5.0L Secondary Air System Diagram - AIR Pump, Bypass/Diverter Valve Locations

This document is a labeled component-location diagram for the secondary air injection (AIR) system on a 5.0L engine, titled "5.0L Secondary Air." It consists of two engine illustrations. The left illustration shows the belt-driven side of the engine and identifies the silencer/filter, the air pump resonator, and the air pump itself, mounted low on the front of the engine. The right illustration shows the upper intake manifold area and identifies the dual air control solenoid valve (mounted near the intake), the combination air bypass/diverter (AIR B/AIR D) valve located at the rear/top of the engine with its associated hoses, and the check valves in the air injection plumbing. A reader can use this diagram to locate each major secondary air component on the 5.0L engine when diagnosing emissions or air-injection problems, or when replacing the AIR bypass/diverter valve, solenoid, pump, or check valves. The diagram contains no part numbers, torque specifications, vacuum hose color codes, or explicit model-year information; it is purely a component identification/location reference. A partially visible figure reference code ending in "120-B" appears at the right edge of the page.
