When the temperature of the water tank is too high, it is necessary to wait until the pointer of the water thermometer drops to a suitable temperature position before turning off the engine. Wrap the water tank cover with a wet towel and slowly turn on the first switch (1/4 rpm or so). After the steam pressure is released, completely open the water tank cover and check whether the water quantity and quality in the water tank and fan belt are abnormal.
If there is insufficient water, slowly add water to the vicinity of the highest mark line. If the water tank leaks or the fan belt is loose or broken, you can call the trailer company and wait for the trailer to rescue you. If necessary, you can also drive the car to the service factory at a low speed after the engine is completely cooled.
