The students who have passed the exam have their noses upturned, but the students who have not taken the exam are eager to hit their heads against the wall.

"What happened the first time, why was I kicked out of the car by the safety officer halfway?"

Zhang Zhao recalled her first exam process:

"For the first time,"

"It was an accident, when I was on the road, the road conditions were very good, the ghost knew that I was driving, so I caught up with a test car in front of me, I was calm at the time, I knew to keep enough distance from it, and then I thought of a way to overtake it, I can't always follow behind, right?

"Suddenly a dog popped out in front of me, scared the driver, right? I didn't react else, just stepped on the brakes, and then the car turned off...... I still had a chance, but I didn't put it in neutral ......."

Zhang Nan was stunned when she heard it, according to Zhang Zhao's description, this is quite a dangerous driving, she is just a novice, she did not hit the direction randomly, nor did she step on the accelerator to hit it, but stepped on the brakes to make the car stop steadily, and she has performed very well.

What is the ignition of the car if it is turned off and there is no neutral ignition? What is it if you fail the exam?

"Although you are saying it lightly, your performance is good, although there are flaws, but you have improved a lot. It's really a big improvement compared to what you used to be. ”

You must know that when Zhang Zhao first came to practice driving, he directly hit the wind vane, Zhang Nan felt very relieved, and then asked her:

"Let's go, what do you want to eat, let's celebrate. ”

"I don't have time, I really have to rush back to Nanhai City at noon, the unit has received a case, and when I come back next week to take the fourth subject, let's celebrate." Zhang Zhao explained.

Zhang Nan immediately raised his left hand and looked, "It's still early, it's only half past nine, and you are in the car at 12:09...... Ahem, let's go back to the hotel to celebrate. ”

This toss took more than two hours......

At noon, after sending Zhang Zhao away, Zhang Nan returned to the training ground.

The sun was poisonous and hot, but it did not affect the enthusiasm of the trainees to practice. Practicing the car, playing cards, Huang Cuiping first found that Zhang Nan was back.

"Yo,"

"The coach is back,"

"Why is the 0909 car clearly on the air conditioner, but why is the wind hot?"

"Hmm, it's impossible, I'll take a look," Zhang Nan hurriedly walked to the side of the 0909 coach, at this time Liu Xi was sweating like rain, and the water formed by sweat added to the foundation on her pretty face all the way to the tip of her chin.

But even so, Liu Xi still reversed the car with a serious face, is he really not afraid of the heat?

"You,"

"Get out of the car. ”

"Is it comfortable to take a sauna on this hot day?"

Zhang Nan looked at the distressed person and hurriedly drove Liu Xi out of the car.

After Liu Xi got out of the car, he sat in the car and took a look.

paralysis

I was shocked.

The water temperature gauge has been reminding that the water temperature is too high, and on the left side of the dashboard, the water temperature has already climbed to the top!

If you come back later, the car will catch fire.

He quickly turned off the car, hung up neutral, and then beckoned Liu Yuexun and a few boys to come over, pushed the car to the shade, opened the engine cover, and let the car cool there.

Back in the resting shed, he spoke.

"Why, the car is so hot, you don't call me? Everyone is going to be steamed in the car, and if I come back later, everyone can eat pig's head meat." ”

"Hahahaha! Pig's head, my sister's pork head. There was laughter in the crowd.

Zhang Nan glared, "You can still laugh? ”

"Isn't it fun to wait until the car catches fire? The temperature is too high, and the car can catch fire at any time, which is quite serious!"

"Liu Xi, you have a score of 100 in subject 1, and there is a red pattern flashing on the dashboard of the car just now, haven't you noticed?"

Zhang Nan nodded Liu Xi's name.

Liu Xi replied while wiping the sweat from his forehead.

"I didn't pay attention,"

"I often hear the sound of 'ding ding ding', I always think that the handbrake is not put in the end, so every time I look at the handbrake, the handbrake is fine, I think it is the seat belt is not fastened, but there is no ah. ”

"You!"

"100 points for nothing. ”

Zhang Nan almost died of anger, he called Huang Cuiping's name again.

"Huang Cuiping, you were the first to notice the problem, did you notice that pattern?"

Huang Cuiping's neck shrank, and immediately buried her head, "Coach......"

"It seems to be a reminder pattern of high water temperature......

She still has her own thinking and judgment.

"But we just rested for twenty minutes, and then the pattern was gone, and I thought it was all right...... It's not ...... right now."

"Is this how you deal with the problems you encounter?" Listening to Huang Cuiping's answer, Zhang Nan coldly glanced at the students.

"Liu Yuexun, didn't you say that you were a teaching assistant?

Liu Yuexun immediately lowered his head in shame.

"I tell you,"

"If there is any prompt in the car, you must immediately stop the car to check and find out the reason, if you can't find the reason, find a professional to deal with it or call me to report, and the car will definitely not be able to drive again. The water temperature of the car was high just now, and there are several possible reasons. ”

"Let's go to the car site now to find out. After speaking, Zhang Nan took the lead and walked to the front of the 0909 car.

While pointing to each device, he explained.

In addition to his students, there were other trainees from the coach car who came up to watch.

"Number one, there's not enough coolant, you see, the refrigerant has slipped a lot past the lowest value, right? At least we need to add refrigerant. ”

"Second, it may be that the cooling fan is faulty, the fan does not rotate, and if the heat is not dissipated, the natural water temperature will rise. ”

"The circulating water pump can fail, the pump leaks, or it doesn't circulate. ”、

"There is also a thermostat failure, and if the thermostat is broken, it can't be sensed. ”

"But now the refrigerant is obviously too low, we have to add the refrigerant first, if after driving for a while, the refrigerant falls again, then the pump is leaking, temporarily may be these two reasons. ”

Zhang Nan beeped so much in one breath, and everyone was listening very carefully.

"Liu Yuexun, a few of you boys, go and fetch me a bucket of water. ”

Liu Yuexun and the others hurriedly went to fetch tap water, and soon three buckets of water were placed in front of Zhang Nan.

"Now that the front of the car has been cold for almost half an hour, I'm going to open the lid of the tank now, but you have to remember that if you open it directly, you're going to be disfigured! Don't do it! Because the temperature inside is still very high, and when you open it, the cryogen inside will erupt like a volcano, and you will be confused. ”

"So, to be on the safe side, it's an hour later, and if you open it like I did, be sure to put a towel over the lid and pour water over it. ”

After speaking, Zhang Nan picked up a bucket of water and slowly poured water on the towel.

"This is to cool down, a bucket of water is not enough, at least four or five pokes are needed, and you guys continue to carry water. He waved his hand and asked Liu Yuexun and the others to run to fetch water again.

After the fifth bucket of water fell on the towel, Zhang Nan beckoned Liu Yuexun to come over again.

"Now you continue to water slowly upwards, and I'll open the lid. ”

Zhang Nan's right hand finally covered the top of the towel and carefully twisted the lid while Liu Yuexun slowly poured water down.

Sneer~

Snort~

The lid was quiet after several consecutive breaths of hot air, and there was no imaginary eruption, indicating that the cooling measures just now had achieved their effect.

"Alright,"

"It's okay now. ”

"All that's left is to put the cryonics in there. ”

"How can you talk about refrigerant liquid...... If it's an emergency, then add mineral water, or add refrigeration, don't hurt the car in order to save a hundred or dozens of dollars......"

At this time, the old driver system finally sounded again.

"Ding,"

"Ding,"

"Ding,"

Three rings in a row, the system must have another reward, it looks like a lot!
