This is a scanned illustration from a Haynes repair manual (watermarked "© Haynes 80-96") showing the location of the coolant temperature sending unit on Ford 5.0L and 5.8L V8 engines, with a note that other V8 engines are similar. The figure is labeled 9.4b. The line drawing depicts the top of the engine, including the distributor cap with spark plug wires, the oil filler cap, and surrounding hoses and wiring. A callout arrow labeled "TO FRONT OF VEHICLE" orients the viewer, and the coolant temperature sending unit is shown threaded into the intake manifold area near the distributor, drawn in an exploded/lifted position to make its mounting point clear. A reader can learn where to find the coolant temperature sending unit on these V8 engines when diagnosing temperature gauge problems or replacing the sender. The document contains no part numbers, torque specifications, or wiring color codes—only the locational illustration and its caption. The "80-96" watermark suggests the manual covers 1980-1996 model years, which is relevant when applying it to specific vehicles.
