How can we see through the suction truck, sewage truck used engine quality

The engine is the heart of the car. It provides power for the car's movement. It is related to the dynamic nature, economy, and environmental protection of the car. The engine of suction trucks and sewage suction cars is even more important, and it is also related to their work efficiency.

Suction trucks and sewage suction trucks are not easy to use, and the work efficiency is not high. Whether the suction or suction is a force depends mainly on the quality of the engine. The engine quality can reflect the real value of the vehicle to a considerable degree. Especially for the second-hand suction trucks and sewage suction trucks, the detection of the engine is a very professional technique, but learning these three measures guarantees that you can see through the good and bad quality of second-hand engines of suction trucks and sewage suction vehicles at a glance!

First: Open the cover to check the outside of the engine clean, if there is a small amount of oil and dust is normal, such as too much dust, then the vehicle may be more wear, if spotless, you must pay special attention, may be the owner to cover up Some information was carefully cleaned.

The detection of the hood is also a top priority. Inside and outside inspection are very important, especially in the hood, if there is a paint trace inside the hood or spot welding shape, size is inconsistent, then the vehicle is likely to have an accident.

Second: The oil level, color, and cover must be carefully checked. If the oil level is too high, it indicates that the engine is severely radon or leaking.

Oil color detection can be wiped with white paper. If the color is black, it is normal. For other colors, it is abnormal. When checking that there is a flap, the bottom of the cap should be observed after unscrewing the cap. For example, if the bottom of the cap is covered with a thick dark emulsion and a small droplet of water mixed with oil, the engine will not Normally, there may be damage to the cylinder head, cylinder head, or cylinder, resulting in the penetration of antifreeze into the engine oil.

If this happens, the contaminated engine oil may cause damage to the interior of the engine and the engine may need to be overhauled, which has a great impact on the price of the vehicle.

Third, check the engine coolant, battery, and air cleaner. The detection of the engine coolant must be performed while the vehicle is stationary because it is easily burned by the coolant if the vehicle is started. Check if there are any other foreign matter on the coolant surface. If there is oil floating, it means that organic oil may infiltrate inside. If rusted powder is found to be floating, it means that the rust inside the radiator is very serious. This affects the engine. Great.
