I'll chance my 'fan bracket' to the stressors it was engineered for -- I don't need my engine bay running any cooler than it already does. My LS already cools a bit too much as it currently stands,.. Running the engine temp an lower than it warms to would be more harmful than good. (In my scenario).
You've really got to do some altering of pulley drag to get any signficant HP from it. Removing the fan might give you 2-4hp,.. No one can feel 5hp,.. you just can't. Now mess with the alt. pulley, remove AC compressor, or change pulley.. (basically do them all to some degree) and you might gain 10hp. At the cost of charging issues, and waterpump working slower and so forth. Better ways to get horsepower than pulleys.
But if anything, yes, swapping in adequate electrical fans would be the most sensible alteration to Serp. belt , drive pulley drag. -- You say your engine bay runs alot cooler? What does this translate to? Significantly lower engine temperature? It feels nice when you open your hood for a nice breeze?

Engine bay gets nice and warm, and then rubber things start to go south very fast.
Can I feel a difference in engine performance with this mod? Oh yes, in this damn car, any hp increase is noticeable...
I'm sure skperformance, Lextreme, and choice others agree with me on these points...

I can see where you're coming from, but when my fan clutch start to wobble, I opted to run the electric fan conversion. Am I saying it is better than what Toyota designed it for now? Yes, to a point. They opted for the fan due to noise. I opt for better cooling.

You know, I have a reason to suspect that the water pump I put in, as well as the timing belt and tensioner, are not for a 1994 LS, but for a 1995-1997. See, when I ordered these parts from a Lexus dealer, I also bought a set of brake pad, and specified that all these parts were for a 1994 LS. However, the brake pads turned out to be for a 1995-1997, so I ended up sending them back. It just occured to me, what if the rest of the parts were for a 1995-1997 as well? They should be pretty much identical, but I read somewhere that a 1st gen LS400 water pump had six fins, while the 2nd gen has 12 fins. Obviously, theres no way for me to determine how many fins this pump has without removing it, and I lost all my order receipts. But if it is indeed a 2nd gen pump, and I'm actually getting more efficient cooling, it may not be such a bad thing after all.

jesus dude, i skimmed over the thread so apologies if i missed it... but have you seriously not just taken the 5 minutes out of your day to pull the thermostat housing off and look at the stat? its a $12 part and it takes a pair of pliers and either a 10 or 12mm wrench to remove, you will spill maybe 3 ounces of coolant....

I replaced the thermostat, and its still doing the same thing. I believe I stated that in one of my posts.

My 95 that I just purchased a few weeks ago would not go past the first line on the coolant gauge but I noticed today that it was up close to the 2nd line which would put it in the cool end of the normal range.This car was not driven more than 350 miles the past 3 years so I think the Tstat was frozen a little.I also noticed the gauge sticks sometimes along with the tach and speedo.A slight rap to the dash seems to unfreeze it
