Differences between "coolant" and "antifreeze"

[silver eclipse]

Water + Antifreeze = Coolant
There is no better heat displacer than water, The more psi placed on a system the hotter the water must get to boil or "over heat". For every psi water is pressurrized the boiling point increases by 3F
Antifreeze is an antifreeze, Anti corrsive, and a lubricant for the water pump.

68% water and 32% antifreeze is the ideal mixture in all scenarios. Where its colder out side 50/50 maybe be wanted to prevent freezing, In florids 70/30 is just fine as well as 50/50. 50/50 obviously is easy enough to hit.

Just thought I would throw that in there. Even thought its not what was originally asked.

Not true...

Coolant is coolant. Antifreeze is a type of coolant.

Antifreeze/coolant is made to both extend the liquid phase of water (below freezing and above boiling) and improve its specific heat capacity.

Way off topic, I will probly get in trouble for carring this on, so sorry

Coolant is a mixture of antifreeze and water. That is true, Just for giggles I checked in my Modern Automotive Technologies book that ive used in auto tech for the past 4 yrs. I knew I was right, but wanted to make sure.

That is absolutely wrong.

Coolant is any fluid (liquid or gas) with a high heat capacity used for transferring thermal energy away from the source. Antifreeze is a particular type of coolant used in automobiles to alter several properties of water to suit the application.

Antifreeze mixed with water is antifreeze mixed with water.

I believe you misunderstood what they're saying in your book, sir.

Im sorry, I believe your misunderstanding me. Im refering to automobiles, not anything else.

Gas does not have a very good cooling efficiency, with out compressing it into a liguid, unless your using it to purely spray onto something. Most gasses that are used in a system to cool things is reffered to as refrigerent ex: A/C, Refrigerators

There are different kinds of antifreeze, Ex Green antifreeze, Dex-a-cool etc

Trust me, I understand the context.

Certain gases do have a respectable heat capacity (i.e. air; as in air-cooled engines?). Gases that are merely used to cool something are not all refrigerants. Refrigerants are kept in closed, cyclic systems, and always undergo a phase change during their cycle.

And there are different types of antifreeze, as you said... but that has nothing to do with the argument. In fact, you're just reinforcing my point, which is: coolant is any working fluid that transfers heat from a source; whereas antifreeze is a particular type of liquid coolant made from ethylene glycol, propylene glycol or OAT for use in automobiles.

Modern automotive coolant is a mixture of antifreeze and water, in the olden days they used to use alcohol mixed with water so yes antifreeze+water is a form of a coolant.

+1
100% water is a coolant.
Anything that lowers the freezing point of water is considered an antifreeze.

While water and antifreeze (which is inherently composed of some water) is a form of coolant, not all coolant is a water/antifreeze mixture... that was my point.

 

[silver eclipse]

I think some where we got off my original post, wich was discussing Engine coolant.
Engine coolant is mixture of antifreezer (what ever kind of antifreeze/Dex-a-cool) and water.
-Chad

I guess I was assuming Engine Coolant in my original post. Air does cool an air cooled engine, but it is not a coolant.

 

[VelocitàPaola]

I realize I'm arguing semantics here... but, air is a coolant.

Coolant is any working fluid that transfers heat from a source.

Air, while not a liquid, is a fluid.

 

[Defiant]

It is semantics. It's also largely a distinction without a difference. If you ask the parts drone for either antifreeze or coolant, you're going to walk out with the same product.

Unless he tries to sell you Dex-Cool, at which point he must be murdered. Slowly. Only so others will learn.

I second that notion.

We can continue this discussion for ever. So the thread is basically in my beliefs going no where, especially if we jump from engine coolants to all sorts of other coolants.
