This document is a two-part exploded parts diagram for the Ford 5.8L EFI (351W) V8 engine, showing both external and internal engine components. The left page ("5.8L External Components") is an exploded illustration with callouts 1–78 covering items such as the water pump, timing cover, oil pan, oil filter and cooler, exhaust manifolds, distributor, EEC sensors (ECT, ACT), throttle body, TPS, EGR valve, PCV system, fuel injection supply manifold, injectors, coil, and upper/lower intake manifolds. The right page ("5.8L Internal Components") shows callouts 1–63 for internal parts including the camshaft, cam bearings, timing chain and sprockets, lifters, pushrods, rocker arms, valves and springs, pistons, rings, connecting rods, crankshaft, main and rod bearings, bearing caps, flywheel, harmonic damper, and oil pump. Each diagram is keyed to a legend table listing item number, Ford basic part number, and description (e.g., 6010 Block Assy., 6250 Camshaft, 6300 Crankshaft Assy., 9424 Manifold — Intake Upper, 12A310 Coil Assy.). The document is useful for identifying part names and Ford part-number groups when disassembling, rebuilding, or ordering parts for a 5.8L EFI engine, such as that found in a 1990 Ford Bronco.
