Can the car engine compartment be washed?

[MacGriffin]

The car engine compartment can be cleaned. Here are the precautions for cleaning the engine compartment: 1. The car's engine compartment undergoes very strict waterproof treatment before leaving the factory. Therefore, many 4S shops or repair shops will directly rinse it with water. It should be noted that you must wait until the car engine cools down before washing, because after prolonged operation, the engine temperature is very high. If cold water is used for rinsing, it may cause the car engine to crack. 2. Do not use a high-pressure water gun to rinse the fuse box. Although the car undergoes waterproof treatment when leaving the factory, facing the high-pressure water gun rinse, the fuse box may leak electricity or short-circuit. 3. After several years of car use, due to aging wiring issues, it is necessary to go to a specialized engine cleaning repair shop for maintenance.
