In this write-up I"ll be explaining the process on exactly how I favor to flush strength steering fluid. (Also chilton"s way) ns performed it on mine 2002 Pontiac cool Prix. This should be performed, in my opinion, as often as you adjust your infection fluid; yet GM does not specify an interval. Most people do this when their pump starts making noise, however I"m law it as preventative maintenance. Besides, mine old fluid had a scorched smell to it. My pump was completely silent before, and also still is after ~ the flush. It"s not difficult to do, but because our reservoirs are in an unthinkable location (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 have the ability to do whatever from above, but you have to gain under to put a pan down, and also the process is much easier with the wheels turn off the floor anyway, therefore that"s how I"ll be explaining the procedure. If excellent correctly, no air will certainly be introduced to the system during this process.This process if really efficient because never will any kind of old fluid that goes through the rack, go earlier into the reservoir. The bespeak of fluid would be: Reservoir, pump, rack, and ago to the reservoir. I remove the return line the goes earlier to the reservoir so it will not cycle. I"ve watched a method of removing liquid from the reservoir and replacing with new, starting, and also repeating. The difficulty with the is the reservoir accounts for about 1/4 that the device capacity. For this reason the an initial flush would change 1/4 the the fluid, climate the next is already partially brand-new fluid, and so on. Never ever would you have the ability to flush that mechanism out completely, over there will always be a portion of old fluid left that would keep acquiring smaller eventually yet never completely. That is great to flush totally to eliminate particles or sediment in the system that will wear the components. There is no filter in the strength steering system. Being that this is a return line, there is no pressure. The is actually regularly referred to together the suction line.Things you will need: 2-3 quarts of brand-new power steering fluid (Use power steering liquid with stop leak additive if your system leaks. Most 100K+ equipment leak right into the rack boots and also you might not know it), Jack+Jack Stands, 10 mm Socket+Ratchet, Pliers, "3/8"" dummy hose"(To keep fluid from coming out 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 help:Fluid siphon pump(some method to gain old fluid out of the reservoir), Flashlight, gloves, cardboard to placed down before starting, 3/8ths heat to extend the return line into a container
Raise and support the automobile with jack stands. Put a tarp/cardboard under the automobile if you don"t desire to make a mess. Eliminate the coolant overflow tank and collection it aside for easier accessibility to the power steering reservoir (10mm). Remove the power steering cap and also 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 kind of of these, you might remove the return line and the liquid will intake out. I imply going with the other methods over this since it will certainly drip anywhere the frame and also cv shaft.Once the old liquid is removed, remove the return line from the reservoir, and direct it right into a container. Some fluid will come out. I offered some old transmission cooler line to prolong it through inserting it right into the return hose. Then do sure fluid will no come the end of the reservoir where you eliminated the return hose. I supplied some transmission cooler hose with a bolt in the various other end.

You can see the reservoir at the other finish of the hose with a bolt in it. If you don"t have actually 3/8"ths hose, uncover some way to plug the inlet hole. A bag and also rubber band might work too. Girlfriend can also see the return line being redirected with a stole line. If girlfriend don"t have a line choose this, discover some method to straight the hose right into a pan or bucket. Fluid will come out of it fairly quickly. Place a pan or bucket under the return line.
now you can fill the reservoir with new fluid making use of a lengthy funnel. Fill it till it"s virtually to the top.
Now you will be starting the vehicle for short amounts of time. Take keep in mind that the reservoir empties quickly. It just takes about 3 secs from the moment you start cranking to totally drain it.Since the wheels room in the air, you will be able to do this procedure quickly. Start the vehicle for simply 2 seconds, climate shut that off. Refill the reservoir completely. Inspect the color of the liquid in the flushing container, and dump it into another container so you have the right to monitor the current fluid color.My an initial flush:
begin the car again for 2 seconds, and also shut that off. Fill the reservoir, and check the fluid condition. It need to start ending up being clear through the second time. I can see the fluid coming the end of the return line very slowly to be clearer than the fluid in the container, for this reason the brand-new fluid had currently made the through.Now that the new fluid has made that through, you will turn the wheel while beginning for the 2 2nd period.Start the automobile for 2 seconds, throughout that time, rotate the wheel fully to one direction, and shut the off when you obtain there. This must be a very quick process. You deserve to start turning the wheel when it"s cranking.Here is a quick video clip I make of this procedure to assist describe the duration: Flushing power Steering liquid - YouTubeFill the reservoir. Girlfriend will view that the flushed liquid is currently dark again. Turning the wheel displaces an ext old liquid in the rack. Keep beginning and transforming lock come lock easily until the fluid in the container i do not care close come the new fluid color.My 3rd time flushing while transforming the wheel: It"s acquiring lighter.
My fourth time flushing while transforming the wheel(6 complete flushes): This is light enough. My brand-new Valvoline fluid is a an extremely light yellow color. At the time I purged this, the liquid slowly dripping out of the return line was a small clearer 보다 the liquid in the container. (Unmixed through the dirtier fluid) This is ~ a full of flushing double without transforming the wheel come start, and also 4 time while transforming it. I offered 2 quarts during this process, and also it was already clean sufficient for me.
Once you"re comfortable through the fluid color, execute not include any more fluid to the reservoir due to the fact that you will have to remove the dummy water tap from the reservoir and fluid will come out. Install the reservoir cap(to produce a slim vacuum therefore the remaining fluid in the reservoir won"t intake out), remove the fake hose, and quickly download the initial return hose. Make sure to on slide the water tap clamp back over the finish of the hose. Wipe up any drips to accurately inspect for leaks later. Fill the reservoir only to where indicated on the dipstick ~ above the cold to fill line, and also install the cap. Start the car and also turn the wheels earlier and forth number of times. Shut it off, and make sure the fluid level is still where it must be. Mine stayed the same, proving I introduced no air come the system during the flush. Even if air to be introduced, beginning the automobile and turning the wheels ago and forth number of times is a bleeding process. Ns would rather not need to bleed it due to the fact that some systems have the right to be tricky.Reinstall the coolant overflow tank if you eliminated it, and also install the two 10mm nuts. Lower the vehicle ago down.Fluid colors: on the left is the initial fluid, the middle is the last do the washing up color, and on the best is a little sample the the present fluid color. Really much prefer the new fluid color.

I offered 2.2 quarts throughout the flush. The two on the left is the old liquid put back into the containers, and on the ideal is new fluid. You can see that the color of the brand-new fluid is not clear, it"s similar to the shade that"s in mine reservoir.
So, that"s just how to flush a strength steering mechanism on a 3.8L. This should rise the life of the contents such as the pump and rack and pinion. Because that what it"s worth, ($10-$15) this is a good way to preserve your power steering system. It may even give girlfriend .1 far better mpg early out to better lubrication and also less warmth created.
