In modern cars, the engine compartments are expected to be well protected from contamination. However, if the car is no longer new and has been used in harsh conditions, including off-road conditions, it will not be superfluous to clean the engine. Most often, the radiator becomes clogged, interfering with air circulation, against the background of which the power unit begins to heat up more strongly. A regularly buzzing fan, which is part of the cooling system, can indicate a problem. It is also necessary to remove dirt from auxiliary radiators, they are usually located in the depths of the engine compartment. It is impossible to neglect washing the engine, especially if the age of the car is 5-7 years.
It is not uncommon for Karcher employees to water the engine compartment generously at 150 bar in car washes, but in the process it is easy to harm the electrics, sensors and relays, even though they are protected by shields. There is also the possibility of water getting into the candle wells, and when the generator is flooded, it is easy to harm the insulating material, which threatens to result in corrosion of the diode bridge and serious breakdowns. Before washing the motor, you need to protect the “delicate” elements. A large water pressure is also superfluous, it is better to limit yourself to an indicator of up to 100 bar.
If the driver does not want to wash the engine for fear of damaging the elements, steam can be used. It is served dry at a temperature of 150 degrees, and the pressure should be 7-10 atm. In this way, dirt and oil can be removed, and moisture in the area of electrical contacts will not accumulate. True, such a procedure is usually expensive, at the level of 2 thousand rubles, reports “RG”. The chemical cleaning option is still relevant, some resort to dry cleaning.
