In any car (besides electric), air plays a role just as vital as the fuel. The air entering the engine goes through the air filter so that it is free from any foreign particles. This is very vital as any impurities inside the engine can create trouble in the ignition process. Not only that but impurities would increase the wear of the engine and create trouble in smooth operation. That is why all the cars have air filters so that the engine doesn’t have to take the hit and the air entering the engine is absolutely clean and free from any foreign particles. But with time, the air filter tends to collect lot of dirt which affects the performance and efficiency of the car. So it is vital to clean the air filter frequently and replace it at specific intervals. Here is how to change the air filter in your vehicle.
Find the perfect replacement
To change the air filter in your vehicle, the first thing you need to do is find a replacement. If you are not familiar with the kind of air filter that your vehicle uses, consult the user manual or maybe consult the guy form the auto parts store. It is quite possible that there are different air filters offered for your car model. This is because many models have been around for ages and there have been different generations of the same model that vary largely. In such cases, the air filters are also very different along with the other components. Ensure the one you are picking is right for your particular model. The filters might also vary with different engine specifications so keep that in mind as well. Air filters are really inexpensive and so the price difference between different models won’t be huge either.
Firmly secure your car
Park the vehicle properly on level surface and turn off the ignition. Put the park brake in and let the car in gear for manual vehicles. Now find the switch for releasing the hood. This is mostly found below the dashboard and in case you are unable to find it, check the user manual. Open the bonnet using the exterior bonnet release and secure it in its place with the prop rod.
Find the old filter
Find the air filter box inside the bonnet. Often it is a square or rectangular plastic box in front of the car slightly off from the center. The box is usually found near the top for easy access. This box contains the air filter. See how the box is closed. Some of them use just clamps for a quick release while others use multiple screws. You will discover a hose connecting to the air filter box. This hose is secured in its position by a hose clamp. Loosen this clamp a bit to allow for the removal. Now remove the screws of the air filter housing so that the top half can be removed. Place the screws safely in a tray so that they can be easily found later. Remove the top half from its place to reveal the air filter.
Removing and cleaning
The air filter can be made out of different materials like cotton, paper or foam. The periphery would be made out of rubber so that the air cannot escape into the passage without passing through the air filter. Just hold the air filter from the rubber edges and pull it out of its housing. After this clean the air filter housing properly. This is vital as some dirt tends to accumulate in the housing after long usage. You can use a vacuum cleaner on its blower end to blow out all the dirt from the housing. While doing this, make sure you seal the air conduit using self-adhesive tape. This would keep the dirt from making it to the engine while cleaning.
Change the filter
Place the new air filter in the old filter’s place. Ensure the rubber rim around the filter is facing upwards. Also ensure that the edges of filter housing are sealed properly by the rubber rim and there is no gap for the air to escape. Put the cover back in position properly. Make sure it sits flat on the housing and all the points match the original. Fix the clamp/ screws back in place and make sure it is fixed firmly. Slide back the hose in place and tighten its clamp. Close the bonnet and you would have been done.
