DIY: Windshield Washer Reservoir for the Boosted

Jayhovah

Most of us that are boosted (and probably some CAI) had to delete our washer bottles and have just been living with it.

I've been boosted for a while now and for the most part, I haven't really missed the washer... but from time to time when you really need it, not having it can be annoying. So I made my own... hope this helps someone!

Background:
Conceptually the washer reservoir is a pretty simple thing. It's just a vented container with a hole for the pump, and optionally a level sensor. It can be as simple as grabbing an empty container (water bottles...detergent bottle, etc) and installing the pump into it.

Requirements:
1) Stock location - There is still a good bit of empty space in there and I want to avoid cutting the factory harness to relocate the pump.

2) Keep the level sensor - because.. why not? I'm always trying to keep my car as factory feeling as possible despite all the mods.

3) Be able to fill from the top of the engine compartment.

What you need: (Updated for v2 filler neck)
Level sensor https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Pump https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
1x 3" PVC pipe, about 8.5"
1x 3/4" x 3/4" Male NPT hose barb
1x 3/4" x 3/4" Female NPT hose barb
1x 3/4" NPT Plug
2x hose clamps
2x 3" test/knockout caps
24" 3/4" ID flexible tubing
Aluminum or Steel for making brackets (mine was 3/4" x 1/8")
PVC Cement
Teflon tape

Parts list if building with larger v1 filler neck:


Here is a pic showing the difference between the v2 (smaller) filler neck vs the v1.


Costs: ~$25 for the PVC stuff (can be found at lowes). ~$30 for the new pump and sensor (or just rip out your OE ones). I had the aluminum laying around.

(Note, picture reflects parts for v1 filler neck)



Bottle:

Started out by making a bracket to hold the bottle.. it uses a leftover mount for the OEM bottle.
Here is how I make my brackets.. clamp it down and hit it with a hammer.





Test fit a piece of pipe to make sure it doesn't interfere with the bumper:



Unfortunately it hits the DRL. pre-'13 guys might be able to use this large of a bottle.



Had to cut the pipe and bracket a little shorter.



Test fit with the bumper again - all good!



Resulting size of bracket:



And pipe:



Bore a 1" hole in the pipe close to the edge, ensuring it isn't so close it will interfere with the test cap. If you have a 3/4" NPT tap, thread the hole. I didn't so I just wrapped the barb threads with teflon tape and forcibly threaded it in a few turns. I had originally planned to seal around it with epoxy, but to my surprise this turned out to be water tight.
I used a step bit for all the drilling in this DIY.



Cement in one of the test caps on the barbed end. Make sure you thoroughly scuff and clean the PVC mating surfaces before bonding to ensure a watertight seal. After it cures you can fill in some water temporarily to check for leaks in the cap or around the barb.



Mark where you want to attach the pump (scroll down to see how mine finished out) and bore a 13/16" hole.



Bore a 1 1/4" hole in the other test cap and fit the level sensor. Cement it onto the other end of the 3" pipe.






v2 Filler Neck:

The v2 neck is much simpler, smaller, and frees up the airbox mount for use with something else (like an oil catch can or something). It consists completely of a 3/4" barb with female 3/4" NPT theaded end and a 3/4" NPT plug. Drill a small hole in the plug for venting.

Here is the v2 neck (smaller) in comparison to the v1.


Make a bracket.. needs to be a little larger to clear the rubber sealing trim for the hood (will be obvious in installed pic):



Bracket installed:



Filler in place - I just ziptied it to the bracket to hold it in place:



Instructions if making the larger v1 Filler neck:


Install the pump into the reservoir and zip tie it onto the bracket. Cut the hose from the filler neck to the appropriate length and clamp it onto the barb at the top of the bottle.
Hook up the harness to the pump and sensor. Connect the washer nozzle hose to the pump.



And filled (you can see the fluid in the hose):



It takes just over a quart if you fill all the way up the hose. You need to fill it slowly to allow air to escape.

Enjoy!!! (Feel free to give me a rep if you use this DIY!)



Tools I used:
Step bit for drilling holes
crescent wrench for threading in barbs
320 grit sand paper for scuffing PVC and paint prep
Hammer
Clamps

Quick reference hole sizes:
Barbs: 1"
Pump 13/16"
Level Sensor: 1 1/4"

i still have mine. Why did you have to delete yours? i had to remove the top part. To fix you just cut fill neck and add a small piece of flexable hose and relocate to passenger side fender well. I could of just removed the top part and fill with a long funnel.

I bought an Injen intake without a bottle. I’ll probably do something similar to this rather than spend $100 to get the bottle from Injen.

Updated this to reduce the size of the filler neck and free up the mounting location for an oil catch can. If you wanted to make the v1 neck the info is still there wrapped with "spoiler" buttons.

v2 Filler Neck:

The v2 neck is much simpler, smaller, and frees up the airbox mount for use with something else (like an oil catch can or something). It consists completely of a 3/4" barb with female 3/4" NPT theaded end and a 3/4" NPT plug. Drill a small hole in the plug for venting.

I relocated my res to right next to the bose sub...

I used a res tank and pump that came off of a car in the junk yard. i found one with a tall snorkel to a small tub. i cut the snorkel neck to about 1/2 inch. i epoxy'ed the smaller neck on, using other bits of the plastic to patch some areas.

the path for the hose/electrical was simple.. snip and solder to the oem pump wires, run it along the hood weather strip and into the grommet.. along the door kicker and all the way to the back wall of the unibody (all trim panels have to be pulled.)

I never hooked up the fluid level sensor , and it doesnt give me a light. everything runs fine and i left a space open to install my much bigger setrab power steering cooler

As for the intakes... turbo life never makes thing easy... zzz
