Note when washing the car: the 7 places in the engine compartment dare not rush with water, otherwise the car washing will be destroyed

Because the engine compartment is an open area, the engine will cover a layer of dust on the engine after a period of time, and it looks dirty.

So can I rinse the engine compartment directly with water? The answer is possible, but the premise is to avoid some key parts, such as the risk of problems if they are rinsed with water in the following places.

1. Wire beam, wiring beam plug

There are many wires in the engine compartment, some are responsible for power supply, and some are responsible for transmission signals. The lines are connected by the plug. Some plugs are not waterproof. Entering the interior of the plug into the plug will cause a short circuit. If it is light, it will burn the device and the risk of spontaneous fire. In addition, water will also cause the plug contact to rust, affecting the transmission of signals and currents, which will make the car have various inexplicable incurable diseases, which is difficult to investigate.

In addition, various wire beams should also try not to dip the water, because the surface of the wiring beam will be wrapped around the protective layer, squeezing a lot of wires together, and the gap between the wires is small. There are certain hidden dangers inside the cable beam.

2. Various computer boards

There are many computer boards in the engine compartment, such as ABS and ESP computers, engine control computers, and automatic transmission control computers. These computers have protective cases and waterproof design. However, the plugs connected to the outside world are very afraid of water, and it may cause short circuit and plug corrosion after water. And the water may also penetrate along the wire beam under the action of capillary.

3. Engine air intake

The engine inlet cannot be rushed with water, because this can easily make the water enter the air filter along the air pipe. When the engine is working, this part of the water may be inhaled into the engine.

4. Brake oil pot

Hydrocariax is a hydrophilic liquid. After the water enters the brake oil, the brake oil will be degraded. Although the brake oil is stored in the brake oil pot and the lid is sealed, there is ventilation device inside the lid. When rinse, water is easy to attach near the lid. When you step on the brake, the ventilation device inside the lid is turned on, and the water will enter.

5, battery

It is best not to rinse directly in the battery. Everyone understands the principle. The water is a conductor, and the positive and negative poles of the battery are on the same plane. After the water is flushed with water, it may cause short circuit.

6. Insurance box

There is a insurance box in the car engine compartment. Although the insurance box has a lid, it does not mean that it is not afraid of water at all. Especially the splattered water when rinse is still possible to enter the inside of the insurance box. The structure below the insurance box can be much more complicated. If the water inlet causes corrosion or short circuit, the consequences are also very serious.

7, headlights

There is a ventilation holes behind the headlight shell. Rinse the lamps to the fog of the lampshade.

8. Do not rinse with water in the hot car state

Rinse the engine under hot car is taboo. Because the engine temperature is relatively high, the sudden rinse of cold water will cause the local to cool down rapidly, which may stimulate some components. In addition, the high -temperature ternary catalyst suddenly rinse with cold water may crack, and there are thousands of pieces of this thing.

9. Try to use flowing water as much as possible, do not use high pressure water guns or pinch water pipes

It is best not to spray at a high -speed water flow when flushing the engine compartment. This is easy to splash a lot of water. The water splash may splash to other parts of the water. You are not easy to grasp.

The correct rinse method is actually very simple:

First of all, it is recommended to use a foam cleaner to spray it directly in the engine compartment and wait for a few minutes to disperse the dirt.

Then turn on the faucet, adjust the water volume to the small flow, and flush the foam and dirt with slow flowing water. You do n’t need to pinch the mouth when rinse, so that the water flows out naturally, which can prevent water from splashing.

After rinse, use the condition to dry the water stain with a rag.
