Air Filter Replacement


Difficulty: Easy
Duration: 15 minutes
How often: Every 15,000 miles

Changing the air filter should be part of any tune-up. Change it every 15,000 miles or once a year. If you live in an especially dusty or dirty area, change it more often.


Air filter test:
Shine a flashlight from the inside out of your air filter. If you can’t see any light or very little light, it needs to be replaced. Change the breather filter and check the PCV at the same time. On most cars, this is a fairly simple procedure.

Things you’ll need from your garage or your local NAPA AUTO PARTS Store:

Flat-Head/Phillips screwdrivers
Adjustable or open-end wrench
New air filter
New breather filter (if so equipped)
Step 1Look under the hood and find the air filter housing.
It will likely be square (on fuel-injected engines) or round (on older carbureted engines) and about 12 in. (30 cm.) in diameter. On older vehicles, it will be in a large round housing on the top of the engine. On newer vehicles, it will be on the end of the large black intake hose opposite the engine mounted on one of the fender wells.

Step 2Remove screws or clamps.
Use a screwdriver to remove the screws or clamps that hold on the top of the housing. If you have an older vehicle with the round air filter housing, remove the wing nut holding the air filter cover and any other clips.

Step 3Remove the old air filter.
Take out the old air filter and clean any dirt and debris from the housing with a clean rag. Be careful that none falls into the carburetor or the intake. Remove the breather filter.

Step 4Install the new air and breather filters.
Replace the air cleaner top. Reinstall the attaching hardware and air intake hose (if applicable).

Important Tips:
When the air filter is out, you should replace the PCV filter as well. It should only take 5 minutes.

Do not forget to protect the engine maintenance “three-filter”

Experienced driver friends all know that cars on the “three-filter” in car use is very important, it is equivalent to the role of the masks that people often use is to block harmful substances into the car essential. Therefore, only ensure that they are clean, car will maintain physical health.

The so-called “three-filter” refers to the air filter, oil filter and fuel filter, and their role in the name suggests, is the filtration and purification into the car engine inside any gas and liquid, and thus play a protective effect on the engine, but also can improve engine efficiency.

Air Filter

Air Filter

Air Filter

The air suspension with a lot of dust, the main component is silicon dioxide, which is a harder material than metal. The installation of air filter can reduce the cylinder, piston and piston rings and other parts of the wear and tear. Cars, if not install it, will increase seven-fold cylinder wear, piston wear increased by 3-fold increase of 8 times the piston ring wear. Therefore, in the modern automobile engine equipped with a carburetor air filter. General clean once a travel 5,000 kilometers. Cleaning should remove the filter element gently pat face, using compressed air machine blowing from the inside out to remove the dust on the core, do not use gasoline or water washing, driving 25,000 kilometers air filter needs to be replaced.

Oil Filter
Internal combustion engine using the process, dust, metal wear and tear, carbon-ching and other mechanical impurities mixed with oil will continue in the same time, the emission of air and burning oil oxidation also make oil gradually produce gelatinous. Mechanical impurities mixed with the resin will form a sludge, which will not only speed up the movement part of the wear and tear, but could easily lead to blockage of asphalt. In order to ensure clean asphalt, engine lubrication system with oil filter. In addition, together with Chi Pu-resistant cleaning agents inside the engine can better guarantee the smooth flow of asphalt. Most of the current car is to install rotary-mounted oil filter, it is only a one-time filters can not be cleaned, it is best to replace the oil at the same time replace the oil filter, otherwise it will affect the oil quality, and general travel 5,000 km to replace one is appropriate.

Fuel Filter

Fuel Filter

Fuel Filter

As the cars in storage and transportation and the filling process will inevitably be mixed with a number of impurities and moisture, these impurities with the fuel into the fuel supply system and the engine cylinder, the cylinder will accelerate the wear and tear of petrol into the fuel pump must be pre – filtration to ensure the gas supply system work properly. At the same time with the Chi Pu-resistant fuel system cleaners results will be even better. Now that the petrol filter is also a one-time use, and its replacement cycle of about 10,000 kilometers in the most appropriate.

Do a good job “three filter” conservation work, for car maintenance and driving safety engine has a very important role, hope that the majority owners will not overlook this aspect.

