    1971 5 Port Washer Pump...Returning the Favor

    I wanted to post some information with the hope that I could return the favor for countless times this forum has helped me in my restoration adventure.

    A while ago I was searching like crazy to find out as much as I could about the washer pump, break point in 71 from the 5 to 3 port, etc. My February 10, 1971 built LS5 has an after market replacement or repro pump with the black ports...and only 3 of them.

    Well tonight I was digging around in the many boxes of original parts that came with my car....I have no idea how I missed it but lo and behold, there at the bottom of the tote sat the original 5 port washer pump...WITH the 4/5 port bypass hose still installed....I'm in shock that I didn't see this before but I'm hoping the pictures of this can help with someone's research....

    One final note, it appears the original owner sprayed the firewall black with the pump in tact.....my project now, carefully removing the black paint! Thank you to all of the contributors on these forums that make this hobby so informative and fun. Cheers!

    Hi Kyle.
    That is quite a good find.
    I'm curious if you February car had or still might have the 2 pieces of washer hose in the vacuum hose bundle running forward on the driver's side apron?
    They were often still in the bundle at that time but cut short at the core support and around the area of the vacuum reserve tank.
    Regards,
    Alan

    My mid-January car has the 5 port pump, the hoses, and holes in the bezels for the nozzles.

      I'm going to look for exactly that today after work. I know that the headlight bezels do not have the holes but I never paid attention to the hose bundle inside the fender. Thanks for the great information, I'll advise!

        Could someone summarize the running changes during the production?

        I assume through at least m/l 1970: 5 port washer with working headlight nozzles
        Then sometime in m/l 1971: 5 port washer with two ports bypassed, h/l hoses installed but cut short, nozzle holes in the h/l buckets
        Then sometime later: 3 port washer with no remnants of h/l hoses, nozzles or holes?

          You have it right, more or less. There are also running changes to the headlamp bezels which you didn't mention, but Alan alluded to. If we get into that there are also changes to the location of the lower headlamp washer nozzle, but that is another story for another time.

          I don't have all the change points in my head, but I believe this is covered in gorey detail in the TIM&JG. I don't have that here at work either.

            Hi,
            My mid-January 71 car, (6589), has bezels that have both nozzle holes in the vertical surface between the lights, not the earlier bezel that had the lower nozzle on the horizontal surface below/between the lights.
            Regards,

              The TIM&JG states that, on 1971 cars that didn't have headlamp washers, the headlamp washer hoses nevertheless remained in the harness, "but they [meaning the washer hoses] are cut at both ends. The cuts for the pump end are near the master cylinder or horn relay. The other end is cut just in front of the radiator support." I believe this description is a match for Alan's description earlier in this thread. On my February build car, (1) I have a 5 port washer pump, (2) there is no bypass hose, meaning there are 5 hoses connected to the pump, and (3) on the portion of the hose running to the headlamps, the cut is in the bundle near the middle of the driver's side fender. Does that look/sound like one of the variations of known set-ups? Or is something off on my car?

                Your picture shows the hoses cut by the horn relay. That is one of the descriptions in the TIM&JG. I am a little surprised by the lack of a jumper hose on your five-port pump. It would be interesting to know what those extra two ports connect to given that the hoses are cut int he harness.

                  Hi Daniel,
                  Awfully nice close up of the hose colored stripes looking like a 'railroad track'!
                  I too would expect a car with cut hoses to have the short piece of hose for 2 of the washer ports.
                  Wouldn't it have to in order to stop the fluid from shooting out of those 2 ports when the washers are used?
                  Regards,

                    It would have too or washer fluid would squirt all over the engine.

                      I have some egg on my face here. I was really certain there were 5 separate hoses and no bypass, but after reading the comments (which, in hindsight, make a lot of sense), I went back to study a picture I took of the washer pump. It looks like there is a bypass, although between the 1 and 5 ports rather than the 4 and 5 ports. I think I just never spotted it before. Thanks for the input. As an aside, the lack of ignition shielding is due to the fact that the car is a no radio car.

                        Hi Daniel,
                        That makes sense!
                        I'm curious to know if it appears that the short piece of hose on the pump seems to have been made from a piece of one of the hoses that was cut from the bundle on the apron?
                        Does it have a stripe or other markings that might indicate that?
                        Regards,
                        Alan

                        I'm also curious to know how the lack of an antenna was handled on your car.
                        Is there still no antenna?
                        If so, when you look up from below, past the muffler, to the underside of the rear deck do you see signs of a patch or no hole at all?

                          Hi Alan. I can zoom in on the original 3.1MB iPhone picture, but I can't reach a conclusive answer as to a stripe or other markings. I will give it a close look in person in a couple of weeks and shoot you a message on the topic. So much for me still to learn!
                          As for the antenna, for better or worse the original owner had the dealer install an AM-FM radio in "about" 1973. (He was in his 20s when he bought the car, and tells me ticking LS-5 wiped him out financially, and he couldn't afford the radio for a couple of years.) The radio has the knobs with the white imprint of a broadcast antenna and a musical note, rather than the all black knobs which I think were correct for 1971. I recently exchanged e-mails with him on the topic, and he confirmed that the antenna was installed at the same time of course. I may take a look under the car anyway, under the theory that the dealer may have drilled the antenna in a spot different from where a factory installed antenna would go.
                          The original owner managed to save the block off plate for the interior, so I'm left with the following conundrum: I am inclined to pull the 1973 Delco, which isn't currently working anyway, and put the block off plate back -- I think this would be pretty cool. But then I'm left with a vestigial antenna. The car has never been painted, so I'm not sure whether I pull the radio now, or wait until I have all the resources for a proper re-spray. The car currently wears its 44 year old lacquer enamel bumper to bumper, which is far from perfect, but I do like it. No easy answers.

                            Hi Daniel,
                            Thanks for the additional info.
                            The description of the radio knobs make me think a 72+ radio.
                            I'll be interested to hear what you find when you look under the rear deck. I'm always curious about the hole in the rear deck because although it's round as you would expect it also has an additional 'notch' that fits the base of the antenna which I've wondered how was done.
                            A car with it's original paint is pretty rare these days so 'good for you'!

                              I have a February 2nd car, It to has a 5 port pump with jumper.
                              The hoses that are in the bundle are cut on a "angle" at both ends. I feel that it was done this way so the hoses could not be connected to any device.
