1992-96 Ford Bronco 5.8L Thermactor Air Injection Hoses - Exploded Parts Diagram

This is a scanned Ford exploded parts diagram (drawing number P-21187, marked 'Page A, cont'd on Page B') showing the thermactor (secondary air injection) hose routing and related components on a V8 engine, uploaded as applying to 1992-96 Ford Bronco 5.8L trucks. The illustration uses Ford base part-number callouts to identify each hose, clamp, fitting, valve, and bracket. Major callouts include the air pump (9A486), air bypass/control valves (9B466, 9F491, 9B289), hoses and tubes (9A474, 6A664, 9K466, 9G459, 9A487, 9F451, 9S449, 9J435, 9F287, 9B458), check-valve/tube hardware (68890, 5F235, 9G427), hose assemblies 9H300 and 9H467, and fastener/clamp standard part numbers (388497-S8, 390007-S, 38374-S, 386951-S, 383527-S, 45334, 34657-S). Footnote symbols indicate service groupings: '%' items are also serviced in the 9H300 assembly, '▲' items are also serviced in the 9H467 assembly, and '#' items are serviced only in 9H467. A reader can use this page to identify individual thermactor system hoses and clamps by base part number, see how they route between the air pump, valves, and exhaust manifolds, and determine which pieces come only as part of larger hose assemblies.