Maintenance Auto Parts Auto Repair Plant has the following 10 notes

1, fear of “dirty”

Fuel filter, oil filter, air filter, hydraulic oil filters and all kinds of filters, if too dirty, filter effect will lead to deterioration, excessive impurities in the cylinder into the asphalt, the increased mechanical wear and tear, increasing the likelihood of failure; if severely blocked, but also result in vehicles could not work properly. Radiator heat sink, air-cooled engine cylinder block and cylinder head heat sinks, coolers, heat sinks and other parts too dirty, and will lead to bad cooling, the temperature is too high. Therefore, for such “Pazang” parts must be timely cleaning and maintenance.

2, fear of “hot”

Engine Piston temperature is too high, which occurs easily lead to overheating Shaorong hold cylinder; rubber seals, triangle belt, tires and so overheated, easy to premature aging, performance degradation, shorten life; starters, alternators, regulators and other electrical equipment coil overheating, easily destroyed by scrapping; vehicle bearings should maintain an appropriate temperature, such as overheating, oil will soon degenerate, eventually leading to bearing burned, vehicles damaged.

3, fear of “string”

Diesel fuel system in a variety of couplings, drive axle inside the main driven gear reducer, hydraulic control valve block and valve stem, full hydraulic steering gear of the spool and the valve cover and so on, these complexes even parts in After the time of manufacture of special processing, grinding made in pairs, with very sophisticated in the use of life is always in pairs during the use, must not be interchangeable. Number of interaction devices, such as piston and cylinder liner, bearing and journal, valve and valve seats, connecting rod cap and the bulk of tile shaft, etc. After a period of running-in effect, the relative with the good, the maintenance should also be Note that paired assembly, not to each other, “stopping by.”

4, fear of “anti-”

Engine cylinder pad during installation can not hold against, otherwise it will result in premature cylinder pad ablation damage; for some special shaped piston rings must not be mounted against, should be based on the requirements of different models for assembly; engine fan blades is also the direction of installation requirements, the fan normally takes two kinds of ventilation, and suction can not get counter, otherwise it will lead to undesirable heat engine, the temperature is too high; to have the direction of the tire tread, such as herringbone tread tires, installed the ground-prints should be made Herringbone sharp point to the rear to ensure the greatest driving force. And fitted for the two tires, different models have different requirements, can not be free to install.

5, fear of “missing”

In the maintenance of vehicles, some small pieces may be inadvertently leaking containers, and even some people think that does not matter installed or not installed, it is very dangerous and harmful. Engine air lock films, should be installed in pairs, such as the drain valve fitted or absence will result in loss of control and crashed out piston parts; engine connecting rod bolts, flywheel bolts, transmission shaft bolts installed on the cotter pin, locking screw, insurance, films or spring pads and other anti-loose device, once installed drain in use will likely lead to severe failures from occurring; engine timing gear chamber of the oil used to lubricate gears once the nozzle leaking containers, will lead to a serious oil spill area, so that the engine oil pressure is too low; tank cover, oil port cover, fuel tank cap is missing, make sand, dust and other intrusion, increased wear and tear parts departments.

6, fear of “oil”

Engine air filter dry filter paper, hygroscopicity strong, such as stained with oil, easy to make a higher concentration of inhaled gas mixture inside the cylinder, so that the amount of air enough to increase fuel consumption, engine power down, diesel may also give rise to “Speed”; if the triangle tape coated with oil, will accelerate the corrosion aging, while prone to slip, resulting in lower transmission efficiency; brake shoe, the friction plate dry clutch, brake bands, if the dip on oil and vulnerable to spin, the working poor, threatening road safety; starter motors and generators, carbon brushes, etc., piles of oil is a result of poor contact caused by lack of starter motor power, generator voltage is too low. Tire & Rubber corrosion of oil sensitive rubber in contact with oil will soften, or peeling, short-term exposure can lead to abnormal tire damage and even serious damage.

7, fear of “wash”

Some early beginner drivers or repair personnel, may be that all parts need cleaning, in fact, such understanding is one-sided. For the engine air filter paper, in the removal of dust on it when the cleaning can not be used in any oil, just lightly slap their hands or high-pressure air by-pass filter can be blown inside out; for the cortical components, Oil is not suitably clean, simply wipe with a clean cloth can be.

8, fear of “pressure”

Tire pressure if long-term storage and does not promptly turn over the heap, it will deform due to squeezing, affecting service life; air filter, fuel filter paper and filter, such as compression occurs, will have a greater deformation can not play a dependable filter effect; rubber oil seal, triangular tape, tubing, etc. can not be squeezed, or similarly deformed, affecting normal use.

