AIR CLEANER HOUSING

REMOVAL- 4.7L
1. Disconnect air cleaner cover-to-air duct clamp (Fig. 8).
2. Disconnect air duct at housing.
3. Each of the 3 air cleaner housing mounting bolts is attached with 2 nuts (an upper nut and lower nut). DO NOT REMOVE BOLTS. To prevent stripping bolts, only remove lower nuts. The lower housing nuts are located under left front inner fender (Fig. 8).
a. To gain access to lower nuts, raise vehicle.
b. Remove clips retaining rubber inner fender shield.
c. Pry back shield enough to gain access to lower nuts.
d. Remove 3 nuts.
e. Remove air cleaner assembly from vehicle.
4. If resonator is to be removed, disconnect breather tube at resonator, disconnect air duct clamp at resonator (Fig. 8) and remove 2 resonator mounting bolts (at sides of resonator). Remove resonator from throttle body by loosening clamp at throttle body.

INSTALLATION - 4.7L
1. Position air cleaner assembly to body and install 3 nuts. Tighten nuts to 10 Nm (93 in. lbs.) torque. To prevent excessive vibration transmitted through housing, the nuts must be properly torqued. Do not overtighten nuts.
2. If resonator was removed: Install resonator and bolts. Tighten bolts to 4 Nm (35 in. lbs.) torque. Tighten clamp at throttle body to 4 Nm (35 in. lbs.) torque.
3. Position fender liner and install clips.
4. Connect air duct at housing (Fig. 8).
