Doubt about whether the car engine can be washed with water

Speaking of car washing, in fact, most of the time we drive into the car wash shop to the clerk. The car owners usually sit on the polo and play with their mobile phones.

Can an automobile engine be washed with water? You will know when you see this

In fact, the exterior of the car is relatively easy to clean, and it is very easy to clean the place where the edges and corners are easy to hide. However, in places where the engine room is full of pipes and lines, static electricity can easily cause dust absorption, and normal refueling and water addition are also prone to oil pollution. In the end, how should we wash it?

Can the engine be washed with water?

For washing engines, there has been a lot of controversy. Some people think that the engine room is not afraid of water at all, because all the equipment in the engine room has been waterproofed. As long as the parts of the engine room can be intact, the owners can take the high pressure water gun or water pipe completely without worry. rinse.

Of course, many people also hold opposing views that today's vehicle fuel injection systems are controlled electronically. The engine compartment also has engine computers, ignition computers, and various sensors and actuators. These electronic components are all controlled by voltage. When it comes into contact with water, it is highly likely that a short circuit will occur, which in turn will damage the engine.

In addition, some people have analyzed more comprehensively. They believe that direct water flushing can easily cause water to remain in the engine. As time passes, it can cause poor contact in the electrical interface, and at the same time, the fastening screws also tend to rust.

The above arguments seem to make sense. In fact, under normal circumstances, the use of low-pressure water guns, and pay attention to some of the pipeline can not enter the water, the engine compartment has been treated with water can also be washed with water, but there are some special circumstances. In the following cases, the engine cannot be washed with water.

1. When the engine temperature is too high, it should not be cleaned.

This is very to explain, the metal thermal expansion and contraction, the engine may cause deformation in cold weather, and then wait for the engine. And it also generates a lot of steam, which may affect the circuit.

2, avoid the fuse box and driving computer

Some car fuse boxes in the engine compartment will be prompted to avoid flushing, water treatment has been done here, but it does not guarantee foolproof.

3, remove debris

When the car is opened for a long time, the engine room will inevitably go in with some leaves, waste paper, snakes, rats, and ants. Therefore, some solid debris must be removed before cleaning to avoid damage to parts.

4, completely shut down after 5 minutes idle speed

The reason why the car is allowed to idle for 5 minutes is because after the engine idles for a while, the temperature of the car will make the grease on the engine softer and thus easier to clean. But if you are worried about the problem of thermal expansion and contraction, you can ignore this one.

It is worth mentioning that, in fact, most of the vehicle's instructions are clearly stipulated: the engine compartment can not be washed directly with water, if it is too dirty, it is recommended to use air to clean.

This is mainly because of the problem of tightness. There is indeed a risk of flushing the engine compartment directly with water. Therefore, direct cleaning of the engine compartment with water is not recommended. You can choose to buy cleaners, take a toothbrush and watering can, which is the most guaranteed engine performance.

The engine room is a place where the main equipment such as an engine, a battery, and a trip computer is placed. Maintenance is very important and care must be taken. For a car, an excellent engine is equal to a healthy heart.
