The Ford Ranger is available with several different engines, including the 2.3 liter I4, the 3.0 liter V-6 and the 4.0 liter V-6. The process for replacing the Ranger's air filter is the basically the same on all models. Ford recommends replacing the filter every 30,000 miles; however, if you life in a dusty climate you may want to change it more often. To be safe, ask your mechanic or service center to inspect the air filter every other oil change.
Turn your engine off for safety. Open the hood.
Disconnect the air inlet hose from the air filter housing (V-6 Rangers only). Loosen the clamp around the hose, then pull the hose away from the housing.
Flip open the clamps securing the top portion of the air filter housing (four clamps on all models). Remove the filter housing cover.
Lift the old air filter from the filter housing and discard it.
Place the new filter (exposed side down) into the filter housing compartment.
Replace the filter housing cover, and flip down the clamps to secure it.
Reattach the air inlet hose (V-6 only). Tighten the clamp to secure the hose.
