Automotive engine and air conditioning system, poor heat, resulting in high water temperature will appear the following fault phenomena:
1, in the traffic jam, or long time idling, engine temperature table shows high electronic fan high speed long working hours, the engine noise increases, the air conditioner temperature too high when the fault is the most obvious.
In 2, when the air conditioner temperature too high, unstable idle speed fluctuation is too big, sharp weak acceleration, engine abnormal sound.
3, hot stall after ten minutes, the startup time is not easy car; car driving sometimes automatic flameout.
4, cold air conditioning refrigeration temperature is cool, hot car air-conditioning refrigeration effect is not obvious; and have greater resonance buzz in air conditioning system.
5, when idling, clutch compressor suction off frequently, or even off, causing the car air conditioning refrigeration.
High temperature solution method for automobile engine:
1, hot, backwater backwater check antifreeze water tank at the upper end of the tube, if return not free or blockage will cause the water temperature is too high.
Warm reminder: do not blindly demolition and replacement parts.
The dust between the 2 Baotou beiben heavy truck parts, check the condenser and the water tank is too much, thoroughly cleaned with high pressure gas, to ensure that the water tank and the condenser has good heat dissipation performance.
Warm reminder: usually pay attention to wipe the dust between condenser and water tank.
3, in a hot car, check the Baotou beiben heavy truck parts water tank water temperature, if the temperature is too high, need to check the thermostat opening and if the water pump speed lost fault.
Warm reminder: water tank temperature difference can not be too large.
4, because of the antifreeze added and replaced is not standardized, will cause the Baotou beiben heavy truck engine parts waterways and water tank advance jam, appear high temperature phenomenon. Antifreeze for two years to replace, in the replacement and add must use the original accessories.
Warm reminder: the engine cooling system to add water, or add antifreeze concentration of more than 60%, will cause the water temperature is too high.
5, air conditioning system in high voltage high pressure; air conditioning refrigerant air conditioning refrigeration or lubricating oil excessive; self-adjusting function of internal failure since the commissioning of air conditioning compressor, high pressure and high; air-conditioning condenser blocked, above fault will increase the load on the engine cooling performance of the consumption of cooling system, the water temperature is too high for breakdown the occurrence of.
