What are the “four filters” in cars?
Just like installing a water filter on a water dispenser can provide clean drinking water, people wearing masks can reduce the invasion of various harmful substances, in fact, cars also have this to protect the safety of passengers and system components. Today, let’s take a look at what the “four filters” of a car are? And how long is the maintenance and replacement cycle of the “four filters”?
The “four filters” of a car are the oil filter, gasoline filter, air filter and air conditioning filter. They are indispensable in the use of the car. The oil filter and gasoline filter are like human lungs. They filter out impurities in the oil and gasoline, allowing the engine to operate normally. The air filter and air conditioning filter are a filter. Without their filtration, no matter how good the car is, it will not go far, and no matter how good the air conditioner is, it will have a strange smell.
1.“Oil filter“
1. What is it?
Also known as the oil filter, it is located at the top front of the engine or under the engine. It is mainly used to filter out debris, colloid and water mixed into the oil during use, and deliver clean oil to various lubrication parts.
2. Replacement cycle?
When the oil filter is used for too long, impurities will block the filter paper holes, affecting the filtering effect, causing foreign matter in the oil to not be filtered and circulate in the engine, damaging the engine. Most oil filters are disposable filters that cannot be removed or washed. It is recommended to replace them every 5,000 kilometers or 6 months. (Or replace according to actual conditions)
3. How to replace it?
When replacing the oil filter, you need to use genuine parts. The lack of a one-way valve will cause blockage and even fire accidents. It is recommended to operate under the guidance of a professional or go to a authorized store for processing.
2、“Fuel Filter”
1. What is it?
Also known as the gasoline filter, it is generally located in the fuel tank or at the oil pipe connection of the vehicle chassis. It is mainly used to filter impurities mixed in the fuel, prevent clogging of the fuel system, especially the nozzle, reduce mechanical wear, and ensure stable operation of the engine.
2. Replacement cycle?
If not replaced in time, the engine may become unstable, poorly accelerated, stalled, or difficult to start. It is recommended to replace it every 40,000 kilometers. (Or replace according to actual conditions)
3. How to replace it?
Since there is a certain pressure in the fuel system, in order to avoid incorrect operation during disassembly and installation, it is recommended to go to a authorized store for replacement.
3、“Air filterr”
1. What is it?
Also known as air filters, most are located in the engine compartment or near the engine. They are mainly used to filter out dust and sand in the air to ensure that sufficient and clean air enters the cylinder, avoiding abnormal wear of the cylinder and piston components, which would lead to deterioration of engine performance and shortened life.
2. Replacement cycle?
If it is not replaced in time, some impurities will enter the engine, damage the engine, and cause problems such as high fuel consumption. It is recommended to replace it every 20,000 kilometers. (Or replace it according to the actual situation)
3. How to replace it?
If conditions permit, you can replace it yourself. Open the air filter cover lock, remove the nut that fixes the cover, pull open the baffle, take out the filter element and replace it. If you still have questions, you can go to a special store to ask professionals or replace it.
3、“Air conditioning filter”
1. What is it?
Also known as the air conditioning filter, it is usually located in the glove box of the co-pilot seat, and is also installed in the lower glass compartment in front of the co-pilot compartment in some models. It is mainly used to filter impurities in the air leading to the air conditioner and provide a good air environment for the passengers in the car.
2. Replacement cycle?
If the air conditioning filter is not replaced for a long time, it will absorb a lot of impurities, causing bacteria to grow and seriously affecting the health of the passengers in the car. For the air conditioning filter, it is generally replaced after 1-2 years of driving. (The specific time depends on the vehicle environment)
3. How to replace it?
When replacing the filter, first remove the left interior panel of the passenger seat, then remove the bottom panel of the glove box, take out the old filter and replace it. (It is recommended to operate under the guidance of professionals)
