Question edited for clarity 'power STEALING!
Question moved to model category.

Unfortunately the power steering is full electronic. It does however appear to be a known issue. The club Lexus is always a great resource, I am a member with my ES330.

There really is not much difference in fluids. If you have been having issues I would suggest a bottle of Lucas power steering conditioner.

Yes
You may have to remove the power steering pump in order to get your hands down in the passenger side of the engine to remove it.
when reinstalling pump be careful not to let any power steering fluid drip down into alternator. That could cause a premature failure of the alternator.

if it is for the power steering system or the hydraulic cooling fan then you only need power steering fluid.

The main purpose on an alternator is to recharge current back to the battery. One of the most common problems with the Lexus LS400 and SC400 is that power steering pump seal leak. Right below the power steering pump is the alternator. The power steering fluid will drip down and cause many electrical problems for the alternator. Therefore, its very common to have the alternator go bad along with the power steering pump, just be sure to check.

xus LS 400 and locate the power steering pump pulley, fluid reservoir and pump on the upper front driver side of the engine.

2 Connect the pulley remove tool to the front of the power steering pulley. Brace the arms on the pulley tool on the **** of the pulley. Connect the metal key in the middle of the pulley tool to the nut in the middle of the pulley. Connect the power drill to the pulley tool and pull the trigger to remove the pulley securing nut. Remove the drive belt and the pulley.

3 Position the drain container under the power steering pump. Remove the drain plug from the bottom of the pump using the metric ratchet set. Let the fluid drain from the pump into the drain container. Replace the drain plug to the bottom of the power steering pump.

4 Remove the securing bolts from the right and left side of the reservoir and the pump using the metric ratchet set. Pull the pump upward and disconnect the hose from the bottom of the pump using the wrench. Pull the pump from the engine compartment.

5 Lower the new power steering pump into the engine compartment. Reconnect the hose to the bottom of the power steering pump. Position the new power steering pump onto the engine. Replace the securing bolts the right and left side of the pump and reservoir. Tighten the bolts using the metric ratchet set.

6 Replace the power steering pump pulley the opposite way that you removed it. Reconnect the drive belt.

Fill the power steering pump reservoir with fresh power steering fluid. Start the engine and rotate the steering wheel to circulate the new power steering fluid. I no i gave you directions on how to remove the whole power steering pump question is the pully loose or are you wanting to just change a belt good luck happy holidays

As mentioned check ps fluid. If it wines when turning and still no power then the pump is internally bad.. If the fluid is dissapearing fast then its a hose or most likely a leaking rack& pinion assembly..

it's fine to add any fluid to this model , its versatile, you can even use milk or tomato juice.

you're welcome

The leak could be in the steering rack.

There is a loud squeak on the front of my 1991 ls 400. The squeak is near the alternator. Any one no what it is?
