How do you change the air filter on a 1999-2003 Ford Windstar?

Answer 1

The air filter is in the large diameter (about 8" across) tube on the right side of the engine - windshield side of the battery.

There's a lever that releases the retainer clip to access the filter inside. ON the top right of the engine there is a oblong black plastic tube (about 6 inches in diameter) with a metal clasp on the top. open it and separate the 2 sides and remove the old air filter and put in the new one. re-connect the tube and close the clasp. I found it helpful to loosen the clamps that hold the rubber gasket just prior to the filter housing. Don't forget to reconnect the hose on the back side of the filter.

On the top of the engine there should be a BIG black tubular looking hose going from the engine to the driver's side of the engine compartment The air filter is inside this. There is a latch thing. lift up on this latch and it will snap open. pull then end that is toward the engine away from the piece that is attached to the side. the air filter sits inside the piece that is on the side of the compartment. pull it out. It does take a little wiggling it around to get it out. MAKE SURE that when you install the filter the "hole" side of the filter should be facing the engine. Hope this helps. If you mean the engine air filter then you just undo the two screws that hold on the air cover box top and lift it up. Pull the filter out and then replace it. Make sure the Accordion look side goes upwards away from the engine. If you mean the cabin air filter then it behind a plastic cover that is on the passenger side engine compartment up under the wiper area of the cowl. Remove the two screws and remove the cover and pull out the filter and then put in a new one. SIMPLE. Good luck. I will base this answer on changing the air filter for a large majority of vehicles. It is a very simple process involving locating the air filter in the engine compartment, unlatching it - or in some cases, removing a few screws, removing the old filter and replacing it with the new one.
