Does anyone know of an eBay supplier of these? I have thought about using a standard washer jet but the stream is too precise.

Agree, about £5 for a box of 4 or 5.
rather then £12 for 1 Subaru jet.

[Davey]

This sort of thing?

Damn fine idea!

Cheers!

Ive ordered the 180 degree sprayers, just need to get a flasher relay to controll the motor and voila!

Well you did ask.........

see http://bbs.scoobynet.co.uk/showthrea...ht=intercooler

or just read :

This has been done a few times, but after witnesssing the advantage of water on the intercooler during my remap I thought I would give it a go, and show you guy's how I got on.

I read several other posts where either a seperate tank or the exisiting tank was used and the headlamp washer pump/circuit was used. But thought I could come up with something a little more 'factory fit'.

My solution :

Pump / Washer Bottle

I was going to go the seperate bottle / pump route until I spotted that the standard washer bottle pump had a little surprise in store.

Now I'm not sure if all Impreza/WRX are like this, but on my MY00 UK there was what appeared to be a spare location on the front of the washer bottle for a 3rd pump just to the right of the standard pump. The MY00 is fitted with 1 pump in the base of the washer bottle for headlights and 1 pump in the front of the washer bottle just behind the battery, for winderscreen.

Further investigation found that it was identicle to the standard pump location, all be it missing a hole for the pump to be inserted. It's even moulded to hold/clip the pump securley into place.

A trip down to Halfords and a suitable pump was obtained for £14.99, this being similar to the standard pump i.e about a 20mm 90 degree inlet for the washer bottle and 3/16 outlet for the washer hose. Note : This is not the universal one that the halfords catalogue, incorrectly advises for a Subaru Impreza.

A hole was then drilled into the washer bottle using a 22mm wood boring drill bit. A spare piece of rubber hose was then pushed onto the pump (very tight) and then the pump wedged into the newly drilled hole. A small amount of sealant (the same stuff I used to seal my tail-lights) was used to ensure a leak free finish.

Job done and looks factory fit, see below



Washer Jets
Hozelock micro-irrigation jets seemed to be the order of the day. Unfortunatley I could not locate any in my local B&Q and Garden Centre. However, I did source some similar items from the 'Gardena' range. These are also micro-irrigation and are a 360 degree misting nozzle.
Bargain price of £3.89 for 5. Not £9+VAT each as per the STi items.

These were fitted by piercing the rubber gaiter on the intercooler seal with a 3mm drill bit. The nozzles where then carefully pushed through on the left and right hand ends of the intercooler. They where then held in place by connecting the 3/16 washer hose (£2.49 from Halfords for 2.5 meters). This had to be warmed in boiling water before attaching to the nozzles.

A few carefully placed cable ties ensured that the nozzles are held firm and pointing the general direction required, see below




Manual / Auto Operation
The pump was grounded with a short length of wire via the washer bottle mounting point. The power feed to the pump was run into the car for connection to the switches / relays.

For Manual operation it is just connected to a standard automotive relay (£4.49 from Halfords) and switch arrangement. The switch providing the +12V to enrgise the relay coil, with and 2nd 12V source driving the pump.
Flicking this switch drives the pump until you flick it off again.

For Auto operation, the connection is as per the Manual, but using a vacum pressure switch (Ebay £16.99) between the On/OFF switch and a 2nd automotive relay arrangement.
Flicking this switch causes the pump to run when the pre-determined pressure level is reached. The particular pressure switch used can be set to switch between 4 & 15 psi.

At present I have 2 temporary switches poking out of the dash adjacent to the steering column (see below), until I can source/justfy splashing out for pukka subaru items.



Total Cost :

Pump £14.99
Relay £4.49 (2 required)
Washer Hose £2.49
Nozzles £3.89
Wire £2.49
Washer T-Piece £1.49 (2 required)
Pressure Switch £16.99

Sundries : Crimps, Switch x 2

cheers, might give it a go, might help as I have the mk1 slanted intercooler and it doesn't appear as efficient as it could be

[Davey]

I'll post up some pics of my creation and some photos when I'm done

[Davey]

Nearly there, got the late spec STi intercooler spray bottle and air feed installed



Fills out the engine bay nicely!

Thats a nicely thought out install.

You could also use one of the unused warning light holes in your dash as a 'pump live' indicator, Either using the dash wiring or a small bulb holder.

[Davey]

There is an IC spray light on the dash somewhere which I think we'll wire up the level indicator too, going to source a pressure switch for the pump and there is a aviation type kill switch on the way to go in the dash.

Miltski

I think he means they cost HIM £20 when he bought them. So he is selling for £5 saving to someone.

Davey,
It looks like you can get switches off ebay, or you could get an adjustable overboost cutout switch from a 5GTT http://www.rtoc.org/home.asp.

One you tune these cars people throw them away and aftermarket samco boost hoses etc do not have the fittings bult in. They are 1/8 BSP but fit down the end of a t'd off actuator pipe nicely.
Expect to pay around a fiver.

miltski

sorry i was being dumb!

Yes mate, £15 inc postage to anyone who wants them.

I paid £20 when I bought them with postage on top.

PM me if you want them.

I've piped it all up now and tested the system, the spray nozzles have too much of an angle on them so most of the spray hits the top of the vent and the back of the I/C, will have to experiment with some different nozzles or fit some kind of restriction to lower the pressure.

iTrader: (2)

you can get some nozzles that spray a mist, i am guessing that these maybe better

http://cgi.ebay.co.uk/Aztec-Garden-I...QQcmdZViewItem

these people do them i think

I too have an MY99 you can see on the above pics that there is 2 flats on the shroud for the scoop, i will be putting mine in here as it's the std place for the Sti ones, will also be running them off the headlight washer pump/switch/bottle as it's already there and i almost never use it

scoobykevuk

exactly what i did using the same nozzles,works a treat.

[Davey]

They are the ones I've bought and they are pretty rubbish, the plastic has a very low heat tollerence I dont foresee it lasting very long..
