If it’s been a while since you last changed the air filter in your car, it’s probably worth taking a look at. Air filters are a critical part of the system that makes the engine run at maximum efficiency and helps keep everything clean and functional.
In this article, we will take a look at how to change the air filter, what exactly the air filter does, and some steps you can take to pay better attention to when it needs to be done. After all, your car is an investment – might as well take care of it, right?
Air is one of the most critical steps to turning on and operating a vehicle. That said, because air is all around, the filter often stays beyond the line of thought of the average driver. The air is brought in under the hood and blends with the gasoline. The car is started with a spark from the spark plug.
If the air is not clean, dirt and other debris may get into the engine. This can lead to sloppy running and ultimately hurt the performance and longevity of the engine. The job of the air filter is to clean the air before it ever reaches the engine, picking out the particles of dust and debris.
Air filters are part of the general engine process. They are compact, light weight, and incredibly easy to change.
Much like oil changes, there is a semi-set schedule for when to change an air filter. Basically, once per year or once every 12,000 miles for those of you that drive more than 1,000 miles per month. In dirty cities and for those that drive on dirt roads regularly, it won’t hurt you to lower that amount to every 10,000 miles.
Check the filter now and then by lifting up the hood and looking at it. When it’s browning and oddly colored, that means that the filter is getting dirty and is probably nearing the end of its useful life. If you can’t see how any air is going to get through it, the time has come for a filter change.
The biggest thing you’ll notice with a clean air filter is that the engine runs more smoothly. It is able to optimize the gasoline and air coming in, and run at optimum efficiency.
As common sense would point out, the more you drive the dirtier the filter becomes. This is particularly true in cities, and dusty rural areas.
After you’ve noticed that the filter is dirty, head down to a parts store and tell the clerk you need filter for your make and model. Many grocery and convenience stores also have air filters for sale.
Many will have a guide that shows you which filter will fit your car. We always recommend buying the exact one, because others may not fit correctly and thus won’t do their job very efficiently. Once you’ve procured the filter, park your car in a level spot and open the hood. We’re ready to begin.
The car’s air filter is a crucial part of the engine’s system. It helps to keep the airflow at an ideal rate and it keeps dirt and contaminants out of the manifold and valve train.
While it is recommended that the air filter be changed every 10,000 to 15,000 miles or 12 months, it is important to recognize when something is off.
Besides the check engine light coming on, it is important to recognize other signs. This way you will know how to tell if a car’s air filter needs replacing. This allows you to take optimal care of your car. You can use this tool to know exactly whether check engine lights up because of air filter gets dirty or other reasons.
It is a good idea to pay attention to your car’s gas mileage. A dirty air filter will lead to a decrease in fuel efficiency. If your filter is dirty, the engine starts to compensate for the lower amounts of oxygen by using more fuel to maintain power.
You might also notice the engine misfiring. This is especially noticeable when your car is in idle or just starting up. The wrong air-fuel mixture pollutes the spark plugs which causes the misfire.
In the same way, you may notice that the engine sound is funny. When your car is turned on, and in Park, the engine should be humming nicely. If you notice any shaking or vibrating, sputtering or slipping sounds, that is an indication that you have damaged spark plugs as a result of a dirty air filter.
A reduction in horsepower is another sign of a dirty air filter that needs replacing. Your car should respond easily and smoothly when you push on the accelerator. You might also notice jerking movements. Check the air filter.
Another warning sign is if you notice black smoke or even flames coming out of the exhaust.
This happens when an insufficient air supply does not allow the fuel to burn off properly. In this case, the excess fuel burns when it reaches the exhaust system. A mechanic should check this out to make sure there is no other damage.
You might also notice the smell of gasoline. This is what happens when there is not enough oxygen entering the carburetor or fuel injection system of the car. The excess fuel will exit the car through the exhaust pipe. The smell of gasoline becomes very obvious.
Check your air filter and visually inspect it. A clean air filter will appear to be white or off-white. Over time dust and grime will make the color change. It will appear to be dark. It is always a good idea to use a flashlight and check your filter during the day so you can get the best visual inspection.
If you notice that it is dirty, or that you have driven enough miles, make sure to get it changed right away. Simply go to your local auto parts store so that you can purchase the correct air filter for your make and model. If you are not comfortable doing this yourself, schedule an appointment with your local auto mechanic.
Now you know how to change an air filter. Air filters are a small but vital part of keeping your engine functioning better, for longer. The best part is that they generally aren’t account busters and are one part of maintenance that won’t drive you crazy. Additionally, anyone can learn to change an air filter without too much trouble.
