Ford 5.0L Secondary Air System Diagram - Air Pump, Silencer/Filter, Check Valves

This document is a labeled parts-location diagram for the secondary air injection (Thermactor/smog) system on a 5.0L Ford engine, titled "5.0L Secondary Air." It contains two engine illustrations. The left illustration shows the front/driver side of the engine and identifies the SILENCER/FILTER, the AIR PUMP RESONATOR (the tube assembly running across the engine), and the belt-driven AIR PUMP mounted low at 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 with its hose routing, and the CHECK VALVES located in the air tubes leading toward the exhaust manifolds. A reader can learn where each secondary air component is physically located on the engine and how the pump, resonator tube, silencer/filter, control solenoid, bypass/diverter valve, and check valves relate to each other for identification, inspection, or replacement. The diagram carries no explicit year or model text beyond the 5.0L engine designation; it was uploaded to a 1996 Ford Bronco gallery and shows the associated air/vacuum hose routing at the combination valve.
