Last week I made a post about using the rear wiper function to actuate a sprayer for the IC. Thanks to those who posted. It cleared up a few what-if's.
I purchased the Evolution Motorsports IC sprayer kit a while ago. Pretty easy, simple install, clean out-of-sight switching.
...but I knew there were other ways to make it even kewler.
I de-wipered my hatch...this is the "catch" to this mod". 02+ models need a 01 grommet for a clean "dewiper" job. I posted said p/n in the 337/20AE forums.
The rear washer motor is just a motor. NO PUMP. All pumping is done off of 1 pump at the bottle.
...so I thought, why not pop the OEM feed line off, attach my own feed line and route it where I want? Well, IT WORKS. I just used pieces/parts from the Evo kit. I mean, I paid for it...
Here's the pump off the washer. The black nipple feeds the rear lines (what you want) the white nipple feeds the front (leave that)

As you can see, I've already removed the factory feed line and attached my own tube. You need a decent sized tube. I then attached the blue plastic line to the thicker black line, and you can see the sprayer nozzle.

Since the pump is just above the IC, feeding is a piece of cake.

Drilled out a little hole and used some the Evo sprayer kit grommets.

Not where it ended up, but we test-mounted a few spots. We were trying to find a level area to take advantage of the wide fan spray.
...ended up more on-center, with the feed line actually dropping into the IC area an inch or so. This gave a wide fan spray, and the closeness allowed the water to hit the IC and not really anything else...gravity does the rest of the work and the water trickles through the vanes.

...spraying.

-All done through the factory "rear wiper" sprayer on the stalk.
-Maintains front wiper sprayers...they, just like normal, don't spray/wipe
-Nothing needs hooked up, unhooked.
-Factory pump has it's own crack valve, so no leaking/siphoning out once activated.
-The factory IC shroud is tipped so drainage is fast/clean out the "bottom left" corner space between the shroud and the IC
-Factory rear feed line is just capped and tucked away
-Come winter, just put the motor back, reattach the feed line and tuck away the IC sprayer line.
You need rubber tubing 10", thinner plastic tubing 15", sprayer of some sort, tape, silicone seal...and that's about it.

So lets say the weather is good and you are going out for some fun runs. Why not fill the water tank with a water/ice/alcohol mix for some real cooling power. You would have to keep dumping more ice to keep it fresh though.

For real cheap you could buy a servo and a swich that could make you able to use the wiper OR the sprayer you select. This would work for jetta's and NB's too bad you can disable the wipers too for that time period and just use the stalk as a switch. and with that you don't have to take your rear sprayer off. Just add a stalk from a Home Depot watering kit.

ill have to post my kit up sometime, its similar except i took the lazy way out.
I left the bumper on and fed the tube from inside the engine bay to the right of the ic. From there i used some wire to secure the hose and branched it off with a Y pipe. So i have two misters completely covering the ic

now how come we have to remove the motor for the rear wiper??? couldn't we just leave it and just disconnect the tube that goes to the rear and attach a cap to it, so that dirt doesn't get sucked into the tube??? or pull a fuse to disable the motor??? also we only have 1 tank for the washer fluid right, so that means we would have to drain the tank first correct???

You could, but then you'd have the wiper arm stalk sticking out of the glass. OR you could just pull the electrics and have the wiper arm just sit there idle.
I did remove the feed line to the rear wiper and cap it.
Yes, drain the tank to do this mod. Or just let it dribble out when you pull the pump.
I will be siphoning out the fluid and swapping in chilled water/alcohol for the OhioVW Spring Drags.

i'm kinda confused by what you just said.

so basically the arm would just sit there and be useless, except for when you activate the swinging motion??? i don't mind having the wiper arm back there, it isn't something i'm dying to get rid of... but have a cheap effective freeby sprayer would be cool.
here lets try this, so i will just be taking the hose from the winshield sprayers and rerouting them to the IC and for the rear sprayer i could just cap it off to prevent junk from getting into it. and if i did this the rear wiper would still be functional, in terms of sweeping the glass. is this essentially what you did???

Yes the arm would just sit there. Power and water would be disabled. It would be a dead wiper.
If you left the power hooked up, every time you spray the IC, your wiper would go too.

hmm this is interesting ... what ype of gains could be expected from this?
very large ones or what ?
can the stock intercooler actually handle a decent amount of water/liquid going through it ?

You're not going to get gains, as you'll KEEP power you'd normally lose to heat.
There's not enough volume/flow/pressure to run fluid through the IC. It just gets it wet and excess trickles off.
