Vanagon – anticipation of new wiper washer nozzles

I’m on the list for a set of new wiper washer nozzles designed and built by Forrest Whitmore. His samba thread about the nozzles can be found here.

I don’t know of anyone who is really happy with the stock nozzles and the spray pattern they make. And over the years I’ve been less than happy with the washer pump performance. You sort of suspect some amount of voltage drop at the pump making the motor less than perky. I toyed with the idea of adding a new power feed and a relay but I got enough improvement by cleaning the contacts right at the washer switch up on the steering column.

Then the other week I was digging around the mess in the workshop and found a spare washer pump. So I says to myself, “go on, plumb it inline”.

Yeah but… if I was worried about voltage drop in the stock un-relayed circuit with one pump won’t having two pumps in that circuit be pushing things?

Yes.

But I did it anyway. Maybe I’ll put in a relay later, but for now I tapped the G10 terminal on the back of the fuse panel ( its hot when washer switch activated. It’s a feed for the headlight washer system, an option we didn’t get here in North America).

I simply cut the washer fluid tubing right behind the driver’s side headlamp, heated up the cut ends and slipped them over the inlet and outlet of the spare pump. Oh and luckily I had the plastic connector with pigtails so making the electrical connection to pump was easy.


That black boot ain’t quite pushed on enough in the pic below.


So how well does this work with the stock nozzles? You’ll think I’m exaggerating when I say it works twice as good. More volume and force ( it will shoot over the top of the luggage rack if not aimed right) and I’m going through fluid fast. Fast enough that I checked for leaks today. When I get the new nozzles I’ll post some vid comparing things etc.

    Thanks for the link to those new washers! I put myself on the list as well. Never been happy with the spray pattern. I even upgraded to the T3 nozzles, but they still have the fire hose effect.

    With the new nozzles and two motors, you may never have to go to the car wash. 😉

      Hey GT,

      Yeah, I hope the new nozzles do the trick. The second pump is a bit of a lark, easily removed and the lines spliced together, if it’s too much.
      Cheers
