1996 LS400: Engine Fan spinning too freely ?
#16
Okay, I'll bite: What is the Fan Fluid Reservoir actually lubricating? And I'm curious; how you are going to get that silicone into the fan clutch? I have a '99, so I'm sure it's different, but I'm still curious.

the fan fluid reservoir was a weird system on the SC300 and SC400 that held ATF fluid which ran the fan via a hydraulic motor, pump, and a little mini radiator and associated piping. - the fluid is not for lubrication as much as it is acting as hydraulic fluid - it is similar in theory to your power steering system, but even more complex!
be very glad you have a sealed fan clutch rather than this expensive contraption!
he's not, our fan clutches are factory sealed and should be replaced as an entire unit when they lose their viscosity, and your 99 and his 96 use essentially identical fan clutches, which require no maintenance - if your A/C ever doesn't get cold enough, then it might be time for a new one!

I thought you had a 96 LS400?
LS400 doesn't have an Engine Fan Fluid reservoir, that is just the SC models, and any Lexus that has the fan fluid reservoir will NOT have and fan clutch and vice versa!
your fan clutch is a sealed unit, just because some bozo company sells silicone to put in it, doesn't mean you should! - if your fan clutch is spinning too freely, you need a new one, once we figure out what car you have, we can find you one online cheap!
now it is time to decide if you have a fan fluid reservoir or a fan clutch - pick one!

As for the silicone, I believe my fan clutch requires it due to spinning soo freely and even continues to spin when the vehicle is switched off, consequently will proceed to change the silicone in my fan clutch

if it was still a $300 part, then I might take the time.

I have a Fan Fluid Reservoir....The logo on my vehicle states SC400 as seen in the picture below...BUT....the authorized certified registration card for this vehicle states 1996 TOYOTA CELSIOR only.....Therefore, what led me to thinking its an LS400 ? Try going to Google, type in 1996 SC400 and see what comes up....Then again type in 1996 LS400....Dont you find my vehicle fits the image of an LS400 and not the images for the SC400 ?

still really strange to have the SC fan fluid craziness on an LS - but having a JDM is otherwise very COOL
PS - as I said earlier, but bears repeating, you do NOT have a fan clutch on this beast whatsoever, so do not get that silicone anywhere near this car, you will ruin it!
I would completely change the ATF fluid in your hydraulic fan system, but get a buddy who has flushed a power steering system before to help you - and never run the car with the fan fluid low, or any other fluid low, for that matter!

Thanks for your feedback PureDrifter. Now, unlike the vehicle in the above link, my 1996 Lexus Celsior only has ONE Fan, which is the Engine Fan. No electronic Fans to the front of the condensor etc. Here is a pic of my engine indicating no fans to the front. And the latter pic showing my Engine Fan.
Weird.

That is not a SC400. It is a JDM Toyota Celsior and it is natural that the fan spins freely by a hand when the engine is off because it has a hydro fan. Once the engine is started, the fan rotates sometimes slowly and sometimes fast depending on the heat generated by the engine.
We live in a small country but the summer heat and winter coldness are something special. We also have traffic jams very often. To meet those conditions, Toyota must have decided to use a hydro fan for a JDM.
