[Tigers] Cooling etc.

Yup, black  body radiation effects. Plus if you  can find a high “e” paint to use, even better. But,  basis black is always a good place to start.

I did a test where I tried reading the temperature of the copper pipe that carries hot water to the baseboards in my house, with my IR thermometers.  With the circulator running I made two measurements, one on a nice clean spot on the pipe, and another, about an inch away, on a section I painted black.  Surprise.  Different numbers, with the black reading being higher.

 

IIRC the instruction manual for both of my IR gages say that best results are obtained from black surfaces.  So if you plan to get good readings off that chrome thermostat housing or your nice shiny F4B, think again.

Regarding the link, Not trying to make this into Angies List but the word of mouth I have gotten and the replies or lack of them suggests they have a nice website but little inventory and can't spell customer service.  I have also heard that they don't have some of the items they picture and that they said they will not be making more.
So I guess this falls into they can pay a web developer to make a really nice site, but  don't bother to update it. Sorry for the thread detour, I like to buy and repair bashed expansion tanks but it's very time consuming. 

But now back to the cooling topic. I converted my car back to using a expansion tank, "had Dale's 1999 Davis radiator," and as with all things cooling every change adds a bit more ease to temp mgmt. I also did the don't trust the stock gauge with a P.O. selected off the shelf temp sender.  100% important to verify temp with I/R and add resistors in line to gauge so its correct in the sweet spot of 180 to 190 ish.
