Underhood component-location diagrams for inline-six and V-6/V-8 engines with a numbered legend of fluid reservoirs and service points.
Part of 1978-1979 Ford Bronco Service Procedures
This document is an engine compartment (engine bay) component location diagram showing two overhead-view illustrations: one labeled 'Typical I-6' for inline six-cylinder engines and one labeled 'Typical V-6, V-8' for V6 and V8 engines. Each illustration uses numbered callouts (1 through 12) pointing to the locations of key underhood service items. The shared legend identifies: 1. Radiator filler cap, 2. Battery, 3. Air cleaner, 4. Automatic transmission dipstick, 5. Brake master cylinder, 6. Engine oil filter, 7. Distributor, 8. Engine oil dipstick, 9. PCV valve, 10. Engine oil filler cap, 11. Power steering reservoir, and 12. Windshield washer reservoir and radiator overflow bottle. A reader can use this page to locate routine maintenance points in the engine compartment, fluid fill and check locations (oil, transmission, brake, power steering, washer/coolant overflow), filter locations, and ignition components, for either engine layout. The document itself contains no year, make, model, part numbers, or torque specifications; it was uploaded to a 1978 Ford Bronco gallery and is consistent with a general service-manual underhood orientation page.
