This is a scanned GM factory assembly/engineering drawing, number 3965175, titled "Air Conditioning - Hose Routing" for the 1970 Camaro "F" Series (Model 12000, UPC C60, Sheet D5). The drawing is an engine-bay illustration showing the routing of air conditioning hoses on the front of the vehicle. Callouts identify the heater hoses along the firewall, the compressor assembly (with its pulley) mounted on the engine, the air conditioning hose running from the compressor toward the front of the vehicle, and the receiver & dehydrator assembly mounted near the radiator support/core area. An arrow highlights a hose clamp/retainer point on a heater hose. The revision record shows two revisions: 9-26-69 ("REC & DEHYDRATOR RELOCATED", auth 27236) and 2-18-70 ("VALVE DWG REV'D", auth 28744), with a preliminary date of 9-2-69. A black metal strap/bracket (an actual part, apparently an exhaust or receiver-drier clamp) is lying on top of the paper, obscuring part of the upper-left area of the drawing. A reader can learn the correct factory routing and mounting locations of the A/C system hoses and major A/C components for a 1970 GM F-body with air conditioning (RPO C60).
