Start by removing engine room No. 2 relay block through the process of unbolting two structures and removing both the relay block and then disconnecting four wire harness clamps. You should start by unfastening the clamp before separating the No. 1 air cleaner inlet from the air cleaner case while also disconnecting the mass air flow meter connector and taking off the wire harness clamp. Start by easing the clamps then unfasten the two bolts leading to air cleaner assembly removal.
