The Skills That Novices Must Learn: How to Repair Car Oil Filter

How to repair the car oil filter? We all know that in the car maintenance, the car oil filter must be replaced and maintained regularly, but some netizens will ask how to repair the oil filter if it is damaged? Today, we will give you advice on this problem. Please see the following content of this article, we hope it will help you.


Ⅰ. What is a car oil filter?


It can remove impurities such as dust, metal particles, carbon deposits and soot particles in oil, and supply clean oil to crankshafts, connecting rods, camshafts, superchargers, piston rings and other moving pairs to lubricate, cool and clean. function, thereby extending the life of these components. If the engine is the heart of the car and the oil is the blood of the car, then the car oil filter is the liver and lungs of the car.


Ⅱ. Why should the car oil filter be replaced regularly?


1. After the car oil filter is used for a period of time, a lot of sludge and metal debris will accumulate on the filter element of the car oil filter, the filtration efficiency will decrease, and the oil pressure passing through the filter will also be greatly reduced. When the oil pressure is reduced to a certain level, the bypass valve of the automobile oil filter will open, and the unfiltered oil will enter the oil circuit through the bypass, and the carried impurities will increase the wear of the parts. Therefore, the car oil filter needs to be replaced regularly.


2. Under normal circumstances, the car oil filter needs to be replaced every 8000km of frequently used cars; if the driving environment is dusty and harsh, the replacement cycle should be shortened, and it is recommended to replace it every 5000km.


Ⅲ. Is it necessary to change the car oil filter when changing the oil?


Every time you change the oil, you must replace the oil filter with qualified quality. The reasons are as follows:


1. If the oil filter of the car is not replaced for a long time, the filter will be blocked due to the deposition of dirt, and the pollutants will flow directly into the engine, which will aggravate the wear of the parts;


2. Only replace the oil without replacing the car oil filter, then the pollutants in the old machine filter will re-enter the fresh oil to circulate, making the oil change meaningless.


3. Compared with the engine car oil filter, the price is quite cheap. It is very necessary to replace the engine car oil filter at this time to better protect our engine car oil filter.


Ⅳ. It is not difficult to distinguish genuine and fake car oil filters, car owners should remember the following characteristics of high-quality car oil filters:


1. Appearance of high-quality automobile oil filter:


(1) The font on the surface of the shell is clearly printed, and the surface paint texture is good;


(2) A protective bag is installed before leaving the factory, and the interface is lubricated with butter to protect the seal in good condition;


(3) The sealing material of the gasket is good, and the rubber parts are regular.


2. The structure of high-quality automobile oil filter:


(1) There is a bypass valve inside to ensure a sufficient amount of oil supply in any state;


(2) It has the design of suppressing backflow to ensure that the oil required for the next start is stored in the oil filter of the automobile and reduce cold start wear.


3. Material of high-quality automobile oil filter:


(1) The material density of filter paper is moderate to ensure excellent filterability and service life;


(2) The shape standard of the metal oil-passing net in the filter element ensures the passage of oil.


Fake and shoddy car oil filters not only affect the normal oil supply and lubrication of the oil pump to the engine, but also cause oil leakage, poor engine heat dissipation and other faults at the interface of the main oil passage due to poor sealing, and even cause cylinder explosion in severe cases.
