price when we buy a refrigerated truck. In fact, we still need to take care of the functions of each of its links. After understanding it clearly, it is also convenient for future maintenance and maintenance.
