Over heating -- followup and question

[David Brady]

They paint them black for the same reason that disc brake
calipers are painted black - heat radiation. Everything radiates
heat in the form of electromagnetic waves (energy). The ideal
is Black Body Radiation. The emissivity of a painted black
object radiates more like an ideal Black Body than other painted
colors.

David:
Thanks, seems reasonable. After Pete posted his problem I checked mine out
even though I do not have overtemp problems. The last time I cleaned my the
radiator was 18,000 miles ago. I washed it out this weekend and was amazed at
how much black water came out of the oil cooler, condenser and radiator. The
bus gets dirty with road film from the rain and all of that crud is sucked into
the radiator by the fan. I will repaint my radiator black next weekend. The
condenser and oil cooler are not painted?? Any ideas on that???

Leroy I too cleaned my radiator recently and did the best I could without
taking the thing out. I noticed some paint had flaked off but opted not to
repaint because even though I cleaned it out as best I could I am not
confident that it is clean enough to paint. I'd be worried the paint would
combine with any dirt/soap residue left behind and clog the fins up.

Hi Leroy, there's no doubt that the condenser and oil
cooler would radiate heat better if they were black, but
I probably wouldn't paint them black for a couple of
reasons: 1) they are probably performing their job
adequately the way they are, and 2) they look stock and
original the way they are. Maybe the manufacturers didn't
paint them because they didn't want to spend the
money on paint, or maybe manufacturing was quicker
without paint, or maybe painting ran the risk of closing
off important air passage ways. In any case, I'd leave these
items in their stock condition. Just my humble opinion.

Douche that bad boy with Brake Kleen, not the safe stuff, the evil old fashoned
kind that really works. A case should do the trick and it WILL clean out any
thing.

Leroy,
Did you remove the condenser and oil cooler before cleaning the radiator?

Rob; I follow you. I used Simple Green and a pressure washer. Most of the
paint is gone on the outside fins. It's a beautiful bright copper color. I
worry about corrosion in our area. I appreciate your input and will give it
some thought.

Mike-- that is the cleaner that has acetone, MEK and other goodies in a spray
can available at WalMart or NAPA right?
Just do no not get it on the paint.

What you see when you open the "grill" is the "charge air cooler". It
is aluminum and is silver in color. It is _not_ the water radiator.
Do not paint it. The water radiator is behind the charge air cooler
(and not visible from the street side). You can see the water
radiator from the inside. It should be black in color if you can see
any of the original paint under the grime that coats everything in
the engine compartment. If you have chassis air conditioning, the AC
condenser will cover the bottom 1/3 (or so) of the water radiator.
AC condensers are also (usually) made of aluminum and are not
painted. The water radiator is often made of copper or copper alloy
and is painted to protect it from corrosion. Aluminum is often left
unpainted as many aluminum alloys are 'naturally' protected. (Looking
at 2 automobiles, 2 wall AC units in my house, and 3 AC units on the
top of my 'bird, none of them have the aluminum condensers painted.
There must be a reason that probably does not have anything to do
with "black body emission.")
