Where do you add power steering fluid? I cant locate the reservoir.

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.

Look down under the fuse box or you could have electric power steering and you dont have to add fluid

There is a reservoir under the hood that stores power steering fluid. That is where you add the fluid. Most likely, yours will be located directly behind a drive belt pulley, attached directly to the power steering pump, and the cap should be marked for power stering fluid. It will contain a dipstick that has marks stating minimum and maximum fluid levels with the fluid either hot or cold. If you have to add to it often, you have a leak that needs to be repaired.

The power steering resover is under the alternator on these model cars your going to have look for it.

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 HAVE A RUPTURE PRESSURE LINE IF YOU HAVE NO POWER STEERING FLUID IN THE POWER STEERING RESERVOIR.LOCATE LEAK THEN BLEED POWER STEERING SYSTEM BY ADDING POWER STEERING TO RESERVOIR.DONT OVER FILL BY FULL COLD MARK ON POWER STEERING DIP STICK.ADD FLUID TO RESERVOIR WAIT A 2 MINUTES.CHECK FLUID LEVEL AGAIN.WHEN POWER STEERING FLUID LEVEL STOP DROPPING.START ENGINE LET IT RUN FOR 10 SECONDS.THEN TURN OFF ENGINE CHECK POWER STEERING FLUID ADD FLUID IF FLUID LEVEL DROPS. WHEN FLUID LEVEL STOP DROPPING.SAFELY RAISE SUPPORT VECHICLE FRONT WHEELS.START ENGINE.NOW TURN STEERING WHEEL GENTLY FROM STOP TO STOP MEANING LEFT TO RIGHT DONT HOLD IN POSITION.LET THE STOP TO STOP BE QUICK.CHECK POWER STEERING FLUID AFTER YOU HAVE TURN STEERING WHEEL ABOUT 7 STOP TO STOP.WHEN FLUID LEVEL STOP DROPPING YOU AT HOT MARK ON DIP STICK BLEEDING PROCESS COMPLETE.TURN OFF ENGINE LOWER VECHICLE BACK TO GROUND WAIT ABOUT 5 MINUTES CHECK YOUR FLUID LEVEL.IF FLUID LOOKS LIKE A TAN COLOR.YOUR POWER STEERING SYSTEM FULL OF AIR.TURN OFF VECHICLE LET VECHICLE SET A LONG WHILE TO AIR BUBBLES SETTLE DOWN LOOK FOR LEAKS AROUND POWER STEERING PUMP FRONT SEAL AND CHECK FOR LEAKS AROUND POWER STEERING LINES.

HEY DO THIS,YOU NEED TO BLEED SYSTEM. TO BLEED POWER STEERING SYSTEM.TO DO THIS.FILL THE POWER STEERING RESERVOIR TO COLD FULL MARK ON DIP STICK.WAIT A FEW MINITES,FLUID LEVEL DROP ADD MORE FLUID UNTIL REACH COLD MARK ON THE DIP STICK..WAIT FEW MINUTES.START ENGINE LET IT RUN FOR 2 OR 3 SECONDS.TURN OFF ENGINE CHECK POWER STEERING FLUID ADD MORE FLUID.DO THIS UNTIL FLUID LEVEL STOP DROPPING.WHEN FLUID LEVEL STOP DROPPING.SAFELY RAISE FRONT OF THE VECHICLE UNTIL FRONT WHEELS DONT TOUCH THE GROUND.START ENGINE UP.TURN THE STEERING WHEEL GENTLY FROM STOP TO STOP,CHECK THE RESERVOIR FLUID LEVEL LOOKS GOOD TURN OFF ENGINE LOWER VECHICLE .LOWER VECHICLE TO GROUND. LET VECHICLE SET FOR 2 MINUTES CHECK POWER STEERING FLUID LEVEL.IF STILL LOW ADD LITTLE MORE.TO THE COLD FULL MARK ON DIP STICK. DONT OVER FILL BECAUSE FLUID LEVEL RISES WHEN IT GET HOT.WHEN DONE IF STEERING WHEEL STILL FEEL HARD TO TURN YOU SEE AIR BUBBLES IN FLUID THATS WHEN FLUID HAS A TAN LOOKING COLOR WAIT 5 MINUTES AND.REPEAT THE BLEEDING PROCESS. DONT DRIVE OR OPERATE VECHICLE ON HIGHWAY UNTIL POWER STEERING HAS NORMAL OPERATION.

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

Make sure that your vehicle is parked on a level surface and the engine is cool before you check fluid levels. Power steering fluid and other fluids read at different levels when warm instead of cool. Locate the power steering fluid reservoir. It is located under the hood of your Toyota Corolla on the passenger side next to the engine. The reservoir is connected to the power steering pump. Remove the cap and use the dipstick to check the fluid level. For the most accurate reading, clean off the dipstick with a rag first, then re-insert and remove for the fresh reading. Add automatic transmission fluid or power steering fluid approved for use in Toyota vehicles if the fluid is below the low level mark. Add fluid gradually to keep for over filling the reservoir.
this will help.thanks.

theres a plastic reservoir located on the side of the engine wall look at the cap it should say power steering fluid on it .....
