Car Filter Service

Some would argue that regularly inspecting and maintaining the air filter in your car is the next most important maintenance item you can do after changing the oil and checking the air pressure in your tires. The importance of air filter maintenance cannot be stressed enough; it is, after all, how the engine “breathes.” In layman’s terms, the air outside goes into the intake system after dirt, dust, and foreign particulates are filtered. This blocks them from coming in and doing damage to the engine. Therefore, a clean air filter is critical to your car’s performance and fuel economy.
Cabin Air Filter Service
Comparison between dirty and clean air filterThe cabin air filter cleans the air that comes into the interior through the heating, ventilation and air conditioning system. It “catches” dust, pollen and other airborne particulates and prevents them from entering the vehicle, which is important for anyone who has allergies. Recommendations on cabin air filter replacement vary by manufacturer – some suggest every 12,000 or 15,000 miles, others longer. Therefore, it’s important to check the maintenance schedule in your owner’s manual or, as always, give us a call.
Different types of fuel filtersFuel Filter Service
Fuel filters work differently depending on whether your car, truck or SUV runs on gasoline or diesel. In the first case, the filter removes impurities from the fuel before they reach the engine. In diesel-powered vehicles, fuel filters also work to remove water. This is why the quality of the fuel you use has a great affect on the life of your fuel filter. Although most in-tank fuel filters will last 100,000 miles or more, Coho Auto recommends in-line fuel filters should be replaced between 30,000 to 60,000 miles (depending on the age of the vehicle). The best way to tell if your fuel filter needs replacing is to have us pressure test the system – the normal PSI for a fuel-injected vehicle runs between 30 to 60.
Positive Crankcase Ventilation (PCV) Valve Service
While not a filter, the emission PCV valve is another oft-overlooked component that needs to be regularly inspected and replaced. PCV valves route toxic fumes created by the engine back into the combustion chambers. These fumes are then re-burned to improve fuel efficiency and reduce air pollution. The PCV valve ensures that your engine breathes properly and continues to receive the correct amount of airflow. Replacing the emission valve can lead to unnecessary wear on internal parts, reducing the oil and air filter’s life.
The locations, requirements, and configurations of these vary by vehicle type and manufacturer. Consult your vehicle’s owners or give Coho Auto a call for particular replacement intervals and procedures.
