BillyBob Posted December 20, 2020 Report Share Posted December 20, 2020 (edited) Innocently enough, I began with repair (replacement) of a leaking heater core. A fun job - perhaps for someone else! One who has little interest in removing the heater core and blower assembly ever again, I thought a rebuild of the 57-year old blower motor might be appropriate. So far, so good. While I'm assembling parts, I thought it might be appropriate to take a look at heater hose routing. We all(?) know the Workshop and Parts Manual illustrations are guidelines and best to follow the illustration reference numbers for part numbers. Here's what I've found, Parts Manual Plate 21-1 seems to show formed heater hoses at both engine connections and straight nipples connecting to each of the 2 engine connections. The nipple (item 2101-90, p/n 1691714) closest to the motor center line (almost directly under the radiator surge tank, connecting to the water pump) - on my car - has a 90 degree bend, the other being a straight nipple (item 2101-89, p/n 1548305). I believe the Parts Manual is incorrect in specifying a formed hose (item 2101-74, p/n 1548497X18), connecting to the engine/water pump. The other hose, item 2101-72 (p/n 1548497X3), I believe to be correct when listed as a formed hose. My car is missing item 2101-76, clip (p/n 195407 and its mate - clip, lacer, p/n 526600X1). Simply asked, who has an image/photo of heater hose routing using this clip & clip, lacer that they could share? See attached files for illustration & part numbers.
