In this write-up I"ll it is in explaining the process on exactly how I choose to flush power steering fluid. (Also chilton"s way) ns performed that on mine 2002 Pontiac grand Prix. This need to be performed, in mine opinion, as frequently as you change your transmission fluid; yet GM does not specify one interval. Most civilization do this when their pump starts make noise, yet I"m act it as preventative maintenance. Besides, mine old fluid had a scorched smell to it. Mine pump was totally silent before, and still is after the flush. It"s not difficult to do, but due to the fact that our reservoirs room in an unthinkable place (behind the engine on the passenger side because that those who carry out not know) you may want to it is in under the car. Friend may be able to do everything from above, yet you have to acquire under to put a pan down, and the process is less complicated with the wheels off the floor anyway, so that"s exactly how I"ll be explaining the procedure. If excellent correctly, no air will be presented to the system during this process.This procedure if very efficient because never will any old liquid that goes v the rack, go back into the reservoir. The bespeak of fluid would be: Reservoir, pump, rack, and back to the reservoir. I remove the return line the goes back to the reservoir therefore it will not cycle. I"ve watched a an approach of removing liquid from the reservoir and replacing through new, starting, and repeating. The problem with the is the reservoir account for about 1/4 the the system capacity. For this reason the an initial flush would readjust 1/4 the the fluid, climate the following is already partially brand-new fluid, and also so on. Never would you be able to flush that mechanism out completely, there will always be a percent of old fluid left that would keep obtaining smaller eventually however never completely. That is good to flush totally to remove particles or sediment in the system that will wear the components. Over there is no filter in the power steering system. Being that this is a return line, over there is no pressure. It is actually often referred to as the suction line.Things you will certainly need: 2-3 quarts of brand-new power steering liquid (Use power steering liquid with avoid leak additive if your device leaks. Many 100K+ equipment leak into the rack boots and you might not understand it), Jack+Jack Stands, 10 mm Socket+Ratchet, Pliers, "3/8"" fake hose"(To keep fluid from coming the end of the reservoir. A bag and rubber band might work too), Drip pan, long funnel, a medium sized container to monitor the purged fluid"s color, towels.Things that will certainly help:Fluid siphon pump(some way to acquire old liquid out of the reservoir), Flashlight, gloves, cardboard to put down before starting, 3/8ths heat to expand the return line into a container

Raise and support the auto with jack stands. Put a tarp/cardboard under the vehicle if you don"t desire to make a mess. Remove the coolant overflow tank and set it aside for easier access to the power steering reservoir (10mm). Remove the strength steering cap and remove the old fluid. You deserve to do this v a vacuum bleeder tool, a hand siphon pump, or also a turkey baster. If you really don"t have any type of of these, you may remove the return line and also the liquid will recording out. I suggest going through the other methods over this since it will drip anywhere the frame and cv shaft.Once the old liquid is removed, eliminate the return line from the reservoir, and also direct it right into a container. Some liquid will come out. I supplied some old infection cooler line to extend it by inserting it right into the return hose. Then make sure liquid will no come the end of the reservoir wherein you eliminated the return hose. I provided some infection cooler hose with a bolt in the various other end.

You deserve to see the reservoir in ~ the other end of the hose through a bolt in it. If friend don"t have 3/8"ths hose, find some method to plug that inlet hole. A bag and rubber band might work too. You can additionally see the return heat being redirected through a steel line. If you don"t have actually a line choose this, find some method to straight the hose right into a pan or bucket. Fluid will come out of it reasonably quickly. Place a pan or bucket under the return line.
*
currently you deserve to fill the reservoir with new fluid utilizing a long funnel. To fill it until it"s practically to the top.
*
Now you will certainly be beginning the car for short amounts of time. Take keep in mind that the reservoir empties quickly. It only takes around 3 seconds from the time you start cranking to fully drain it.Since the wheels space in the air, you will have the ability to do this process quickly. Start the auto for just 2 seconds, then shut that off. Refill the reservoir completely. Check the shade of the liquid in the flushing container, and dump the into one more container for this reason you can monitor the present fluid color.My very first flush:
*
start the car again for 2 seconds, and shut it off. To fill the reservoir, and also check the fluid condition. It have to start coming to be clear by the 2nd time. I might see the fluid coming out of the return line very slowly was clearer than the fluid in the container, so the brand-new fluid had already made that through.Now that the new fluid has made the through, friend will rotate the wheel while starting for the 2 second period.Start the automobile for 2 seconds, throughout that time, rotate the wheel totally to one direction, and also shut it off as soon as you acquire there. This need to be a very quick process. You can start turning the wheel when it"s cranking.Here is a quick video I made of this procedure to aid describe the duration: Flushing strength Steering liquid - YouTubeFill the reservoir. Friend will see that the flushed fluid is now dark again. Transforming the wheels displaces an ext old liquid in the rack. Keep starting and turning lock to lock quickly until the fluid in the container i do not care close come the new fluid color.My 3rd time flushing while turning the wheel: It"s gaining lighter.
*
My fourth time flushing while transforming the wheel(6 complete flushes): This is irradiate enough. My new Valvoline fluid is a an extremely light yellow color. At the moment I purged this, the fluid slowly dripping the end of the return line to be a little clearer than the liquid in the container. (Unmixed through the dirtier fluid) This is after a total of flushing double without transforming the wheel come start, and also 4 time while transforming it. I provided 2 quarts during this process, and it was currently clean sufficient for me.

Once you"re comfortable with the liquid color, do not add any an ext fluid come the reservoir since you will have to remove the dummy water tap from the reservoir and also fluid will come out. Install the reservoir cap(to produce a slight vacuum so the remaining fluid in the reservoir won"t intake out), remove the dummy hose, and quickly install the initial return hose. Make sure to on slide the water tap clamp earlier over the finish of the hose. Wipe up any drips to accurately examine for leaks later. To fill the reservoir just to where shown on the dipstick ~ above the cold fill line, and install the cap. Start the car and also turn the wheels earlier and forth several times. Shut that off, and also make certain the liquid level is still whereby it have to be. Mine stayed the same, prove I introduced no air to the system during the flush. Also if air to be introduced, starting the car and transforming the wheels back and forth numerous times is a bleeding process. I would quite not need to bleed it because some systems deserve to be tricky.Reinstall the coolant overflow tank if you removed it, and install the two 10mm nuts. Reduced the vehicle ago down.Fluid colors: ~ above the left is the initial fluid, the center is the last do the washing up color, and also on the right is a tiny sample of the current fluid color. An extremely much prefer the brand-new fluid color.

I supplied 2.2 quarts throughout the flush. The two on the left is the old liquid put earlier into the containers, and on the appropriate is brand-new fluid. You deserve to see that the shade of the new fluid is no clear, it"s similar to the shade that"s in mine reservoir.

So, that"s just how to flush a power steering system on a 3.8L. This should rise the life of the contents such as the pump and also rack and also pinion. Because that what it"s worth, ($10-$15) this is a good way to keep your strength steering system. The may also give girlfriend .1 better mpg early to much better lubrication and also less warm created.
