In this write-up I"ll be explaining the procedure on exactly how I choose to flush power steering fluid. (Also chilton"s way) ns performed the on my 2002 Pontiac cool Prix. This should be performed, in my opinion, as often as you readjust your infection fluid; however GM does no specify one interval. Most human being do this once their pump starts do noise, but I"m act it as preventative maintenance. Besides, mine old liquid had a charred smell come it. Mine pump was completely silent before, and also still is after ~ the flush. It"s not difficult to do, but because our reservoirs are in one unthinkable place (behind the engine ~ above the passenger side for those who perform not know) you may want to it is in under the car. Friend may be able to do every little thing from above, however you have actually to gain under to put a pan down, and also the procedure is less complicated with the wheels turn off the soil anyway, therefore that"s just how I"ll it is in explaining the procedure. If excellent correctly, no air will certainly be introduced to the system throughout this process.This procedure if really efficient because never will any kind of old fluid that goes v the rack, go ago into the reservoir. The stimulate of fluid would be: Reservoir, pump, rack, and ago to the reservoir. I eliminate the return line the goes back to the reservoir for this reason it will not cycle. I"ve seen a an approach of removing fluid from the reservoir and replacing through new, starting, and repeating. The difficulty with the is the reservoir accounts for about 1/4 of the device capacity. Therefore the first flush would adjust 1/4 of the fluid, climate the next is currently partially brand-new fluid, and so on. Never would you have the ability to flush that device out completely, there will constantly be a percent of old liquid left that would certainly keep gaining smaller eventually but never completely. That is an excellent to flush fully to eliminate particles or sediment in the device that will certainly wear the components. Over there is no filter in the strength steering system. Being the this is a return line, there is no pressure. That is actually frequently referred to as the suction line.Things you will need: 2-3 quarts of brand-new power steering liquid (Use strength steering liquid with avoid leak additives if your device leaks. Most 100K+ solution leak right into the rack boots and you might not recognize it), Jack+Jack Stands, 10 mm Socket+Ratchet, Pliers, "3/8"" dummy hose"(To keep fluid from coming the end of the reservoir. A bag and rubber band might work too), Drip pan, lengthy funnel, a medium sized container to screen the purged fluid"s color, towels.Things that will certainly help:Fluid siphon pump(some means to get old liquid out that the reservoir), Flashlight, gloves, cardboard to placed down prior to starting, 3/8ths line to extend the return line right into a container

Raise and support the automobile with jack stands. Put a tarp/cardboard under the vehicle if girlfriend don"t desire to do a mess. Eliminate the coolant overflow tank and collection it aside for easier access to the power steering reservoir (10mm). Remove the power steering cap and remove the old fluid. You deserve to do this through a vacuum bleeder tool, a hand siphon pump, or even a turkey baster. If you yes, really don"t have any kind of of these, you might remove the return line and the liquid will recording out. I imply going with the other techniques over this due to the fact that it will certainly drip anywhere the frame and cv shaft.Once the old liquid is removed, eliminate the return line from the reservoir, and direct it right into a container. Some liquid will come out. I offered some old transmission cooler line to extend it by inserting it into the return hose. Then do sure fluid will no come out of the reservoir whereby you removed the return hose. I offered some transmission cooler hose with a bolt in the other end.

You can see the reservoir in ~ the other finish of the hose with a bolt in it. If you don"t have actually 3/8"ths hose, discover some means to plug that inlet hole. A bag and also rubber band might work too. Friend can additionally see the return heat being redirected with a stole line. If girlfriend don"t have a line prefer this, find some method to direct the hose into a pan or bucket. Fluid will come out of it relatively quickly. Place a pan or bucket under the return line.
*
now you have the right to fill the reservoir with new fluid making use of a long funnel. Fill it till it"s almost to the top.
*
Now you will certainly be beginning the vehicle for short amounts of time. Take note that the reservoir empties quickly. It just takes around 3 secs from the moment you start cranking to fully drain it.Since the wheels room in the air, you will be able to do this process quickly. Start the automobile for just 2 seconds, climate shut it off. Refill the reservoir completely. Examine the shade of the fluid in the flushing container, and dump that into another container for this reason you have the right to monitor the current fluid color.My very first flush:
*
begin the vehicle again for 2 seconds, and shut it off. To fill the reservoir, and also check the fluid condition. It must start ending up being clear by the 2nd time. I can see the fluid coming out of the return line really slowly to be clearer than the liquid in the container, therefore the new fluid had already made that through.Now that the brand-new fluid has made it through, friend will turn the wheel while starting for the 2 2nd period.Start the auto for 2 seconds, during that time, revolve the wheel totally to one direction, and shut it off as soon as you get there. This have to be a very quick process. You can start transforming the wheel if it"s cranking.Here is a quick video clip I make of this procedure to help describe the duration: Flushing power Steering liquid - YouTubeFill the reservoir. You will view that the flushed fluid is now dark again. Transforming the wheels displaces more old liquid in the rack. Keep starting and turning lock to lock conveniently until the liquid in the container i do not care close come the brand-new fluid color.My 3rd time flushing while turning the wheel: It"s acquiring lighter.
*
My fourth time flushing while turning the wheel(6 total flushes): This is light enough. My brand-new Valvoline liquid is a really light yellow color. At the time I flushed this, the liquid slowly dripping the end of the return line was a tiny clearer 보다 the fluid in the container. (Unmixed through the dirtier fluid) This is after ~ a full of flushing double without transforming the wheel come start, and 4 times while turning it. I supplied 2 quarts during this process, and also it was already clean enough for me.

Once you"re comfortable through the liquid color, perform not add any much more fluid come the reservoir due to the fact that you will need to remove the dummy hose from the reservoir and fluid will come out. Install the reservoir cap(to develop a slim vacuum so the remaining liquid in the reservoir won"t intake out), eliminate the dummy hose, and quickly install the initial return hose. Make certain to on slide the water tap clamp earlier over the end of the hose. Wipe up any type of drips come accurately inspect for leaks later. Fill the reservoir just to where indicated on the dipstick top top the cold fill line, and also install the cap. Start the car and also turn the wheels earlier and forth numerous times. Shut it off, and also make certain the fluid level is still where it must be. Mine remained the same, prove I introduced no air come the system throughout the flush. Even if air to be introduced, starting the auto and transforming the wheels back and forth numerous times is a bleeding process. Ns would fairly not need to bleed it because some systems deserve to be tricky.Reinstall the coolant overflow tank if you removed it, and install the 2 10mm nuts. Lower the vehicle ago down.Fluid colors: on the left is the original fluid, the center is the last flush color, and on the best is a tiny sample of the current fluid color. Really much prefer the new fluid color.

I offered 2.2 quarts during the flush. The 2 on the left is the old fluid put back into the containers, and also on the right is new fluid. You have the right to see the the shade of the brand-new fluid is no clear, it"s just like the color that"s in mine reservoir.

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