9, afraid of “near fire”

Tires, triangle belt, cylinder water-blocking rings, rubber seals and other rubber products, if the source close to the fire will be easier to aging deterioration or damage, on the other hand may also cause fire accidents. In particular, some diesel vehicles, the winter cold is difficult to start, a number of drivers used torch heating, we must prevent the burn line, asphalt and so on.

10, fear of “duplicate”

Some parts of this should be a one-time use, individual pilot or mechanic in order to save or because they do not understand the “taboo” and re-use, this can easily lead to accidents. In general, the engine connecting rod bolts, nuts, bolts imported diesel fuel injector, cylinder water-blocking ring, seal copper pad, hydraulic system, various types of oil seals, seals as well as important parts of marketing films, split pin, etc. Part demolition, you must replace the new product; for engine cylinder pad, although no damage was found during maintenance, and preferably also replace the new products, because the old product flexibility is poor, bad seals, easy ablation damage, use of time needed to replace the time-consuming effort Therefore, in order to try to change if new is better.

Auto maintenance Who should I choose?

4S shop, auto service chain, the coexistence of the traditional roadside shops, have their own strength and the short,  Auto maintenance Who should I choose?

Consumption patterns are changing quietly

As the saying goes “one-third of repair, seven dependents,” the conservation of conventional motor vehicles can be seen for the car can have a healthy body is essential to gradually mature the owner of the car to their own care is becoming more and more rational . Have a driving experience over the past 20 years Mr. Zhang told reporters that the century 90s when the bus opened, basic vehicle maintenance in the traditional completion of the roadside shops, then no one to tell you what the maintenance time, and completely by virtue of their cars to explore and experience; in 2003 to buy their own private cars, the one-stop shop 4S standards of after-sales service will not only improve security, more nanny-style reminder service, when the maintenance, and the maintenance of the items, there are professional services; and began last year, a friend introduced to allow Mr. Zhang to experience rapid chain of automobile repair services fast fun Paul.  Mr Cheung said: “like my car has been passed through the warranty period , in the yellow hat, turtle Dr. automotive services, such as the driving force for the maintenance of very large chain, where routine maintenance than ordinary cost 4S shops are much cheaper, than the road products repair shop while reassuring, waiting is also a good environment, the most critical is greatly shortened the waiting time. ”

Maintenance of products is the key

Although from the time, the price of automotive service chain model to occupy a certain advantage, but the car is, after all, the bulk of consumer goods, and its parts also have specific characteristics of consumables, as a variety of automotive-oriented brand, car service, automotive service chain and how to solve this problem?

Driving force (China) Automobile chain services manager, told reporters in the Soviet Union, the driving force behind the use of all the various models of the original brand name accessories, such as routine maintenance of oil, air filter, brake oil, gearbox oil is from the unified brand automakers order, that is, the driving force in the automotive maintenance and replacement of 4S shops are the same products.  But the difference is that the current chain of auto body parts service price relative economic, and basic working hours are free of charge, so compared to the price of maintenance here 4S shop charges only 60% ~ 70%.

 And the driving force behind different, Zhengzhou Anji chose yellow hat is well-known brand of automobile supplies. Future generations of their manager Lee told reporters, yellow hat is derived from the Japanese automotive service chain organizations, products used in automobiles for Shell, Mobil, Castrol and other international brands, from the quality of products is completely reliable in terms of and owners in accordance with the different seasons and geographical selection. As for the routine maintenance of motor vehicles in the wearing parts, the yellow hat’s products are specific to different model specifications for the use of accessories, parts can be perfectly matched with the models.  But Lee said future generations, conventional maintenance and general automotive repair services can choose a chain model, in terms of price or time that the owner can reduce the burden, but the depth of the proposed maintenance of the vehicle owner or the choice of car 4S shop.

4S shop quickly to seize the market

 The reason why the rise of car when 4S shop soon in the traditional roadside shops to seize market share because of their professional after-sales service quality waiting environment is also an important factor in winning.  Colleges and universities in the work of a Miss Liu said: “Now people buy a car needs to enhance the quality of life, quality waiting environment is also part of life. Every time after a repair shop from the street and sees the ground, there is room to operate thick layer of oil, but also rarely have a dedicated waiting area. 4S car shops and auto service chain as a result of large-scale, so the aspect of human nature are in place have done, such as the waiting area is equipped with audio-visual system, Internet area such as entertainment, this is generally the owner of one of the reasons to choose. “
