How do I know if the truck's water pump is broken? You can see from these three

While the howo truck is running, the engine combustion will generate a lot of heat, but the engine temperature should not be too high, otherwise problems such as cracking and deformation, poor oil lubrication and increased wear will occur. will produce, which will shorten the life of the truck engine. Therefore, it is very important to cool the engine. There are numerous cooling water circulation channels in the engine block. Howo water pump VG1500060051 is installed at the upper water inlet of the engine. It is driven by a fan belt, then the hot water in the water channel is pumped out and the cold water is pumped out. Within a certain temperature range.

The engine is most important howo truck parts, the engine cooling water cycle typically has two cycles: a small cycle and a large cycle. When the truck is started, it is in a state of small cycle, so the engine will warm up to about 80 degrees as soon as possible (the set temperature is different depending on the model). When the thermostat is turned on, the truck cooling system goes into a heavy cycle, the engine coolant is quickly cooled through the water tank and radiator to prevent the engine from overheating and malfunctioning.

Among the howo spare parts, the howo water pump VG1500060051 plays a important role. When the water pump fails, it will affect the normal operation of the cooling system. Generally, the water pump exhibits the following symptoms: 1. The howo truck WD615 engine water pump VG1500060051 is connected with the belt to pump cold water out of the water tank to cool the engine. If the water pump has problem, it will directly affect the engine speed, then it will show the problem of unstable speed. This phenomenon Usually, the speed is unstable after starting the car and if the resistance is large, it will even cause the engine to stall. 2. the water pump leak is a relatively common fault, mainly because the gasket is not in place and the engine is leaking near the water pump. A coolant leak will leave colored streaks of coolant on the water pump air vents, leading to symptoms such as high water temperature after running out of coolant. time, when the coolant leaks to the water pump bearing, it will flush the lubricant on the bearing. Causes wear and damage to bearings. 3. If you observe the obvious noise phenomenon of the howo truck water pump in normal time, it is very likely that the water pump VG1500060051 started to be damaged at that time, and the cause of the noise is the internal bearing damage or loose impeller and noise caused by the shaft.
