Windshield Washer Pump Replacement


Washer Bottle

Fig. 1

Does the windshield washer pump on your older Cruiser look like the one in Fig. 1? Pump totally corroded or like mine just outright missing? Well I have a simple cheap fix. I located a source for washer pumps that will work for the older Cruiser and maybe any Cruiser. YMMV!

Washer Pump

Fig. 2

  1. The pump I found for $3.75 + shipping is from www.allelectronics.com Search for part CAT# PMP-2. See Fig. 2. This is a press fit type pump and comes with a sealing washer. Since this is a surplus company I can't guarantee they will always have them . (As of 11-16-2005 they were out of stock.) Order two of them so you will have a spare if one fails. Here is how I mounted it to the stock tank.

Drilling Hole

Fig. 3

  1. Remove the stock tank from the inner fender by just sliding it off it's mount. Clamp it in a vice upside down as shown in Fig. 3 and use a 11/32 drill bit to drill a hole where shown. Don't get the hole too close to the edge of the tank where it's curved, or the washer won't seal. Test fit the included washer into the hole then attempt to slide the pump nozzle into the washer. If it's too tight then use a file or Dremel tool to carefully make the hole just a little bigger. Don't rush and remove to much! Test fit often! You want a very firm fit to prevent leaks.

Test Fitting PumpPump Mounted 2

Fig. 4 A & B

  1. In Fig. 4 A & B you see the pump mounted to the bottom of the tank. Lets test our work for leaks before continuing on. Fill the tank with water and let it sit for a few minutes. It should not leak. If it does then empty the tank. Remove the pump and washer. Dry the tank, pump and washer completely. Now lets use our friend Mr. Silicone to seal it all up. Since there is no pressure on this system it will be easy to seal. Just keep the silicone out of the input. I was lucky, mine did not leak.
  2. In Fig. 4 B above you can see the electrical connector and the nipple for attaching the hose going to the spray nozzles. Lets test the pump before we mount it. Get two small clip leads and attach them to the terminals on the pump motor. Make sure they are not shorting. Take the tank to the truck. Sit the tank upright so the leads will reach the battery. These kinds of pumps should not be run dry so put a bit of water in the tank and attach a short length of hose to the small nipple. Now attach the leads to the battery. Water should squirt out the hose. If it doesn't but the motor is running then reverse the leads. If water does squirt out then your almost done! If the motor does not work at all then get your spare motor (you DID order the spare right?) and swap it in.

Wiring the Pump

Fig. 5

  1. Ok now dump the water and take the tank back to the left side and lets connect it for real. Locate the wires from the old pump. On my 2/1971 there are two Blue wires one with a red stripe and one with a yellow stripe. They should already have the proper connectors for the pump. How cool is that? Connect the one with the yellow stripe to the bottom most connector on the pump as shown in Fig. 5 and of course connect the other one to the other connector. Place the pump back on its mount and fill it with washer fluid. Test it out with the wiper washer switch. If it doesn't work then break out the meter. Check fuses first then the switch itself.
  2. Use the old caps to seal it off or try to find a cap that will fit. I'm still looking and currently just use a piece of Saran Wrap and a rubber band. Works great!
