Solenoid valve repair, filter element replacement and quality comparison

The Spring Festival passed in a flash, and before you knew it was already the Lantern Festival.
The O-rings ordered today have arrived, and the solenoid valve is ready to be completely repaired. In addition, the air conditioner had a slight smell recently, so I bought a new filter element and replaced it with it, but it only cost 22 yuan. When I placed the order, I saw an air filter element. It was said that it used imported filter paper. It was also 22 yuan. I took it together.

The fluorine rubber O-shaped seal ring I bought is more resistant to oil and high temperatures than ordinary rubber rings. The outer diameter is 53MM, the thread diameter is 3.1MM, and the size is exactly the same as that of the original car. Look at the price again, 1.05 yuan/piece. The original one costs about 30.

Several solutions were thought of for the sealing of the solenoid valve, and finally it was decided to inject glue. The new solenoid valve is already integrated with injection molding and has no leakage problems.
Note that I inject glue after opening it, and the inside is full.

Avoid glue spillage here. If glue spills, clean it with a cotton swab.

Install sealing ring and lightly coat Toyota vinyl around it.

Tighten the screws to standard torque, plug in the solenoid valve, and the project is completed successfully!
Because I have removed the fixing rivets on the valve body housing, I must pay special attention to the tightening process of the screws. I must tighten them step by step and multiple times. I must never tighten a single screw in place at one time, otherwise installation deviation will be caused. In serious cases, it will cause friction between the valve body and the moving parts inside, and it will not function normally.
At this point, the solenoid valve has been completely repaired. Wait 12 hours for the glue to solidify, and you can use the car normally. The entire cost is more than 2 yuan for rubber rings, and a little Toyota vinyl is 3 yuan, plus freight, the total is 10 yuan
I hope it will be helpful to future riders!
There are already many posts about replacing filter elements, so I won’t elaborate on them. Send some pictures and let’s take a look. The quality of my filter element for 22 yuan this time is really great!

T20 tools are a must-have for Mercedes-Benz riders. I suggest everyone prepare a Xiaofei, which is really much easier.

It looks quite formal.

Compare the workmanship. The one on the left is Man brand, which costs more than 150 yuan at a discount, and the right is goods from Hebei, free of postage for 22 yuan.

workmanship is very good

The internal brackets are also very strong.

60 on the left, 22 on the right

Look at the details of the filter paper, it’s really good. Can you believe it’s only 22 yuan?
I feel that I bought the filter element very well this time, but I am a little worried. At a price of 22 yuan for free delivery, how long can the company last for such quality? The survival and development of an enterprise need reasonable profit support. I hope that national enterprises will get better and better
Finally, I wish you a happy Lantern Festival
