When youWhen trying to open the engine cover of a vehicle, you may feel panic if you find that it cannot be opened, especially if you need to do an emergency repair or replace parts. However, don't worry too much. Usually, this problem is not serious. You can solve it by yourself in some simple ways. This article will introduce how to deal with the situation where the engine cover cannot be opened. How to solve the problem that the engine cover cannot be opened 1. Check the safety lock. When the vehicle is stopped, there is often a safety lock on the engine cover to prevent the engine cover from accidentally opening while driving. If the safety lock is not opened, it will not open even if you pull the engine cover easily. The position of the safety lock is usually at the top of the engine cover. You can find some openings or buttons to open the safety yellow lock. If you can't find the safety lock, you can check the vehicle user manual to find the location.Two. Checking the handle of the engine cover is often ignored, and if there is a problem with this part, it will make it difficult to open the engine cover. You need to check the handle carefully to see if there are any problems such as looseness or disconnection of the wire. If you find such a situation, you can manually move the handle wrench to open the engine cover. This situation can be solved by yourself. When you need to buy replacement parts, go to the after-sales maintenance station to buy them. 3. Lubricate the engine cover. If you haven't opened the engine cover for a long time, it is likely that it will not be opened smoothly because of rust. In this case, you can apply some lubricating oil yourself, wait for a few minutes, and then try to open the engine cover. If you find stubbornness, you can use tools such as pliers to help open the engine cover. Four. Use force. If you have checked the safety lock and handle, and used lubricating oil, but the engine cover still cannot be opened, you need to use a little force.Before talking about this method, I need to warn you and be careful. If you don't use the force carefully, it will cause the engine cover to be deformed, thus damaging the entire vehicle. Before using this method, it is best to try other methods. If it is determined that the force must be used, at least you need to find the pressing position of the engine cover, put the force in the correct position, and then open the engine cover as smoothly as possible. 5. Find a professional for help. If you have tried all the above methods but still can't open the engine cover, you'd better ask a professional maintenance personnel for help. They have higher professional knowledge and tools to diagnose and solve the problem that the engine cover cannot be opened. It should be noted that the service fee of finding professional maintenance personnel may be relatively expensive, depending on the situation to decide whether you need it or not. Summary generalIn other words, don't panic when you encounter a situation where the engine cover cannot be opened. This is just one of the most common small problems, which can be dealt with by a simple solution. First of all, check whether the safety lock and handle are worn and use some lubricating oil. If you still can't open it after applying it for a long time, you can use a little force appropriately, but be careful, and it's better to seek professional assistance. The solution of the problem is both saving money and worry-free.
