Re: Aluminum Radiator
OK, I seem to be confused between 190 and 195... use whatever the owners
manual says you should. You can't go wrong following the owners manual (I
hope).

I'll be darned, you're right, woulda thought brass would be higher
in thermal conductivity. However radiators are usually copper,
which is almost as good as silver, not brass.
Diamond 1.28
Silver 0.968
Copper 0.928
Aluminum 0.520
Brass 0.338
Obviously, what you need for your winch/jeep is a diamond radiator.

Re: Aluminum Radiator
I 'think' it is a 195 in most places, Bill commented something about
210's needed in CA for the smog police...
Just figure the hotter the t-stat, the more heat inside in the winter.
:-)
5 or 10 deg make a 'big' difference at -30 or -40.... Even - anything.
Up in the Great White North.

LOL!
So that is the second time you have mentioned copper rads???!!!
I don't believe I have ever seen a copper rad. All the ones I have
repaired were brass or maybe bronze (brass and copper) but I sure can't
think of any copper colored ones.

LOL!
So that is the second time you have mentioned copper rads???!!!
I don't believe I have ever seen a copper rad. All the ones I have
repaired were brass or maybe bronze (brass and copper) but I sure can't
think of any copper colored ones.

I used to see a lot of brass caps with brass tubes and copper fins but
I don't think I've ever seen copper tubes, much less end caps and I
haven't paid much attention lately but the las brass/brass radiator I
repaired had brazed foil to the tubes,
