AIR Injection & EGR Valve Pipe Routing Diagram - Engine Component Locations

This document is an engine top-view line illustration (schematic/exploded callout diagram) showing the secondary Air Injection Reaction (AIR) system and Exhaust Gas Recirculation (EGR) system plumbing on a V-type engine. Nine numbered callouts identify components on the engine: the AIR system crossover pipe (1) spanning the engine, the left bank AIR check valve (2) and left bank AIR pipe (3), the EGR pipe to the intake manifold (4), the EGR valve itself (5), the EGR pipe from the exhaust manifold (6), the right bank AIR pipe (7), the right bank ignition coils (8, shown as multiple coils mounted along the valve cover), and the right bank AIR check valve (9). A directional arrow at the lower right indicates orientation (likely front of vehicle). From this diagram a reader can learn the routing of the AIR crossover and bank pipes, the locations of both AIR check valves, and how the EGR valve connects between the exhaust manifold pipe and the intake manifold pipe. No part numbers, torque values, years, or vehicle model identification appear on the document itself.
