How to Change Cabin Filter in Ford F350by Christian Killian
Clean air is important both for the engine in your F350 and for the passengers inside the truck. The Ford F350 is equipped with a cabin air filter that cleans the dust and particles out of the air coming into the truck through the HVAC system. Like all filters, this one requires periodic maintenance. It should be changed at least every 10,000 miles or once a year. The filter is located behind the dash on the passenger’s side of the truck and can be changed with a single screwdriver. Purchase a replacement filter at any auto parts store.
Locate the cabin air filter access cover under the passenger’s side of the dash. There are five Phillips head screws holding the cover on the air duct that will make it easier to identify.
Remove the five retaining screws from the access cover with a Phillips screwdriver and set them aside. Remove the cover from the air duct.
Locate the plastic tab on the center of the filter just inside the air duct. Grasp the tab and pull the filter straight out of the duct.
Slide the new air filter into the air duct, making sure it locks into position. Be sure the plastic tab used to remove the filter is on the bottom for easy removal in another 10,000 miles.
Position the access cover on the air duct and install the five retaining screws with a Phillips head screwdriver. Tighten the screws until they are secure, being careful not to overtighten them.
