It wasn't an option all 1970-1971 cars came with this, they used a five port washer pump instead of a three port used on 1968-1969 and 1972 and new cars. The headlamp washers came to be in 1969 (they had a separate solenoid and pump mounted on the wiper motor) and in 1970 they added the five port washer pump. This continued to 1971 and then fell by the wayside in 1972.
Actually, in 1971 the latest car to have been equipped with headlamp washers was in the serial number range of 2300. Bezels with holes for the nozzles show up sporadically until in March 71. The rubber hose bundle had the hoses cut off near the radiator support after the washers were discontinued. The 5-port washer head was also gone by March (before vin 13000). Clearly, this all happened during the 1971 model year and was not a 72 model year change.
I think 62 Corvette is correct. My VIN is in the 17000 range and there is no evidence of headlamp washer system at all. It even has (had, I put an electric washer pump on for reliability) the 3 port washer hose connections on the mechanical pump and it looked original.
Thanks for the help Guys. I have a January car the with a vin in the 8000’s. Not sure of the exact number off the top of my head with the 5 port washer and headlamp washers if that helps anyone.
Wiper Motor, Washer Pump and Hoses The windshield wiper motor assembly is were natural silver die-cast material with a zinc-plated motor housing attached. The motor has rubber grommets and is anchored to the firewall with studs, silver-plated nuts with integral washers.
The motor has a silver label with black-lettered part number and date code. Five-port pumps are 5044758 and three-port models are 5044780. The date code is on the second line and has three numbers for a Julian date and a single number for the last digit of the year.
The pump on 1970 and 1971s to at least s/n 12,605 had five ports, while later cars used pumps with only three ports. Original pumps do not have a part number stamped on the lower passenger side; replacements do. On all pumps, the inlet and outlets point the passenger's side of the car, not up or down as on some replacements.
The pump on all years was white plastic that yellows with age. The assembly is held to the motor with zinc-plated indented flanged-head screws. A thin black plastic cover is snapped over the pump and wiper operating mechanism.
On those 1971s that did not have headlamp washer nozzles (from at least s/n in the 3000 range), the five-port pump has two of the ports connected to each other by a short piece of hose. The headlamp washer hoses were in the harness up to vehicles in the s/n 15,000 range, but they are cut at both ends. The cuts for the pump end are near the master cylinder or horn relay, and the other end is cut just in front of the radiator support.
interesting pic. I've never seen the upper nozzle mounted on the horizontal flat surface of the bezel. Cant imagine it would even fit there.
Early bezels did have the lower nozzle on the horizontal flat, as pictured, but the upper was mounted vertically between the light openings. The lower nozzle position was moved to in between the lights as well due to the difficulty in removing the bezel from the earlier position.
just to add to the confusion.
I have judged some early 1969 with the nozzles both on the vertical. Then some later 1969 with the one head light with the nozzles on the vertical then the other side with one on the top vertical and the lower on the horizontal.
From some point in 1969 till the end of headlight washers install the majority were installed with the top nozzle on the vertical and the bottom nozzle on the horizontal.
My 1971 early Sept build had them installed top on the vertical and bottom on the horizontal
This is an unrestored 1970 with the nozzle on the bottom horizontal
