The Coolant Ran Out In A Few Days Because The Operating Fluid Was Too Slow And Urgent

  • I have a friend who drives in a transportation company. Because he often runs in the mountains, when he bought the car recently, the new car was equipped with a hydraulic retarder. However, shortly after driving, I found that several of these new cars often need to add the coolant, and the consumption of coolant is also relatively large.
  • At first I thought there was a problem with the quality of the vehicle, people who were looking for service stations and manufacturers. After several times, the problem was still my nephew playing lanterns – as usual, which worried the boss of the transportation company. Until one day, he suddenly found that the drivers of these cars that seemed to have problems were relatively young, or the driving methods were “grumpy”.
The coolant
  • Is the problem of excessive coolant consumption due to the problem of driving method? In order to test his idea, the boss of the logistics company exchanged the driver and the car. The final result was the same as he expected. The drivers were the ones who consumed the coolant.
  • The car is OK. There is something wrong with the driver’s driving method. This is basically certain. So what is the reason? Therefore, he invited the technicians of a liquid buffer manufacturer to solve the problem, and invited me at the same time, so he had such an article.

Driving habits: slow down and pull to  the coolant

  • After a trip with a driver who consumed the coolant, the technician quickly found the problem.
  • The way the driver uses the hydraulic buffer is too rough. Basically, he turns it directly from zero gear to the highest gear. In the operation manual of liquid buffer, such operation method is strictly prohibited for two reasons:
The coolant
  • 1. The use of liquid buffer is equivalent to applying braking force to the drive axle. If the braking force is too large and the grip of the tire is not enough, it is easy to cause the vehicle to lose control.
  • 2. The working principle of liquid buffer is to convert kinetic energy into heat energy, and then dissipate the generated heat into the air through the heat dissipation system of the engine. In the past, there is no way to vaporize the medium and high-grade the coolant, which is easy to produce heat at once, resulting in the sudden increase of the heat consumption of the medium and high-grade coolant in the past.
The coolant
  • It is also the second reason that leads to the frequent reduction of vehicle coolant used by the logistics company, but the problem has not been solved the coolant.
  • According to the instructions for the use of liquid buffer, the following problems should be paid attention to during the use of liquid buffer:
  • 1. Try to use the constant speed gear, let the hydraulic buffer automatically adjust the braking force according to the set speed and the current speed, so as to achieve the purpose of constant speed downhill.
  • 2. When using the hydraulic retarder, remember to increase the braking force step by step. Do not directly switch from zero gear to the highest gear, and do not skip the level and use the hydraulic retarder gear.
  • 3. Select the appropriate gear and let the engine speed reach more than 1600 rpm, so that the heat dissipation system of the engine can effectively dissipate the heat transferred by the liquid buffer into the air the coolant.
The coolant
  • The problem was solved quickly, which the coolant was mainly caused by the improper operation of the driver in the process of using the liquid buffer. After the training of the liquid buffer technicians, the vehicle did not have similar problems. As for whether it is a design defect, we don’t know.
  • But here I have two questions:
  • 1. How much pre-sales training does the manufacturer provide before the vehicle leaves the factory? Or throw a Book of instructions in the car and let you figure it out by yourself.
The coolant
  • I think the basic follow-up problems caused by operation are basically caused by the irresponsibility of manufacturers. The pre-sales training business of domestic car the coolant enterprises really needs to be strengthened.
  • 2. In the process of subsequent use, the old people should also carry out relevant use training for the new people, so as to inherit the good use habits and driving habits.
