6x6 Heater Core Shrouds

[Lothar5150]

I'm not a vendor-just a fellow OCer. It is designed to fit all of the common 6x6 heater cores (CHEVETTE, FIERO, FESTIVA etc.)

Take a look:




The shroud in these pictures is painted grey in order to get better detail in the photographs-the production color is black.

If you have any questions:

you will not have dissimilar metals creating corrosion problems in your cooling system.

I personally don't have water flowing through the fan shroud on my radiator, but whatever floats your boat.

I generally don't push water through my fan shroud ether. However unless you live in a dry climate, galvonic corrosion can still be a problem.

Generally properly functioning aircraft don't go into the water but galvonic corrosion is a problem due to the number of dissimilar metals used in there construction. Typically this is the worst type of corrosion because it can only be detected by disassembly and inspection or finding it after a failure (Ref DOT FAA AC65-9A)

This is all you need for galvonic corrosion to occur:

First there must be two electrochemically dissimilar metals present. Second, there must be an electrically conductive path between the two metals. And third, there must be a conductive path for the metal ions to move from the more anodic metal to the more cathodic metal.

By that logic alpha, swiftech, and many other heatsinks would also just spontaneously corrode in air? I am familiar with galvanic corrosion in marine environments, but I have to admit I am not at all familiar with such corrosion in air. My instincts would be that it is usually only a problem with metals that sit out in the rain, and that it would take many years. I am sure you are also aware that the rate of galvanic corrosion depends upon the difference in potential between metals. Do airplanes use a lot of copper? Aluminum I could see, but copper no. I think you may be being a bit liberal with the facts...

I am assuming you are talking about the DTek shroud? The one that I got from them wasn't made of aluminum, and it had some weatherstripping on it to isolate it from the heatercore itself. I found it to be of very high quality, with no gaps at all. It is also a good bit cheaper than $25.

I don't know about Alphas but Swiftec Anodizes all their aluminum parts. This helps prevent galvonic corrosion. Aircraft don’t use a lot of copper. Mostly Steel, Magnesium, Titanium Zinc and Aluminum take a look at the potentials between metals for yourself-that’s why I added the link.

I didn't mention the name of the manufacture and I will not but when I post the pictures of my shroud tonight- I'll post a picture of the shroud that I got from _____. Then you can compare the two and decide for yourself.

I don't know about you but I'm tired of ordering water cooling supplies and having them show up looking like someone’s little brother made it. $25 may seem a little high but it is a professionally designed and manufactured product. This is not something out of little Johnny's workshop.

Swiftech's heatsinks were what I was referring to; not sure if the new helicoid pins are anodized but some of the earlier ones weren't. Alphas are anodized black, but not the part where the copper and aluminum touch (the anodizing is done post-production).

Your shrouds look very nice, but I personally believe there is more than a little FUD in your comments about corrosion inside a computer case (airplanes are faced with a greatly different environment than the PC, and aluminum exposed to air will usually form al-oxides that are resistant to corrosion anyway).

I've seen those before, at home depot or the hardware store, can't remember. in the dryer duct section.

No there designed specifically for a 6X6 heater core.

I dunno, I am impressed!

Nice work!

The Dissimilar metals thing is a bit of a funny line, but what the hell? The world runs on FUD now anyways

Thanks Joe

errrr ive seen them in the hardware stores and all over. unnamed vendor must be fleet farm menardes ace hardware home depot etc. they are only like 3 bucks to.

Home Depot Humm I am going there to pick up a new BBQ I'll have to take a look. If you find one at home Depot you sould post a picture
