How do you Replace 1995 previa washer pump?

Answer 1

I just had to do this on mine. The washer pump is attached to the lower front of the washer reservoir. The reservoir is located in the area located below the battery. I had to access it from underneath the van behind the front bumper. It helped a lot to jack up the front passenger side corner of the van. Then you can access it easier from underneath and from in front of the wheel. The first thing to do is to drain the reservoir. I just used a screw driver to pry off one of the hoses attached to the pump and the fluid came pouring out. I lodged a wrench on the nozzle so that the fluid would pour down into a bucket.

Then detach the reservoir from the vehicle. It is attached with 2 bolts on the driver side and 1 bolt on the other side of the reservoir. I also had to undo a small brace that is attached below the reservoir. I undid the one side of the brace I could get to then just gently bent it out of the way. Once you have the reservoir loose you can drop it straight down but you will have to undo the hoses and the power coupling. Press in on the bottom part of the coupling to get it to release.

With the reservoir completely out you can just pop the pump out of the tank. If you are using a original replacement part you could just put the new one in and reverse the procedure.

I didn't have the money to spend on that so I just bought a universal pump. It has a grommet that allows it to fit correctly in the hole. I couldn't find one that had the duel outlet for both the front and back washers so I just hooked up the front washers. The pump cost $16. I had to do a little testing to figure out which 2 of the 3 wires ran from the front washer button. Then I used some electrical connectors that came with the pump that tied the wires from the new pump to the wires above the coupling. That way I could leave the coupling in place if I need it at some future date. I also had to figure out which hose led to the front washers by trial and error.

I did all this by attaching the pump to the tank, putting a little fluid in it and placing it loosely in the area it installs. It had to be close enough that I could make the connections for the tubes and wiring. It was a little messy but I got it done. Once I had the connections made it was just a matter of attaching the reservoir and putting the little brace back in place.
