autometer water temp gauge reading high

The autometer water temp gauge reading high , maybe lack or improper selection of coolant: unable to take away the heat generated by engine parts in time, resulting in excessive water temperature . Insufficient heat dissipation area: diesel engines match the heat dissipation area of cooling water according to power and load. Since most of the coolant of water-cooled diesel engines comes from water with ethylene glycol, due to the unqualified quality of coolant, a large amount of scale is generated in the heat dissipation pipe, blocking the heat dissipation pipe and reducing the heat dissipation efficiency. There may also be thermostat failure. If the thermostat fails, the vehicle cooling system may not be able to carry out a large cycle, resulting in a rise in water temperature . Also Cooling fan failure and The injection time of the engine is too late will make the autometer water temp gauge reading high. The specific fault point can only be determined after checking the vehicle.

There are many small pipes on the antifreeze kettle. If the antifreeze leaks due to looseness, we can choose to wrap the damaged pipes with ropes or plastic bags . If it's just insufficient coolant, it's over . Wait until the cooling water temperature drops before adding antifreeze . There is really no coolant , we can also add clean water to replace it temporarily . It should be noted that clean water can only be used for emergency purposes. After the water temperature returns to normal, we should replace it with a new coolant as soon as possible . Besides , it's not the coolant , so check the water tank fan .

If the cooling fan doesn't work , and the cooling fan fails . There is a problem with the cooling medium, and the condensing agent is used up , resulting in the high temperature of the car water tank. The thermostat is damaged. In case of such failure , the car can only be sent to the 4S store for maintenance . Or the water tank fails. Replace the water in the water tank or replace the water tank . If the water pump fails , find a professional to repair it . Check the vehicle body regularly to ensure that there is no dirt around the water tank , which will reduce the heat dissipation capacity of the water tank .
