Refrigerated trucks Tidbits: engine air conditioning system cooling water temperature is too bad solutions to problems

Many refrigerated truck drivers or owners sometimes encounter some problems, such as refrigerated trucks, engines and air conditioning system cooling efficiency, resulting in 
high water temperature will appear after some failures, then how do we solve it? 
One problem: traffic jam when long time idling, this time the water temperature refrigerated truck engine violence quickly high-speed electronic fan told the long working hours, 
increased engine noise, air conditioning temperature is too high when you will feel very obvious. How scientific service refrigerated trucks help you save unnecessary expenses. 
Solution: After the first hot car, return pipe backwater Check antifreeze storage tank, if backwater compensation or blockage will cause the water temperature is too high. Note 
that the repair time and do not blindly dismantled for parts. 
Second problem: refrigerated trucks at high temperature air conditioning, unstable idle speed floating too large, hard acceleration, weakness, and abnormal sound engine. 
Solution: The dust is too much between the tank thoroughly cleaned with high-pressure gas tank and the condenser to ensure good heat dissipation. It is important to remove dirt 
from the usual attention to the condenser and the tank between. 
Question three: hot car flameout ten minutes, when starting the car is not easy; when hot car with sometimes automatically turn off. 
Solution: In the hot car, check the temperature difference between the tank and down pipes, if the temperature too much, you need to check the thermostat opening and the speed of the pump if there is a fault throw switch. Note that the temperature difference between the tank and down pipes can not be too large. 
Question 4: cold car air-conditioning refrigeration temperatures cool, hot car air conditioning cooling effect is not obvious; and have greater resonance humming air 
conditioning system. 
Solution: Due to the addition and replacement of antifreeze is not standardized, it will cause the engine clogging waterways and water tank in advance, the phenomenon of high 
water temperature occur. Antifreeze replaced every two years, must be used in replacement and original parts added. Note that: the engine cooling system after the addition of water, or add antifreeze concentration exceeds 60%, and will cause the water temperature is too high.
