In daily life, many car buyers will encounter some problems in the maintenance of
New Car. Before sending their beautiful cars to the repair shop for repairs, car buyers do not know the causes. Here are the common
Fuel Car failures. problem.
When a Fuel Car is running at a high speed, the speed reaches 150 kilometers, but the gas is not upshifted immediately, and the speed is already more than 4,000 rpm. I would like to ask what is the reason for this? Reason: When the steam pressure relay fails, the automatic transmission will enter the slope mode and will be forced to drive in third gear. This failure is a pressure adjustment failure. You must go to the store for inspection immediately. First, replace the gearbox oil and try it. Try it. If it continues to lock in the third gear after changing the oil, then the relay needs to be replaced.
While driving, I always feel that the Fuel Car is not cooled enough. I would like to ask if it should be refrigerant? Cause: The most common cause of insufficient refrigerant is a small amount of refrigerant leaking in the system. If there is not enough refrigerant in the air conditioning unit, the amount of refrigerant sprayed from the air conditioning expansion valve to the air conditioning evaporator will inevitably decrease. When the refrigerant evaporates in the air conditioning evaporator, the amount of heat absorbed will also decrease, and the air conditioning cooling capacity will decrease. It also decreased. It is recommended to drive the Fuel Car back to the 4S shop or maintenance shop for inspection first. If the inspection result says that there is no need to add it, there is no need to add it, because too much refrigerant is not good.
The temperature warning light of a Fuel Car will come on for a while and then automatically go off. I would like to ask what is the reason for this? Reason: If this happens, it is first recommended to check whether the antifreeze is missing. If there is insufficient antifreeze in the water tank, it should be added to the normal level immediately. Secondly, there will be some natural loss of antifreeze, but the loss will not be too serious. If it is found that frequent refilling is needed in the short term, then the water tank, water pipe, tea kettle and small heating water tank need to be checked to see if there are leaks in these parts.
