Steel wheel with full wheelcover Steel wheel with full wheelcover Remove the wheelcover from the wheel using the flanged end of the wheel nut wrench by inserting the handle and then prying against the inner wheelcover flange. Install the wheelcover on the wheel with the valve stem in the wheel matching the hole in the wheelcover. Push by hand on the outside edges of the wheelcover until it is snapped firmly in place on the wheel. NOTE: DO NOT USE A STEEL HAMMER. If you have the anti-theft locking spoked wheel cover, each wheel cover has a lock bolt behind the center hub ornament. You need a special key wrench (stored in the glove box) to pry this ornament off and to remove the lock bolt. Do not lose this wrench or you will not be able to remove the wheel cover. 197
