I have been thinking about the possibility of making my own DIY I/C spray kit for MY00UKTurbo.

At present I have the rather useless Headlight washers. Now if I were to disconnet the washers to the headlamps and redirect the pipework back to the intercooler - buy some STI nozzles for the underside of the scoop, then surely this would act in the same way a i/c water spray would ?? Agreed you would have to use the headlamp washer button inside the car, but this would be a very cost effective way of producing an i/c water spray which could at anytime be reverted back to its original state.

Has anyone done this mod or any ideas as to whether it would be feesable ?

great idea it should work fine you can still leave one nozzle for your windscreen and one can be used for the intercooler, wind screen wash fluid should be fine to cool the intercooler

I haven't looked yet but would anyone know whether it is an easy job to get to the pipework that controls the head light washers ?? I assume its going to be a Bumper off job ?

oops sorry just read what you wrote headlamp washer! not windscreen washer try using the windscreen washer!

Im doing just this, Ive ripped out the pump, pipe work, nozzles and switch out of my 94 legacy and am trying out a 18 liter tank in the boot.

The switch is the h/lamp wash switch which will fit nicely where the IC switch would go. This is untill the actuall switch turns up.

Im using three head lamp washers which i will locate on top of my FMIC facing down or on the spliter facing up. I will posts pics of my progress tomorow.

Headlamp washers aren't really the thing to use Aston, they produce a fan/jet, whereas what you really want is a fairly diffuse mist.

You can get STi spray jets as spare parts from Subaru dealers as well as most of the specialist/breaker type people. In the circumstances it'd be worth getting hold of a couple of the right ones as it does make a difference. Washer jets will likely shoot most of the water straight to the back of the I/C, whereas what you really want is fine droplets hitting its entire surface area (or as much of it as possible).

Yep done it on my UK MY98 a couple of years back

Some things may be a little different due to the age difference of the cars.

What you need to do

1. Remove 2 x screws holding in water bottle
2. carefully lift up bottle and remove 2 x connectors to motors
3. Remove 2 x water pipes from motors (watch your feet don’t get wet )
4. Now you have access to the pipes.
5. Follow the larger of the 2 pipes (headlight washers) towards the front of the car. You will feel a solid part where there is a join. Separate pipes here by pulling apart.
6. You will req a reducer pipe from the headlight washer pipe to normal windscreen washer pipe.
7. Reconnect the wires, pipes and bottle back into position. When you connect the now intercooler pipe redirect it to the rear of the car.
8. Connect normal windscreen washer pipe from reducer and direct to intercooler. Run along same path as windscreen washer pipes.
9. Use 1 x ‘T’ piece to separate water supply to the flats in the intercooler under tray where the 2 x Sti nozzles will be placed.
10. Remove the intercooler under tray and fit 2 x Sti spray nozzles in the flats. (use drill and then file to make it square) Sti nozzles available from places such as GGR or search Google for a supplier (about £20 for a pair)
11. Refit under tray and connect hoses.
12. IMPORTANT ! use tie wraps on every join or you will spring a leak.


PIC !


I would suggest you refill the water bottle with just water just to be on the safe side.

You could also get yourself a Digital temp gauge from this guy

mike@rjpipe.demon.co.uk

They are about £40 but fit nicely in the car. Once connected to the intercooler it will let you know when your charge temps are high and thus when best to use the manual spray.

Any questions just drop me a PM.

Nice one Neal - thats exactly the sort of instructions I was hoping for

NM

I aim to please

Cheers GM i will take your advise.

wrxtankie

mine will require three jets as i am running an APS DR500, which has a larger than normal frontal area.

I will post up pics and info on my progress, If you can call it that
