How to wash the engine yourself

Operation of the car is unthinkable without bringing it to the proper appearance. The first thing that comes to mind is washing. This is the easiest and most obligatory way of caring for a vehicle. And periodically it is recommended to wash not only the body and the interior of the car, but also its engine. If everything is clear with the body wash, it contributes to the preservation of the paintwork and improves visual perception, saving the car from road dirt. Why wash the engine, because it still gets dirty quickly?

No one argues that the engine needs to be constantly washed. There are no specific recommendations regarding the frequency of this procedure, but the experience of car owners suggests that it is desirable to wash the “heart of the car” at least twice a year. And it is better if it will be washing the engine with your own hands, because no one takes care of the car better than its owner.

The question of seasonality

do-it-yourself engine wash

Washing the engine is no less important than washing the car body or inside the car.

It is optimal to wash the engine in the spring and autumn season. Washing the engine in the winter is also an acceptable option, but it is problematic because of the cold and less effective, since dirt on the surface of the engine quickly accumulates again. Actually, the dirt in winter is an anti-icing chemistry with which city utilities process the road surface. It gets on the surface of the engine and provokes its corrosion. If all this does not frighten you, and you decide to wash the engine in the winter season, do not forget to dry it thoroughly, as it can freeze and fail.

Question of reasonableness

Is it necessary to wash the engine, as they say about her? First, it is necessary for the motor to "breathe more freely." Seasonal slush and dust create an overheating layer on its surface. Of course, the dirty engine will not boil, but failures in its operation are not excluded.

Secondly, a clean engine is like a clean board, on which any appearance of technical liquid spills will be evident. If there is a leak of oil or antifreeze from under the cylinder head gasket, a layer of dirt will not hide it. And the sooner you find a malfunction, the greater the chance that you will eliminate it with minimal effort and money.

chemistry for washing the engine

To wash the car's motor is best to get special tools.

Before proceeding directly to the process, let's find out how to properly wash the car engine:

  1. Моющие средства. Сегодня при входе в автомагазин от широты ассортимента средств для мойки разбегаются глаза. Чем мыть двигатель автомобиля – дело хозяина. А вот от чего стоит отказаться, мы подскажем. Худший вариант – жидкость для мытья посуды Фейри. Безусловно, жир от тарелок она отмывает хорошо, но никак не машинное масло.
