Vehicles 101: Learn The Filters In Your Car

Have you ever wondered what all the different filters in your vehicle do? Well, you’ve come to the right place. The filters in your vehicle work to keep the bad stuff out and the good stuff in. Each works to help keep a particular compartment of your vehicle clean! Read on for Park Muffler’s guide to vehicle filters.

Oil Filter

The oil filter is designed to remove contaminants from the oil in your vehicle, whether that be engine oil, transmission oil, lubricating oil, or hydraulic oil. By preventing these contaminants and solids in the oil from leaching into the engine, you are saving your engine from decreased efficiency and corrosion.

Fuel Filter

A fuel filter works to prevent any dirt or rust particles in the fuel from getting into your carburetor and fuel injection system. If these substances were to enter the system, they could cause wear and tear, and even failure of the fuel pump due to the abrasiveness of the contaminants. The fuel filter also improves performance, as the less contaminants present in the fuel, the more efficiently it can burn.

Air Filter

The air filter in your vehicles helps to remove dirt particles from the air. This paper filter stops airborne contaminants from getting sucked into your vehicle’s engine. It will inevitably have to be changed as eventually, it will get plugged up. If your air filter is too dirty, your engine won’t be able to get enough air into the combustion chambers, which will cause your vehicle to lose power and run roughly.

Cabin Filter

The cabin filter helps to clean the air that comes into the interior of the car through the heating and conditioning systems. It keeps your ventilation free of harmful exhaust emissions and other air contaminants. If you have allergies, you have your cabin filter to thank for keeping all that pollen, dust, dirt, etc. out of your vehicle! It’s a good idea to get your cabin filter checked at least once a year to make sure it isn’t too dirty. Depending on things like where you drive and how often you drive, you may find that you need to change your cabin filter more or less frequently. Some signs that you might need a new cabin filter are reduced air flow through your heating/cooling system, and/or persistent bad odours.
