In FAW-Volkswagen and Volkswagen's models, the engine water temperature tables in the dashboard are designed to show the table for visual goals. From the actual water temperature of 85 degrees Celsius to 102 degrees Celsius, the dashboard of the water temperature table shows 90 degrees Celsius, when the instrument panel water temperature table pointer over 90 degrees Celsius, the actual engine water temperature has exceeded 105 degrees Celsius.
    Engine and air conditioning system, poor heat, resulting in high water temperature will appear the following several symptoms:
    1. In the poor traffic - traffic jams or long idle time, the engine water temperature table shows too high, the electronic fan high speed work time is too long, the engine noise increases, the temperature is too high open air conditioning failure is most obvious.
    2. In the air temperature is too high to open air-conditioning, the idle speed instability is too large, rapid acceleration, the engine has abnormal sound.
    3. Hot car off ten minutes later, when the start is not easy to drive; hot car sometimes automatically turn off the road.
    4. Cold air conditioning and cooling temperature is very cool, hot air conditioning and cooling effect is not obvious; and air conditioning system has a greater resonance buzzing sound.
    5. Hot car idling, air conditioning compressor clutch frequent absorption, or even disconnected, resulting in hot air conditioning is not cooling.
    Daily inspection and maintenance precautions
    1. Check the dust between the condenser and the tank is too much, thoroughly cleaned with high pressure air to ensure that the tank and condenser have good heat dissipation.
    Reminder: usually pay attention to wipe the dust between the condenser and the tank.
    2. In the hot car, check the temperature difference between the upper and lower water tank, if the temperature difference is too large, you need to check the thermostat opening and whether the pump has lost speed failure.
    Reminder: the temperature difference between the upper and lower water tank can not be too big.
    3. After the hot car, check the antifreeze tank on the top of the return pipe back to the water situation, if the backwater is poor or blocked will cause the water temperature is too high.
    Reminder: Do not blindly disassemble and replace parts during maintenance.
