It's lightweight, relatively inexpensive, easy to machine, weld,
extrude, and form, and an especially good heat conductor, Josh.

Because weight savings are a good thing. The lighter your vehicle the
less energy needed to move it, whether on flat roads, or stuck in
(guffaw) deep mud!

Why, yes, Joshua, it certainly is. Its thermal conductivity is rather
efficient. More so than steel. Do you have a piece of aluminum stock and
a sander? Sand the aluminum and grind a hell of a lot of material off.
Gets kind of hot in your hand, doesn't it?

Re: Aluminum Radiator
 

Joshua,

I guess I should quantify that. I don't have a computer controlled engine,
so it isn't important that my coolant temp is in that range for emission
control. Running an engine at 210 if you don't need to isn't wise, as the
excessive heat plays a role in a number of possible mechanical failures such
as belts, hoses, major engine gaskets and seals. In other words, it is best
if you can run the engine as cool as possible, without going too low, which
creates problems as well.

A cooling system that allows an engine to run in that range doesn't exactly
have a direct effect on the above mentioned (possible) problems (except for
maybe head gaskets), but the under hood temps that it creates does. This is
why 210 makes me nervous.

Re: Aluminum Radiator
 

True, but that is assuming that you are moving at a speed above a crawl. I
come from the drag race and sprint car world where any temp that starts with
a 2 is bad news. But, with the advent of computer controlled engines and
emission laws, temp ranges in the low 2s are normal. The good news there is
without a PCM controlling these engines, 210 would be certain death for
them. 210 degrees, 10:1 compression ratio and 87 octane gas? Pretty cool
actually. Without the PCM, that is a recipie for a roadside picnic.

Re: Aluminum Radiator
 

well - I have been trying to find out the coolant temp required for closed
loop mode. I looked in the FSM & it only says "operating temperature" I
tried Google.......& I found that the O2 sensor has to be 600F on a Toyota,
but I do not see a specific coolant temp anywhere.
If you run a cooler T-Stat, it may cause the JTEC to switch, back & forth,
between open & closed loop.
