If you are not suffering from long-term haze or rainy weather, generally speaking, car owners will clean the vehicle once every half a month. Of course, the appearance and cleaning of the inner room are one aspect, and the other is to clean the engine compartment .
, however, unlike cleaning the appearance, cleaning the engine compartment is not something that can be done just by saying it. After all, not all the "internals" of each car model are effectively waterproofed, including batteries, engines, and air filters.
If you encounter the following 5 situations, you must never rinse the engine compartment with water:
1. When the car is hot,
Although the cylinder blocks of today's automobile engines are made of die-cast iron or aluminum, they are not as easy to crack as ordinary cast iron. But even so, do not flush the high-temperature engine compartment to avoid shortening its service life. Furthermore, rinsing with water at high temperatures in the engine compartment will produce a large amount of water vapor. If these water vapor penetrates into the circuit and other equipment, the damage to the vehicle can be large or small.
2. Electrical interface
When cleaning the engine compartment, especially for old models, owners must see clearly. The wiring harness interface that has not been waterproof must not be directly washed with water. If there are exposed battery interfaces and other electrical interfaces in the engine compartment, direct water rinsing may cause oxidation and rust of the interface, which may eventually cause poor contact or even short circuit.
3. Replaced the sub-factory headlight assembly
modified the headlights, pry the entire original headlight assembly, and then change it to various high-bright headlights. The sealing of the headlights of the sub-factory factory is often not as good as the original headlights, and fog or water inlet occurs frequently after installation. Therefore, car owners should try not to clean the headlight assembly position with water, and be sure to pay attention to not splashing water on the modified headlights when washing the engine compartment, so as not to enter the headlights and turn into a "goldfish tank".
4. spark plug
spark plug cannot touch water. If the spark plug is stained with water, the car will not catch fire. If the owner replaces a non-factory designated spark plug for the vehicle, there may be some tiny gaps around the new spark plug, and water or vapor can easily drill into the spark plug. What's the result? Everyone understands it.
5. Fuse box
The fuse in the car cannot be stained with water. If it is washed directly with water, it is easy to cause a short circuit and cause the circuit to burn. When cleaning the engine compartment, try to avoid directly rinsing the fuse box with water.
Editor summarizes
In fact, not all car washing stores can handle the job of cleaning the engine compartment. Those who just start to do it without even looking at it are all wrong. If you can't stand the engine compartment being too dirty, it's better to go to the 4S shop to deal with it.
