What is the Ford part number for the heater water valve shown in this diagram?

The diagram labels the water valve with basic part number 18495.

What components are identified in this heater hose routing diagram?

The legible callouts identify the WATER VALVE (18495), the HEATER INLET HOSE, and a second valve at the left whose label is partially cropped (ending in '...N VALVE' with a part number ending in '49').

Where does the water valve sit in the heater hose routing?

The water valve (18495) is shown mounted near the firewall area at the top of the routing, with the heater inlet hose running from it down across the engine, which is drawn in phantom lines.

Does this diagram state which year or model it applies to?

No. Within the visible scan there is no year, model, or engine applicability text; the '1970' attribution comes only from the upload filename.

This document is a scanned line-art schematic (apparently from a Ford factory shop manual or parts illustration) showing the routing of heater hoses and related valves in the engine compartment. Three callouts are legible: a "WATER VALVE" with basic part number 18495, a second valve at the left whose label is partially cropped (ending in "...N VALVE" with a partial part number ending in "49"), and the "HEATER INLET HOSE." The drawing shows the hoses running from the firewall/heater area across the engine, with clamps, fittings, and vacuum-style lines routed to the valves; the engine (carburetor/intake area) is shown in phantom/dashed lines in the background. The uploader filed it as "70 Heater hose routing" in a 1972 Ford Ranchero gallery, though the document itself displays no year, model, or engine applicability text within the visible scan area. A reader can learn the general routing path of the heater inlet hose, the location of the water valve relative to the firewall, and the Ford basic part number (18495) for the water valve. Left- and right-edge callouts are cropped, so at least two labels are incomplete.
