n addition to dynamic detection, static detection is also very important in the detection of second-hand dump truck.

When many appraisers detect the second-hand dump truck, the static detection of the vehicle mostly only detects the body and interior, and the static detection of the vehicle engine is often ignored.In fact, in addition to dynamic engine detection, static detection is also very important in the detection of Used dump trucks. Many problems of vehicles can also be found through static detection, and static engine detection is an important part that cannot be ignored.

Dynamic detection of engine is as important as static detection, and many problems can be found in static detection.

Indeed, in the detection process of Used dump truck, the detection of the engine is very important, it is like the heart of the car, so its quality has a great impact on the car price, in the detection process to be particularly careful.For the static test of the engine, some appraisers often ignore, and some people who are new to the second-hand dump truck evaluation, the parts to be tested by the static test of the engine are not very clear, some key parts are easy to miss.To this end, we consulted some senior second-hand dump car appraisers, to understand the engine static testing needs to pay special attention to the parts.

First open the boot cover to check the engine external cleaning, such as a small amount of grease and dust is normal, such as too much dust, the vehicle may wear larger, such as spotless, it should pay special attention to, may be the owner to cover up some information and do a careful cleaning.

Hood testing is also a top priority.Internal and external detection is very important, especially in the engine cover, if the engine cover inside the paint marks or spot welding shape, size is not consistent, that the vehicle is likely to have an accident.

Next, oil plane discretion, color, cap mouth also wants careful check.If the oil level is too high, the engine is serious gas or water leakage.Oil color detection can be wiped with white paper, such as black color, is normal;If other colors are abnormal.In the inspection that there is a cover mouth, to unscrew the oil cap after the observation of its bottom, such as the oil cap at the bottom of a layer of thick dark milk, and oil mixed with small droplets, in this case, the engine is not normal, may be the cylinder pad, cylinder head or cylinder body is damaged, resulting in anti-freeze infiltration caused by the oil.If this happens, the contaminated oil may cause damage to the engine, and the engine may need to be overhauled, which has a significant impact on the price of the vehicle.

Third, check the engine coolant, battery and air filter.Engine coolant detection is required in the stationary state of the vehicle, because if the vehicle starts, it is easy to be burned coolant.Check whether there is any other foreign matter floating on the cooling liquid surface. If there is oil floating, it means there may be oil infiltrating into it.If found rusting powder floating, said the rust in the radiator has been very serious, which has a great impact on the engine.The observation of the battery can check whether there are traces of leakage.The inspection of the air filter can see the quality of vehicle maintenance, if the air filter inside a lot of dust, filter element is very dirty, it means that the vehicle use intensity is large, and the vehicle maintenance is also very poor, the vehicle use intensity is large, poor maintenance of the car, the car condition will not be very good.

Through the static detection of the Used dump truck, also can find a lot of problems of the vehicle, if the detection is careful, the detection result is not less than the result of the dynamic detection, also can have a certain estimate of the car price.When the appraiser tests the vehicle engine, the static inspection is absolutely cannot neglect, moreover must inspect carefully, each step must look carefully.
