What is the best way to clean the engine compartment? What will happen if the car engine compartment is not cleaned?

The engine is an important component of the car, and it is also very easy to accumulate some dust. For the normal use of the vehicle and the life of the engine, it is best to clean it regularly. Many manufacturers do not recommend using a high-pressure water gun to wash the engine compartment. Let's take a closer look.

What is the best way to clean the engine compartment?

Try to avoid cleaning the engine with a high-pressure water gun.

Although many circuits in the engine compartment are waterproof, many people think that as long as the battery grounding wire of the car is removed before cleaning and some electrical equipment is covered with plastic bags, short circuits can be avoided. Even so, we do not recommend using a high-pressure water gun to clean the engine compartment directly.

In addition, the car must be cleaned in a cold state. Although the engine block is now made stronger, flushing it with water at high temperature will shorten its service life. In addition, high-temperature flushing will produce a large amount of water vapor. If it penetrates into the car's live equipment, it will easily affect the circuit and cause great damage to the car body.

However, in the final cleaning stage, the sludge that has formed can still be rinsed off with clean water, because the cloth cannot wipe it clean. This is two concepts of rinsing with a high-pressure water gun.

What happens if you don't clean your car's engine compartment?

If there is too much dust in the engine compartment, it will easily affect the heat dissipation of the engine and related components. The heat dissipation effect will be poor, and the engine performance will naturally be affected.

If the engine compartment is not cleaned for a long time, a lot of dust will accumulate, which may corrode the circuit, which may cause engine wiring harness failure. In addition, the filtering function of the air conditioning filter will also be affected.

Why does the oil gauge needle change after washing the car?

First, there is the hysteresis of the oil gauge display;

Second, the oil gauge is malfunctioning, and there is grease and dirt on the connection between the float and the oil level sensor in the oil barrel, which prevents the float from floating up and down at will.

Third, the principle of thermal expansion and contraction. When driving a car, it is usually hot, and the external temperature will also affect the oil level in the tank. When washing the car, the outside of the car is not as expected. The outside of the car is cold and contracts, and the oil gauge pointer drops.
