Where is the power steering reservoir? - 2008 Lexus IS 250

However, typically, you can find the power steering reservoir under the hood, near the engine. It is often a small plastic or metal container with a cap labeled "Power Steering" or with a steering wheel icon.

Not all power steering systems are hydraulic. I think some G6 models have electronic power steering so no fluid is needed. Referring to the owners manual it appears that only the 3.9L uses a hydraulic system. If there is a reservoir it will either be tucked behind the alternator or mounted on that end of the engine. The top mounted reservoir filler cap is on top of the engine to the left of the oil filler cap.

Removal Procedure

1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement .
2. Remove as much power steering fluid from the remote power steering fluid reservoir as possible.
3. Place drain pans under the vehicle as needed.

6. Remove the power steering fluid reservoir outlet hose from the vehicle.

Installation Procedure

Hope this helps a little.

CAUTION: If the air is not purged from the power steering system correctly, premature power steering pump failure can result. The condition can occur on pre-delivery vehicles with evidence of aerated fluid or on vehicles that have had steering component repairs.

1. NOTE: A whine heard from the power steering pump can be caused by air in the system. The power steering purge procedure must be carried out prior to any component repair for which power steering noise complaints are accompanied by evidence of aerated fluid. Remove the power steering fluid reservoir cap. Check the fluid.

1. Raise the front wheels off the floor. For additional information, refer to Section 100-02 .

1. Tightly insert the stopper of the vacuum pump into the reservoir.

1. Start the engine.

1. Install the vacuum pump, apply vacuum and maintain maximum vacuum of 68-85 kPa (20-25 in-Hg).

1. CAUTION: Do not hold the steering wheel against the stops for more than 3 to 5 seconds at a time. Damage to the power steering pump can occur. Cycle the steering wheel fully from stop to stop 10 times.

1. Stop the engine.

1. Release the vacuum and remove the vacuum pump.

1. CAUTION: Do not overfill the reservoir. Fill the reservoir and install the reservoir cap.

1. Visually inspect the power steering system for leaks.

Locating the Power Steering reservoir and adding PS fluid. 1999 Pontiac GP

The reservoir is clearly visible in the engine bay on the 3.1 litre engine cars.

For the 3.8 Ltr engine cars, use a flashlight to look down past the alternator for a black cap with a steering wheel printed on it to indicate the power steering fluid reservoir. ( passenger side of the vehicle).

Remove the cap of the power steering reservoir, clean the dipstick, re-insert and remove again to check the fluid level. If the level is at or below the low level mark, add fluid slowly, taking care not to fill above the MAXIMUM mark. It's best to add small amounts and re-check the level as you go to ensure you do not overfill the reservoir above the MAX level.

ONLY use the power steering fluid recommended for that vehicle by GM.

You really can't flush out the steering system fluid other then siphoning the fluid out of the steering pump reservoir. This is the easy way.
The hard way:
Remove the filler cap from the top of your power steering system then disconnect the reservoir's hose. It should be located on the bottom of the reservoir. The hose can be tough to remove, so make sure you have plenty of patience.

Replace the reservoir's hose with another hose. It should lead to an empty container. You'll use this container to store the old power steering fluid as it leaves the reservoir. Lift the front end of your car off the ground by using a car jack.

Add new power steering fluid to the reservoir. As you add the new lubricant, it will force the old lubricant into the tube you've connected to the bottom of the reservoir.

Climb into the drivers seat and rack your steering wheel back and forth. The wheel should be locked in place, allowing only a slight range of mobility. This will help the extra lubricant within the power steering system to drain.
Watch the empty container. It should fill with old lubricant. Once the old lubricant has been flushed and you see clean fluid replacing it, you've finished the hard part.

Disconnect your hose and move the container. Replace the original reservoir hose. Pour new, clean power steering fluid into the reservoir. Rack your steering wheel a few more times to squeeze out air that might be trapped in the lines. Replace the filer cap and close your done.
Thank you for suing fixya and good luck

There should be a pressure switch for the power steering that regulates rpm' to the computer.
It should have an electrical connector on it and located on the rack and pinion assembley.

Ions have electric steering. There is no Reservoir. does your steering feel tight?
