Windshield Washer / Hood Bumper Removal Mod

First off, allow me to say that full credit for this idea goes to deepbluerubi. I greatly appreciate the sharing of this information.

I decided to do the mod myself and wanted to post up a general how-to. I've posted photos below of the important steps. Without further ado:

Parts Needed:

- Dorman (aka: HELP!) Windshield washer nozzle kit. Part #47137
- Approx 5 feet of 5/32 vacuum tubing.
- Dorman (aka: VACU-TITE!) Two of "T" vacuum adapters, 5/32 size. Part #47333

I picked up the washer nozzle kit from Amazon, and the vacuum tubing as well as the T-adapters at my local auto parts store. Total parts cost including tax was about $21.

Of the spray nozzle kit, I only used the two actual nozzles, the two paint protector guards, and the two plastic screws that hold this in place. See the photo just above as I mock-assembled them for reference. The small vacuum tubes, metal clip, and plastic straight adapters were unused in my install.

Before I describe the install, I wanted to mention that I took a can of black spray paint and painted the vacuum T-adapters black. I'm picky like that.

With the parts in hand and the vacuum adapters painted black, it was time to get going on the actual install.

Installation Steps

1) Prop up hood.

2) There are 5 round plastic push-clips that hold the hood heat-liner in place. These need to be pulled out to release the liner.

3) After pulling the heat liner clips, un-prop the hood. Hold the hood up with one hand, lower the hood prop, and with your free hand, slide the hood liner upward (towards the front of the hood). It will easily come loose. Set it down on top of the engine bay. Grab the hood prop and re-prop the hood back up.

*Note* I left the hood liner laying over the engine while working so it could act as a pseudo work bench. If you're worried about damaging it simply pick it up and set it aside.

4) Remove the hood bumpers. They push through from the underside of the hood.

*Note* The bumpers have to be slightly "pinched" from the sides right up against the hood as there are retaining wings (for lack of a better word) which hold it in place.

5) Install the new washer nozzles. Lay the protective rubber on the underside of the nozzle and insert the bottom of the nozzle into the hood. Carefully screw the retaining screw onto the bottom of the nozzle. As you do this, roughly gauge the aiming point to where you want it to spray on the windshield. Get it snug, but not extremely tight. You'll likely have to adjust it after the test-spray step.

6) Take out the vacuum tubing. Connect it onto the bottom of the driver-side new nozzle. I used about 7" of tubing. Cut the tubing when satisfied. This is all that was needed for where I decided to hook up the vacuum connector. (See pic below step 8 for reference)

7) Connect the T adapter to the open end of the vacuum tubing. Use the horizontal part of the T. The other horizontal end of the T should be pointing towards the passenger nozzle, and the bottom of the T should be pointing towards the windshield area.

8) Connect the main chunk of vacuum tubing to the passenger-side nozzle. Run enough tubing to connect to the T-adapter as described in step 7. I left an extra inch or so of tubing to ensure that there was slack for when the hood insulation liner is re-installed.

9) Next up is running the tubing from the bottom of this T down to the factory washer nozzle hose. Again, I left about an extra inch of tubing for flexibility.

10) Insert second T-adapter into the bottom end of the tubing cut in step 9. See this next photo for reference.

11) This is the scary part (lol). Locate the factory washer nozzle. Trace the factory washer line towards the right about 4". You'll see it tucked into a metal clip. I cut the hose right in the middle of where it sat in this clip. You can adjust as needed (best to err towards the right/drivers side for extra tubing if required). You can see the hose tucked into this clip in the photo above.

12) Connect the T-ends of the second connecter into both ends of the factory fluid line.

*Note* Here's what it looks like after everything is connected.

13) Time to test the spray pattern. Lower the hood and go test the spray. It's up to you where you want the two new nozzles to spray on the windshield. I aimed mine directly towards the wiper blades to help them gather more fluid when wiping across the window.

*Note* Trial and error will help you aim. Repeat as required until you get it aimed like you want. Loosen the screw under the nozzle, aim, and re-tighten the plastic screw. After you get the pattern you want, snug the nozzle screws tightly without damaging your hood.

14) Reinstall the hood heat liner. You'll need to lower the hood prop to get it situated back in place. There are six metal "slots" that the liner slides into. One of these slots is where the factory washer line sets, so keep that in mind if it's difficult to get into place. Also pay attention to the notch cut in the bottom of the heat liner that goes around the factory washer nozzle.

15) Once the heat liner is slid back in, re-prop the hood.

15) Re-install the 5 plastic heat liner clips. Simply push them back into the holes through the liner and into the hood.

And that's that! Drop the hood and enjoy.

This is how it looks under my hood after the install was finished. You wouldn't even notice it without having done the install. You have to look closely to see the tubing going up under the heat liner.

I also recorded a video of the nozzles in action. Pardon the wiper blade dragging. It's doing so because the window is super clean from me testing out the aim a few times.

----> Click for video <----

As you can see, because of how far back on the hood the nozzles sit, and because it takes a partial second for the spray to reach full pressure, some of the spray gets on the hood. Not a concern on my end. (Pic below)

Hope this helps!

I have had issues with my 12 JKU washer nozzle since day one. This will be my next project. Many thanks!

That is great. When I read that they went to a 2 nozzle set up on the 2013's my first thought was trivial changes... until I had to clean the windshield. The extra nozzles make the world of difference.

He hasn't been on in almost a year it appears, but mine are still good no issues.
