For V6 models with a remote air filter housing, begin by loosening the connecting duct hose clamp. Next, release the tabs or remove the fasteners that secure the two halves of the air cleaner housing, then separate the cover halves and remove the air filter element. Installation follows the reverse order of removal. For vehicles with an integral engine cover/air filter housing, first remove the front engine cover by pulling up the front edge to disengage the front retaining clips and locator pin, then pull the cover forward to disengage the two rear retaining clips. After that, remove the fresh air intake ducts by pulling them off the air filter housing, then lift the engine cover/air filter housing to disengage it from the mounting grommets. Remove the fasteners securing the two filter element covers on the air cleaner housing and take out the air filter element. For four-cylinder models, specifically the 2002 models, the air filter housing is located at the front of the engine compartment, being long and narrow to fit transversely in front of the engine. Start by loosening the air intake duct hose clamp and disconnecting the duct, then release the tabs or remove the fasteners that secure the two halves of the air cleaner housing, separate the cover halves, and remove the air filter element. Installation is the reverse of removal. For 2003 through 2005 models, remove the fasteners that secure the top of the air cleaner housing, separate the cover, and remove the air filter element, with installation again being the reverse of removal.
