Preface

Don’t blame me for not writing for a long time. First, I am really busy spitting fire, and second, there is really nothing to write about. I used to change my car to a car before, but I guess there is nothing I can write about my mileage of 25000 kilometers in the past three and a half years. However, there are a lot of strange things in my Chengdu G38 group all day long. I keep the photos and want to write fun together, but he Nai has no time.
Today, there is no more nonsense, happened to meet my big white prompt to change brake oil, 4S prompt to change coolant, more coincidentally, my dear rotten chrysanthemum sales sent me 1K maintenance roll, no need for nothing, just talk about the replacement suggestions and processes of these two things, and talk about the coolant leakage caused by the burst coolant pipe of the B48 engine.

Suggestions for the maintenance of brake oil and coolant

1. Brake oil, brake oil is clearly stipulated in the manual that it must be replaced in 2 years (if I remember correctly), but mine is 3 years and 25000 kilometers, and the car engine system begins to remind us that in fact, we can consider whether or not to replace it according to the testing water content. but there is no equipment to detect water content in general stores, I feel that 4S may not have it. And I have been waiting for three months to change the engine filter before considering whether to change it, more than 300 at a time, this, or this, after all, it is related to the brakes, . (after all, the salesman gave me 1K, hehe.)
2. Coolant, this thing is more expensive. At that time, I saw that more than 300 materials and labor costs were written on the list, which made me think how complicated the process was. It is estimated that we should take some kind of machine to clean it up first, as a result. Hey, it’s a long story. Take a look at the following picture for yourself. It’s not as complicated as the replacement process of brake oil. After reading it, I think I can do it. As for the coolant replacement proposal, I asked the technician (the technician who has a good relationship, don’t YY). He said that the B48 engine generated a lot of heat and had high requirements for the cooling system, so it was suggested that it should be replaced according to the prompt of the engine, but I only prompted it for three and a half years and 25,000 kilometers. I turned around to think about it, and it was okay to change it (after all, the sales iron gave me 1K, hehe).
The above two things, my personal advice is, or according to the maintenance tips to change it, after all, people who drive this car, basically do not lack this 1K, take it easy. For example, for things like spark plugs, the maintenance manual suggests 20, 000 replacement, and the 4S technician told me that 68, 000 is no problem, but I decided to replace 40, 000, and then it will be blown up directly. This kind of things can be delayed to replace, after all, it is not cheap.
3. Add one thing: now BMW officials have changed the maintenance time of the engine filter from 10 months or 8,000 kilometers to eight months or 8,000 kilometers, so I bought a lifetime maintenance for free without hesitation (reluctantly). It cost me 4K, ah. If you don’t buy it once, it’s only 1K. Gnash your teeth and rein in your stomach. Buy it.
My second BMW also gave this thing. When I bought Da Bai, I only gave it 9 times in 3 years. Hey.
Recently, however, my friend mentioned a 530s lead, excluding the interest on the loan, landing 510000. I was completely shocked. Ha. Existence is reasonable, existence is reasonable.

Second, talk about the burst of coolant pipe of B48 engine.

Just say the answer, I asked the technician, he said categorically that the B48 engine burst cold but the liquid tube caused the coolant to leak out of the nest, which is basically the new 3 series! There are very few 5 series. And there are a total of 498 five series in my Chengdu G38 BMW group. I can remember 2 or 3 at most when this happens, and only one can call out a name, and it is still a standard axis import. Haha, Ka Shen, please, I didn’t say you.
So I believed the technician’s answer, and he pointed it out to me for a long time, saying that the 3-series burst return pipe, the 5-series, did not have it at all, and the 3-series burst was due to the plastic material used in the return water pipe, while the two of the 5-series were mixed woven fabrics, so there was no possibility of bursting at all, if there were, there were very few cases. For example, if you go to a place in extremely cold weather, you will immediately go to a warm place to drive intensely. Er, this, this, let’s put our hearts in our pelvis. Ha ha.
Of course, the friends who burst the return pipe should not be depressed. 4S will help you replace the new coolant and a new drain pipe for free. Of course, if you are protecting it, it will help you save money. Talk is better than nothing, ha.

III. Ending

Let’s take a look at your favorite picture and text explanation, below there are coolant and brake fluid replacement mode, really disgusting me, no brake fluid trouble it also charges me 300 hours! Chengdu G38 fifth series car friends, don’t shrunk your mouth, I’m going to write a collection of your crashes, ha, finish work.

I always meet all kinds of magical eldest brothers on the road.

I really want to rush up and get caught and dumped by him. It’s so embarrassing.

I thought this thing was a machine for changing coolant. After all, it charged me 300 man-hours. As a result, it changed brake fluid.

8 the oil that ran for 1000 kilometers is also cola.

I do watch the oil waves.

The most beautiful original factory wheels, do not accept rebuttal! After all, 20 models will be matched simply after that, .

It’s a big bottle of coolant. I photographed it and recorded the model. The technician told me that if I didn’t change it for a long time, the engine would become more corrosive and damage the cooling system because of the sudden cold and heat of the engine. I feel that this is contrary to the chemical way I have learned.

Turn your head and take another picture.

It’s not even 5.5 bottles of oil anymore. It’s a big bottle and half a bottle of small ones.

Five liters, boy.

All right, the brake fluid only needs 1L, or record the model.

The replacement of the family photo, next to a bottle of fuel additives.

This is the box for changing the brake fluid. BMW, your connection is driving me crazy.

It’s in the upper right corner of the engine compartment, just lift the lid.

Take out that machine, pressurized, and put it on the lid.

Then there is a pipe in each caliper, which is connected to the kettle. At first, I thought it was the master’s teapot. I was about to say that the teapot was covered with pulp. I’m sorry.

It’s probably in this position.

Give a close-up. You can also see that the lower hem arm has a perforated weight reduction design

Brake fluid is so clean…

Okay. The master started to tell me about the coolant return pipe, and the one he was referring to was the 5-series return pipe with mixed fabrics.

The material of the heel of the third series is similar to yours above, but the heel of the fifth series is not a return pipe, so there is no risk of cracking, because the joint of the return pipe of this material is the main location of the burst.

Start unscrewing the coolant cap

Get a new oil compartment

Go, go, go, go

What a big bottle

Although these are both coolant pots, the current 525 and 3 Series low-power engines are simply equipped with the small pot on the left, completely cutting off your idea of brushing the system to increase power.
