2020 imported [standard axle 525i] 3.7W-kilometer replacement of spark plugs + cleaning of water tank radiator

August 1, 2024

Every time I look at you from this angle, I am filled with joy!~~

I’m here to maintain it. First of all, the three guarantees don’t have much content. Oil filter. I don’t know when the oil of 5W30 was all filled in large barrels. The good bottled oil was changed to a large cup for drinking draft beer + funnel. Let’s go…

The main thing is to replace the spark plug. The maintenance manual requires replacement at 2W kilometers. Most of the friends browsing the forum are replacing it with three guarantees. Follow the large troops and use an artifact first.

Is this the legendary demon-suppressing pestle?

The master of 4S is still very rigorous and serious

These four are ignition coils, right? Don’t criticize Ang. I asked the master if the six-cylinder engine had three on each side. The master said that BMW has an inline six-cylinder three-cannon

Go to battle with the demon-defeating pestle

This is a cylinder, and the second and third cylinders are basically the same as this. There is no oil or water on the head. I think the burning is pretty good. The master said that he was worried that the white ceramic part would fall off due to excessive use. From this point of view, it is still early to burn the white ceramic part. It would be fine to travel another 20,000 kilometers. There are also many BMWs on the forum that travel hundreds of thousands of kilometers. I have never heard of anyone burning the ceramics. Let’s not say if it’s serious, who will sell the new parts to?

There is some coking material on the edge of the fourth cylinder plug

This one is also a four-cylinder one. Looking at it from another perspective, except for some coking substances, there is no major problem. This thing is discharged and burned in an internal combustion steam mechanical cylinder at all times, discharged and burned again. When it is finished, you require people to be clean and clean without oil or water. If you have any dirty things, you can analyze this and that from a technical perspective and technical perspective. Why didn’t you test Tsinghua University and Peking University with this spirit?

The original car is the French champion, and the 4S is Nissan’s NGK. Everyone in the world knows it. I don’t know what platinum or gold it is, but the master said this is the only one.

The next thing that surprised me was the water tank radiator. I thought that the BMW 5 Series air intake grille opened and closed automatically. When it was closed normally, it would isolate the cotton wool, or it would be relatively clean. The result was very unexpected…
