Over heating -- followup and question - Leroy Eckert - 09-10-2006 13:31
Curt:
No, I was able to get around behind both of them as well as through them. I
also was able to get in between the fan blades and behind the shroud. I was
pretty wet when done. My condenser and cooler cover about 40% of the radiator
surface area. I think I got 90% of it. After dark this weekend I will check
with a light. If necessary, I'll fabricate a flexible hose for my pressure
washer to get the rest. Just need to pay attention so it doesn't beat up me or
the equipment

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

Over heating -- followup and question - Mike Hohnstein - 09-10-2006 13:34
Yeah? Why's that? You know something I've missed?
I suggested BRAKE KLEEN, not carb cleaner. That stuff might even get the
urathane to lift.

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.

Over heating -- followup and question - Leroy Eckert - 09-10-2006 14:33
Pete: I am not going to paint anything that was not painted prior to cleaning.
Don't want to screw up. I can see and feel the water radiator(copper in color,
previously painted black) on my coach from street side as well as the fan side.
The fan side is more difficult. In front of the water radiator street side is
the a/c condenser on top and below some kind of oil cooler. It's tight but I
can place my hand between both of these units and the water radiator street
side. Both units are aluminum. Perhaps it is a charge air cooler. I was going
to trace the lines on that unit today but was unable to do so because unfriendly
fire ants were in the area. Is the charge air cooler associated with chassis
air? I'm not familiar with the term. Thanks for the help.

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.")

Over heating -- followup and question - Pete Masterson - 09-10-2006 14:51
Leroy,
Sorry ... I forgot for a moment that you have the 8V92 and the Series
60 in my 'bird is set up somewhat differently.
If the copper radiator is visible, repainting it might be a good idea
as it would protect it from corrosion common to copper (although in
some applications, copper will form its own protective 'green'
coating) -- but the verdigris (green coating) might also tend to clog
in a radiator and/or may interfere with the heat transmission to the
air flow (while it isn't a problem on (say) a copper roof).
On the Series 60, the "charge air radiator" cools the pressurized air
from the turbo charger before it goes into the engine. (At least
that's what it looks like in the DD engine manual I purchased.) An
8V92 may not normally have a charge air radiator.
In my coach, the transmission radiator is separate from the main
radiator and is unpainted aluminum. The chassis AC condenser is on
the _inside_ of the radiator and is also made of aluminum.
So, your '90 WB-40 is set up very differently from my '95 with the
Series 60 and therefore the "lessons learned" from my radiator
experience is only indirectly applicable to yours -- (e.g. cleaning
the radiator is a really good idea, but the specifics of the set up
are quite different.)
I didn't mean to cause confusion ... and I should have taken note of
the differing engines and likely differences in the layout. My
apologies.

I doubt you will find any in CA. My shop gets it in 55 gallon drums, I scream
at my guys not to get it on their skin. We supply them blue leotard gloves for
protection, like Doc puts on before he fondles yer prostate.

Over heating -- followup and question - Gregory OConnor - 09-10-2006 17:42
Curt, They sell it just south of SanDiego. Just dont overlook the
great job hotwater and laundry detergent does. You can get sodium
phosphate in a plastic bag "Arial" at Stater Brothers. I soak gunky
oil with diesel fuel (diesel is thin oil). this softens the gunk
then wash the diesel off with hot water and laundry soap.

Over heating -- followup and question - David Brady - 09-11-2006 02:30
Pete,
The net heat power radiated is the difference between the power
absorbed and the power emitted and is proportional to the
difference in temperature between the surface temperature of
the radiator and the surrounding ambient air temp. This delta
is high for the engine radiator and low for the charge air cooler
or for the ac condenser. In other words some items are left
aluminum because if they were painted they could potentially absorb
more heat from the ambient air then they emit. The engine radiator
benefits from being black. Black cars' interiors heat up faster than
other colors, at night time, they cool down faster; i.e, they absorb
heat better and they emit heat better than white cars. It's physics.
