After buying a car, in fact, most of them drive in the urban area, but they seldom drive outside on the highway because of the mask, and they seldom have the opportunity to drive their families out to play. When driving on May Day this year, I took my family out to play. When driving at high speed, I felt that the speed was about 90 or higher. When I was on the throttle, I obviously felt a resonant sound on the soles of my feet, and even felt my heels numb. I didn’t feel so obvious before! Think of the last time I went to maintenance, I saw a Crown Lu put the same problem to change the engine foot, and I didn’t feel anything unusual about my car at that time, so I didn’t take it seriously. Later, I got in touch with the sales consultant when I bought the car in the service area, and he contacted Yifeng’s after-sale maintenance master to call back, asked me in detail about the situation at that time, and asked me about the production date of the car. I was also asked if I felt the foot plate shake when I was on the accelerator, but it would not vibrate if I released the throttle. In short, the professionals asked in more detail, finally determined that my car or the engine foot behind the engine may not buffer well, and my car is also under warranty, you can order a replacement of the engine foot behind the engine for free. Because at that time, Yifeng’s after-sales master told me that there was no hidden safety danger, but this phenomenon did exist, and if I had changed this accessory, it would certainly have been solved, so considering that I was still driving in other places at that time, I asked them to order one of these accessories for me and replace them after I went out to play on May Day. The spare parts to solve the engine resonance arrived around May 6, and then someone specially contacted me after the sale, considering that I had run a lot of mileage on this trip, but it was still hundreds of kilometers short of maintenance time. So I waited these days, thinking about getting enough mileage for maintenance, driving the car to have a good maintenance check, and then solve the problem of engine resonance. After driving for another few days, I was free to drive the car to the Yifeng after-sales workshop this morning, lifted the car for maintenance and checked it, and replaced the rear engine foot that solved the engine resonance. This maintenance or Crown Lufang exclusive Yifeng factory sent engine filter, plus a bottle of Toyota original factory fuel injection nozzle cleaning agent, but does not include air filter element and air conditioning filter, anyway, sent these four years 100,000 km maintenance also saved thousands of yuan, and the home Toyota pure brand 0w20 oil level is relatively OK. During the maintenance, the car rose and checked. Because the temperature was relatively high these days, the air pressure was also high. instead, the maintenance master lowered the tire pressure, probably because it was normally charged when the weather was cool before. now the tire pressure is hot and cold. This time, the maintenance chassis was checked and there was no problem, and the repairman checked the four tires without pins. Later, it took about half an hour to remove the engine foot at the back of the engine, because it was already lunchtime. I had lunch in their canteen at noon, and there was a free working meal for special customers at noon. The chef in charge of the replacement also went to eat. After dinner, I went to the lounge to have a rest for a while. By the time I went to the workshop, the foot of the new engine had been installed in the car. In short, it didn’t take much time to change this thing, and the master who replaced me was still quite quick and skilled. I am very satisfied with the regular maintenance and repair of this store.
I was supposed to arrive at about 10:30, but I had something to do at hand, so I wasted some time. By the time I drove there, it was almost 11:00, but luckily there was someone at the door of the workshop.
When you go, find this maintenance log book specially. If you don’t have this thing to maintain, you still have to spend money. You can enjoy free maintenance only if you use this maintenance book to do maintenance.
Later, I signed the list of the service desk and determined that the maintenance was still using Toyota pure brand 0w20 oil, plus a Toyota original oil filter element and a bottle of nozzle cleaner, in addition, to change the engine foot, and then went to the rest area for a glass of water.
After drinking a glass of water in the rest area, I still have to look at the car, one is to take a look at the chassis tires, and the other is to see what the engine foot looks like.
By the time of the workshop, the engine cover had been opened, and the master in charge of my car was using a special lift to support the car to the special top position.
The front of the car, including both sides, was properly protected, and later, with the operation of the hoist motor, the car was slowly lifted.
If there were more than one person to lift the car with a special lift, it would be very difficult for him to have a chance to see the chassis of the whole car, so it would be more comprehensive to check up.
The spare tire is not of full size, that is, in case of emergency, use it temporarily in case of emergency.
There is a large shield under the engine. Remove it at the beginning.
There is another car on the next lift, and a master is blowing the water tank in front with an air gun. Recently, there are more catkins, and a lot of things have come out with a hammer on it.
The car rose and began to put oil. I remember that some cars used pumping units to pump out the old oil, and Toyota cars were basically released by unscrewing screws.
The tires were checked around each other, but fortunately no cuts or nails were found.
The detached lower guard of the engine is placed on the table, which is not a metal board, but just a piece of muddy water.
However, some of the stones on the tires were picked out by the maintenance master with a screwdriver.
The accessories used for this maintenance are a barrel of Toyota oil, a Toyota oil filter element and a bottle of nozzle cleaner
I saw this thing on Xianyu a few days ago, and I felt that the Toyota fuel injection nozzle cleaner on Xianyu was unreliable.
After the oil is clean, change the oil filter element again.
This is the oil filter element changed this time.
The environment of the maintenance workshop is good, the light is good, and it looks neat.
Later, a barrel of oil was added to the engine, and the engine didn’t use much oil.
When the maintenance is finished, then we will begin to solve the problem of high-speed throttle resonance of the engine. When we remove the foot of the engine behind the engine, we have to find a Jack.
The master used it for about half an hour and finally removed this thing. In fact, there was no problem with the appearance.
There was a free customer working meal at noon. It was two meats and one vegetarian. After eating, I stayed in the lounge for a while and stared at the big screen on a display case for a while.
There are several free drinks at the bar and the environment is relatively comfortable
Later, when I went to the workshop, it was almost installed
Later, it was confirmed that the new one had been installed
The workshop was still relatively stuffy at noon, and the master who worked for me did not rest and kept installing it.
The engine air filter element and air conditioning filter element are not very dirty when removed. After cleaning and installing it this time, they should be replaced for the next maintenance.
Finally, I added the bottle of oil nozzle lotion, and all the projects for today were completed
When I went back in the afternoon, I took a special trip to the Ring City Expressway next to the city, and felt that the problem of high-speed resonance had indeed been solved
