Old car 523li maintenance, share stickers!

August 15, 2024

Hello everyone, 2021 is a new year. There are many friends leaving messages and private messages for the 525li maintenance I sent before, so I am taking advantage of the iron and maintaining the 523li again.
Everyone communicate together!

This is the general list. Please forgive me for not writing well!

I always say that L6 is good, but in my opinion, the motivation is poor, which can only be said to be good feelings.

The old soundproof cotton is really thick!

For all the BMWs at home, I only use Mobil 0w40 for engine oil. I have a double engine, 7 liters

MAN brand filter

This 3m throttle will be disassembled and washed without damaging the coating. Recommended!

This oil cleaner is not bad. You can add it to the engine in advance, and just put the old oil in the back, but BG can only be cleaned at idle speed.

Haute Direct Spray is highly recommended, which has a much higher concentration than Chevron pea additive

Ngk spark plug, the original is from this brand

Comparison between old and new spark plugs, but one thing is good. It lasts longer. My new x3 requires 2w to replace the spark plug.

Bosch’s ignition coil has the advantage of being cheap, but the disadvantage is that the workmanship is not good

air inlet cleaning

ternary cleaning

The rear axle oil must be changed, everyone should pay attention!

Gasoline filter elements, MAN brand must get!

New gearbox oil pan unpacking

German origin

One box of 12 bottles of transmission fluid, 12 liters

Take one out and have a look

Comparison of old and new oil pan

It’s taken down ****!

When you first started cycling, remember that the gearbox with a torque converter must be cycled. What gravity is better than cycling is an excuse to save money. It’s easy to frugal!
