Over heating -- followup and question
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 Eckert 1990 WB-40 Niceville, FL ----- Original Message ----- From: Curt Sprenger To: WanderlodgeForum@yahoogroups.com Sent: Sunday, September 10, 2006 7:51 PM Subject: Re: [WanderlodgeForum] Over heating -- followup and question Leroy, Did you remove the condenser and oil cooler before cleaning the radiator?

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.

Over heating -- followup and question
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. Leroy Eckert 1990 WB-40 Niceville, FL ----- Original Message ----- From: Pete Masterson To: WanderlodgeForum@yahoogroups.com Sent: Sunday, September 10, 2006 8:24 PM Subject: Re: [WanderlodgeForum] Over heating -- followup and question 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.") Pete Masterson aeonix1@...

Over heating -- followup and question
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. Pete Masterson aeonix1@...

Over heating -- followup and question
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
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.
