adallak Posted May 3, 2016 Report Share Posted May 3, 2016 Windshield washer reservoir has been losing liquid, so I wrapped the housing of the pump and a few other places with toilet paper to find the leak. The housing of the pump was leaking... I took it apart and snapped a few pictures. That little o-ring inserted in the bottom part of the housing is supposed to seal the shaft of the motor and not let the fluid go up reach the motor. Looks like the o-ring eventually dries out, the motor rusts out and the fluid leaks out of washer housing through the several cut outs in the housing.

adallak Posted May 3, 2016 Author Report Share Posted May 3, 2016 Jim, I have done it twice. Made a working pump out of two bad ones. This time, I just replaced it with a new one. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
cdgrinci Posted May 3, 2016 Report Share Posted May 3, 2016 I had similar problems with my Olds Bravada pump(s); leaking where sealed. I used a couple of tie-wraps to secure the gaskets more tightly (but it appears to be different from the one's you showed); anyway where I'm going with this, it was only a temporary fix (it started leaking again); I got new motors (I think from Amazon).

adallak Posted May 3, 2016 Author Report Share Posted May 3, 2016 I think it's a good idea to use the pump now and then (I do not use it for months) and keep the fluid reservoir half-empty to reduce the hydrostatic pressure on the washer around the shaft of the motor.
