1. Avoid washing with water when hot. When the engine of the manure truck is in a high temperature state, the engine suddenly gets cold, which may lead to deformation and cracking of the cylinder block. In addition, a large amount of water vapor will be generated when washing at high temperature, which may affect the circuit.
2. Try to avoid the fuse box outside the engine and the driving computer. Some Dongfeng septic truck engine compartment on the fuse box will be prompted, the general idea is to avoid high-pressure gun flushing here. Although there is waterproof treatment, the general rain water is no problem, but the pressure of the high-pressure water gun is larger, just in case. Therefore, when cleaning the engine of the manure truck, try to avoid the area of the driving computer and the external safe box.
Although the engine of the manure truck can be washed with water, the use of high-pressure water gun should be avoided as far as possible. If it is necessary to use, it should also avoid sensitive areas.
The more appropriate method should be to use a wet cloth or a soft brush to clean, if the wet cloth and soft brush can not clean, can use a special engine cleaner. Give the engine of the dung cart a bath and choose foam cleaner. Because foaming detergents stay long, they can effectively decompose oil molecules and some die hards. Of course, this kind of cleaner is not so powerful. After cleaning, it's easy to wash it again. Prevent detergent from corroding the engine surface of the manure truck.
The manufacturer of suction truck should remind everyone that the bad way is to wash the engine with high-pressure water gun when the car is hot. Some people think that when the car is hot, it is easy to wash the dirt off the engine. There is nothing wrong with this idea, but it will seriously damage the engine of the manure truck.
