water to air IC polishing

[Guest]

just wondering if it is ok to strip the black coating around the waic for polishing??.....does the black paint stop it from heating?

[BC5RA]

It'll be fine, the black coating is just paint.

Maybe pick yourself up a silver cooler and start from there.

got this from teh intraweb:

A car painted black absorbs from all the colours in the sunlight and so its electrons take in much more of the light's energy to move themselves to higher energy levels than a car painted white which reflects the light. We can feel these higher energy levels, black cars feel hotter to us.

Administator's note:

This is a good description of what happens when a white and black object are both in the sun, but the reverse will be true at night. Black objects generally radiate away energy faster than white ones, so they cool faster. Notice that heat sinks on electronic compoments are generally painted or treated black.

So, your i/c inside your bonnet will actually dispell heat better if it is black?????

In conclusion, subaru knew wtf they were doing

[DRFVDR]

90 0n is my guess

my '90 GT had/has a silver one

[DRFVDR]

[sickmatesick]

[DRFVDR]

oh then I have no idea

[Swindog]

The diffrence will be negliable mate, do what takes your fancy

[BC5RA]

The Factor Denso water level indicator was found on the Silver intercooler tank.

The silvercooler was fitted to 89-early 91 series 1 Legacy, Black intercooler 91-End of production.

Gold cooler was actually a coating called Alumite and was fitted to Series 1 (Non facelift) RS type RA, this model shares Alumite gold cam covers throughout total production.

I've got a '92 with a black one. On the note of water-to-air coolers, is plain old water ok or should it be a mix of anti-freeze/boil like engine coolant?

[BC5RA]

Water alone will corrode over time.

You should run coolant plus water.

Or if your really fussy (like me) then fill with demineralised water and Redline water wetter.

Thought so, it's just very hard to read japanese if you've never read japanese before (yes, my car is an import).

ALL subarus are imported(yes some a sold new in New Zealand but still imported as a CBU)

And u will find that there is not many NZ new Legacy/impreza's on here

May try polishing my one

[G-unit]

yea polish it and show results,honestly cant see it heating much at all compared 2 the stock colour if any

[ReubenH]

I put my money on the mainly for looks argument

Why are radiators painted black? Why is a legacy intercooler painted black, and an STi one silver.

[G-unit]

also most aftermarket top mounts and front mounts are silver hehe paint it bright green

[Guest]

haha atleast youl get a response from some guy checking your engine out with abit of fluro in there....not sure what the response will be tho:S

[DRFVDR]

Have started to do this to my spare

at the mo it is having its paint stripped(CRC gasket stripper FTW)

may put pics up will see

[Guest keltik]

Tempted to do my intake with that 2 part metallic paint Glen tarted his engine up with. Would look bitchin'

89 GT had a silver cooler, 90 RS had a black one.

[DRFVDR]

WOW under the black paint is a very nice alloy pressing

will look nice polished

I want my car to remain a sleeper/stealth. Can I paint or anodize my intercooler so it is not easily visible?

Yes! It is not uncommon at all for an intercooler and endtanks to be anodized black to keep attention away from the car and help it maintain a sleeper appearance. A very light coat of paint on the core and endtanks is also another option, usually much cheaper and easier than anodizing, with a negligible performance loss.
