Can the car engine be washed with water?

1, Shanghai Volkswagen, Shanghai GM and other automobile manufacturers will wash the engine assembly with water after assembly to clean the oil residue on the engine surface during assembly. But it must be cleaned with a certain proportion of special rust inhibitor and cleaning agent. Otherwise, the engine surface will rust.

2. The general cleaning methods are as follows:

(1) Connect the vehicle air machine to the air blowing nozzle.

(2) Insert the power connector of the air machine into the cigarette lighter or use a DC converter; But don't start the engine. If the battery voltage is insufficient or too old, you can switch to the DC converter or start the engine.

(3) Open the handle of the hood.

(4) Use an air machine to clean the dirt in the convex strips and concave holes on the inside of the engine compartment cover.

3. Don't clean the hot car. Although the current automobile engine cylinder block is made of pressurized cast iron or aluminum, it is not as easy to crack as ordinary cast iron. Therefore, the owner should try not to clean the headlight assembly position with water, which will cause the circuit to burn out.
