This document is a black-and-white exploded/cutaway line drawing of a heater plenum assembly, uploaded to a 1995 Ford Bronco gallery. It illustrates the heater core installation within the HVAC plenum box. Five components are labeled with callout arrows: the plenum assembly (the main housing on the left, shown with attached vacuum lines, actuators, and wiring), the heater core cover (shown lifted/opened upward to expose the core), the heater core assembly (the finned rectangular core shown partially removed from its cavity), the heater core tubes (the two inlet/outlet tubes exiting the side of the core), and the heater core tube to cowl spacer (a block-shaped spacer piece at the lower right where the tubes pass through the cowl). The drawing gives a reader a clear visual reference for how the heater core seats inside the plenum, how the cover is oriented over it, and where the tube-to-cowl spacer fits — useful when replacing a leaking heater core or reassembling the plenum. The document contains no part numbers, torque specifications, model years, or written procedures; it is purely an identification/orientation illustration.
