    Thumbs up Replacement washer fluid pump "How To"

    So it's been shown before by me and some others but there's not a specific thread on the subject, so here it is.

    Go down to your local Auto Zone and pick up a 9-300 Universal Washer Fluid Pump for about $11.00.

    When you unpack it, you'll see that it has a plastic foot attached to the back end of the pump motor. You'll want to cut it off. Use a dremel with a cutting disk or a simple hack saw. Try to keep the cut close to the body of the motor, so it'll be able to slide thru the rubber boot of the washer fluid bottle.

    Remove your old motor by disconnecting it and sliding it out of it's rubber boot. Now take a small drum sander on your dremmel and Hone out the inside of the rubber boot, making sure to remove the motor retaining lips from both sides of the lip. Hone it out till the new motor will fit in there snug.

    Insert the wires into the rubber tube from the front and pull them through and then force the motor in till the rubber boot just touches the plastic pump part of the pump.

    Connect the tube of the resevoir to the tip of the pump (pointing outwards)
    Connect the tube that goes to the washer nozzles to the other tip that is now pointing down.
    Connect the white pump wire to the Black/yellow wire from the harness
    Connect the Black pump wire to the black wire from the harness
    Make sure to cut off the excess wire so it don't look ugly.

    Slide the resevoir back into its holder and you're done.

    The PO (a Z car restoration specialist) screwed on an aftermarket pump to my washer resevoir. I don't have the rubber.

    Hey Zs-ondabrain. Have you every looked at using a Trico 11-601 instead of a universal model. The 11-601 looks like it's a direct replacement for the OEM washer pump. No need to cut off any mounting stubs.

    My old pump went out on my 77 a couple of years ago. I ended up buying a new washer reservoir w/pump before I found the Trico replacment on Trico's website. Here's their link: http://www.tricoproducts.com/Trico2/pdf/ACF1701.pdf.

    The 11-601 is selling for about $22 dollars on various websites. I always wanted to know if the 11-601 is a an exact replacement. It is listed as a replacement for the 1976-1984 Honda Accord. Anyone out there used the 11-601 and can speak from experience?

    How about rebuilding the old one! the PO always used windshield washer fluid, good thing, because to my surprise the pump is still in working condition ('74 260 Z) but I had thought about taking it appart and servicing it anyway.

    They Are rebuildable. You just have to be careful. The outer shell tabs like to break off. The metal tab on the inside of the propeller typically rusts and no longer allows the motor shaft to turn the prop. It's a small peice about 1/4" x 1/8" x ?? the thickness of a business card? So you can see how easily a small peice of metal will rust and break.

    ordered and installed the Trico 11-601 pump today. got it from Amazon.com ($22).
    the pump body is a direct replacement, virtually the same even down to the wire placement.
    comes with 2 male spade connectors, have to change the ground wire terminal to hook up.
    also, had to switch the hose routing. unless i had the damn thing reversed (VERY likely) from the last time i tried to rebuild it.
    pissers work like new.

    Hey mlc240z. Great to hear that the Trico 11-601 is a direct replacment. Wished I found the part before spending $117 dollars at the dealer for a replacement washer reservoir w/pump.

    For any of those of you who may be thinking, Datsun does not show the pump as a replacement part by itself. They make you buy the whole reservoir and pump. Now you can buy a plug & play replacement for a whole lot less money.

    As I see it, the only way to solve the problem of a missing rubber mounting sleeve is to hunt the junk yards.

    Too bad you can't whiten the reservoir too, to make it just as new as the pump.

    On a good note, you CAN use brake parts cleaner on the washer reservoir. Just stay clear of the OEM Sticker, it will wipe it clean. I just used the Brake parts cleaner on mine and it it much cleaner, not totally whiter, but cleaner.

    Hey thanks for the tip it worked out great I went to Auto Zone with that number, well they don't sell Trico, but they typed the number in and found the match from TAAP CORP (their part number 5-642), USA made for $14 and change. The only difference I can see the the wires which is easy to fix and the numbers stamped in the side are different. Here are some pictures also the old pump is always on the left.

    I also found this pump that matches with the correct connectors on the wires, but can't find a US distributor to get it.

    Tomo, Versing,

    I had the same issue (no rubber piece) and replaced mine with the same autozone unit Zs used. My repair wasn't as elegant or as good, but it worked OK. I just wrapped the pump with electrical tape to almost the ID of the clip area on the tank, and wrapped some rims on either side. Then I finished off with a couple of wraps around the whole thing. It's a bit wobbly when clipped into place, but it stays.

    Wish I had the rubber thingie.

    OK I made the mod the longest part was waiting for the iron to heat up. I pried the tabs up, melted the solder. On the old pump and the new one. Then I bent the tabs back with the old wires on the new pump and welded it together. Once the soldering iron was warm it took about 3 minutes to do.

    I wish I read this before I bought the other unit with another bad pump Well if any one would like to copy me and needs the old parts I guess I have them forsomeone

    Isolate problem to smaller area > unplug pump, press button.

    : if fuse blows then problem is not on the pump side of the plug

    : if fuse does not blow then problem is on pump side of plug.

    By chance did you when installing the wires make a connection to the body of the pump? If you are making conection to the metal body of the pump it would sort out. Also make sure the wires are connected properly the pump would put extra strain if it was pumping backwards poping the fuse.
