Engine efficiency my ass.Interesting, I have never heard of that. I would guess the reason for it would be engine efficiency, if you have one less belt driven piece on the engine, it would be slightly more efficient. I'd think if you could control the flow of fluid just right it would be a nice setup, but I'd hate to clean up after a major leak, just imagine losing a line and having the fan blow ATF all over the engine bay.
People forget that the power to rotate that fan must come from SOMEWHERE.
"Conservation of energy"
And to move X-volume of Air is going to require Y-Volume of force
and this doesn't change.
It doesn't matter a mouse turd's worth of difference if the power comes
1)mechanically driven by the engine belt bolted to a mechanical fan on the
BELT DRIVEN water pulley
2)Electrically off the electrical system by the BELT DRIVEN
alternator(Hey STUPID PEOPLE, The engine must STILL drive the alternator)
OR
3) driven by the power steering system which is owered by the Power steering
pump which in turn is turn BELT DRIVEN
alll of these BELT DRIVEN things ARE powered by
the ENGINE, so where is this magical power comming from? the gasoline that
you pour into the tank.
And if people are puzzled why I'm disturbed ponder this...
How is the HYDRAULIC motor driven fan controlled for necissary speed/airflow?
How does the hydraulic system "know" how fast to make the fan run?
Can you say complication on top of complication?
In my engineering mind "complication" is "Bad" and "Simple" is "good"
NECISSARY complication often cannot be avoided, but why engage in UNnecessary complication.
I'm disturbed by the foolish absurdity of this complication.
I'm more than a little inclined to buy that fan assembly to hang it on my wall
as a monument to "what were they thinking?"
You cannot tell me that this hydraulic motor is cheaper to produce or easier to
control than an electric motor... and if you try I'll make it a point to beat you.
No, not beat you senseless that would be redundant... just beat you to liberate
my repressed rage at stupidity in general.
Ok so let me get this straight... you say that to replace the plastic fan that cracks (but doesn''t actually break)hydraulic motors last many years. probably puts very little more load on steering pump, less than a belt driven fan. my guess is to replace the fan that ALWAYS breaks between the blades, and lasts way longer than an electric motor that gets water FORCED into it when its raining
they design ANOTHER plastic fan, a plastic mount like an electric fan, a cast aluminum Hydraulic motor that
has THREE lines running to it, the lines, some sort of control valve and some complicated electronics to operate
the control valve and to you this is an improvement?
Alrighty then....
