In this write-up I\"ll be explaining the process on just how I like to flush power steering fluid. (Also chilton\"s way) i performed the on mine 2002 Pontiac cool Prix. This should be performed, in my opinion, as regularly as you adjust your transmission fluid; yet GM does no specify one interval. Most people do this as soon as their pump starts do noise, however I\"m law it as preventative maintenance. Besides, my old liquid had a burned smell come it. Mine pump was completely silent before, and also still is after the flush. It\"s not hard to do, but since our reservoirs room in one unthinkable ar (behind the engine on the passenger side for those who execute not know) you might want to be under the car. Friend may have the ability to do everything from above, however you have to get under to placed a pan down, and also the procedure is much easier with the wheels turn off the soil anyway, therefore that\"s just how I\"ll be explaining the procedure. If done correctly, no air will certainly be presented to the system throughout this process.This process if very efficient since never will any type of old fluid that goes through the rack, go ago into the reservoir. The order of fluid would be: Reservoir, pump, rack, and earlier to the reservoir. I remove the return line the goes ago to the reservoir for this reason it will certainly not cycle. I\"ve viewed a an approach of removing fluid from the reservoir and also replacing v new, starting, and also repeating. The trouble with that is the reservoir account for around 1/4 that the device capacity. Therefore the first flush would adjust 1/4 the the fluid, then the following is currently partially new fluid, and also so on. Never would you be able to flush that system out completely, over there will constantly be a percent of old fluid left that would keep gaining smaller eventually but never completely. That is great to flush totally to remove particles or sediment in the system 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. It is actually often referred to together the suction line.Things you will need: 2-3 quarts of brand-new power steering liquid (Use power steering fluid with avoid leak additives if your system leaks. Many 100K+ systems leak into the rack boots and also you may not know it), Jack+Jack Stands, 10 mm Socket+Ratchet, Pliers, \"3/8\"\" fake hose\"(To keep fluid from coming out of the reservoir. A bag and rubber band may work too), Drip pan, lengthy funnel, a medium sized container to monitor the flushed fluid\"s color, towels.Things that will certainly help:Fluid siphon pump(some means to obtain old fluid out that the reservoir), Flashlight, gloves, cardboard to put down before starting, 3/8ths heat to expand the return line right into a container
Raise and also support the automobile with jack stands. Put a tarp/cardboard under the auto if you don\"t desire to do a mess. Eliminate the coolant overflow tank and set it aside for easier access to the power steering reservoir (10mm). Eliminate the power steering cap and remove the old fluid. You deserve to do this through 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 may remove the return line and also the liquid will recording out. I suggest going through the other approaches over this since it will certainly drip anywhere the frame and also cv shaft.Once the old liquid is removed, eliminate the return heat from the reservoir, and also direct it into a container. Some liquid will come out. I provided some old infection cooler line to expand it by inserting it right into the return hose. Then make sure liquid will no come the end of the reservoir whereby you eliminated the return hose. I supplied some infection cooler hose v a bolt in the other end.

You can see the reservoir in ~ the other end of the hose with a bolt in it. If you don\"t have 3/8\"ths hose, find some method to plug that inlet hole. A bag and also rubber band may work too. You can additionally see the return heat being redirected v a steel line. If you don\"t have a line choose this, discover some way to straight the hose into a pan or bucket. Fluid will come the end of it reasonably quickly. Position a pan or bucket under the return line.
now you can fill the reservoir with brand-new fluid making use of a long funnel. To fill it until it\"s nearly to the top.
Now you will certainly be beginning the vehicle for short quantities of time. Take keep in mind that the reservoir empties quickly. It only takes around 3 secs from the time you begin cranking to fully drain it.Since the wheels are in the air, friend will have the ability to do this procedure quickly. Begin the automobile for just 2 seconds, then shut it off. Refill the reservoir completely. Check the color of the liquid in the flushing container, and dump it into an additional container so you can monitor the present fluid color.My very first flush:
start the auto again for two seconds, and also shut it off. Fill the reservoir, and check the fluid condition. It must start coming to be clear through the 2nd time. I could see the fluid coming the end of the return line really slowly was clearer 보다 the liquid in the container, therefore the brand-new fluid had already made it through.Now that the new fluid has made that through, you will revolve the wheel while beginning for the 2 2nd period.Start the vehicle for 2 seconds, throughout that time, revolve the wheel completely to one direction, and also shut that off when you gain there. This have to be a really quick process. You deserve to start turning the wheel while it\"s cranking.Here is a quick video clip I made of this process to aid describe the duration: Flushing power Steering fluid - YouTubeFill the reservoir. Friend will view that the flushed liquid is now dark again. Transforming the wheels displaces an ext old liquid in the rack. Keep starting and turning lock come lock conveniently 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 acquiring lighter.
My fourth time flushing while transforming the wheel(6 total flushes): This is light enough. My brand-new Valvoline fluid is a really light yellow color. At the time I flushed this, the liquid slowly dripping out of the return line to be a tiny clearer 보다 the fluid in the container. (Unmixed with the dirtier fluid) This is ~ a full of flushing twice without turning the wheel come start, and also 4 time while turning it. I provided 2 quarts throughout this process, and also it was already clean enough for me.
Once you\"re comfortable v the fluid color, perform 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 slight vacuum therefore the remaining liquid in the reservoir won\"t recording out), eliminate the fake hose, and also quickly install the initial return hose. Make sure to slide the water tap clamp back over the finish of the hose. Wipe up any drips come accurately inspect for leaks later. Fill the reservoir only to where suggested on the dipstick top top the cold to fill line, and install the cap. Start the car and also turn the wheels earlier and forth number of times. Shut that off, and make sure the liquid level is still where it need to be. Mine stayed the same, proving I presented no air to the system during the flush. Even if air was introduced, starting the automobile and turning the wheels earlier and forth numerous times is a bleeding process. Ns would rather not need to bleed it since some systems can be tricky.Reinstall the coolant overflow tank if you gotten rid of it, and install the two 10mm nuts. Lower the vehicle ago down.Fluid colors: ~ above the left is the initial fluid, the center is the last flush color, and on the right is a small sample the the existing fluid color. Really much prefer the new fluid color.

I supplied 2.2 quarts during the flush. The two on the left is the old liquid put ago into the containers, and also on the appropriate is new fluid. You have the right to see the the shade of the brand-new fluid is not clear, it\"s similar to the color that\"s in my reservoir.
So, that\"s exactly how to do the washing up a strength steering device on a 3.8L. This should rise the life of the contents such as the pump and rack and pinion. For what it\"s worth, ($10-$15) this is a good way to maintain your power steering system. It may also give friend .1 much better mpg early out to much better lubrication and also less warm created.
