In this write-up I"ll be explaining the process on how I like to flush strength steering fluid. (Also chilton"s way) i performed that on my 2002 Pontiac cool Prix. This must be performed, in mine opinion, as often as you change your infection fluid; yet GM does no specify an interval. Most world do this when their pump starts do noise, yet I"m act it together preventative maintenance. Besides, mine old liquid had a burnt smell to it. My pump was completely silent before, and also still is after the flush. It"s not hard to do, but because our reservoirs room in an unthinkable location (behind the engine top top the passenger side because that those who execute not know) you might want to be under the car. You may have the ability to do every little thing from above, but you have to gain under to placed a pan down, and the process is less complicated with the wheels turn off the soil anyway, so that"s just how I"ll it is in explaining the procedure. If excellent correctly, no air will certainly be introduced to the system during this process.This process if very efficient because never will any kind of old fluid that goes through the rack, go back into the reservoir. The order of fluid would be: Reservoir, pump, rack, and earlier to the reservoir. I eliminate the return line the goes back to the reservoir for this reason it will certainly not cycle. I"ve seen a method of removing fluid from the reservoir and also replacing through new, starting, and also repeating. The problem with that is the reservoir accounts for about 1/4 that the device capacity. So the very first flush would change 1/4 the the fluid, then the following is already partially brand-new fluid, and also so on. Never would you be able to flush that device out completely, there will always be a percent of old fluid left that would keep obtaining smaller eventually however never completely. The is good to flush completely to eliminate particles or sediment in the system that will certainly wear the components. Over there is no filter in the power steering system. Being that this is a return line, there is no pressure. It is actually often referred to together the suction line.Things you will certainly need: 2-3 quarts of new power steering liquid (Use strength steering fluid with protect against leak additive if your mechanism leaks. Most 100K+ solution leak into the rack boots and you may not know it), Jack+Jack Stands, 10 mm Socket+Ratchet, Pliers, "3/8"" fake hose"(To keep liquid from coming the end of the reservoir. A bag and rubber band may work too), Drip pan, lengthy funnel, a tool sized container to screen the flushed fluid"s color, towels.Things that will certainly help:Fluid siphon pump(some way to obtain old fluid out that the reservoir), Flashlight, gloves, cardboard to placed down prior to starting, 3/8ths line to prolong the return line right into a container
Raise and support the auto with jack stands. Placed a tarp/cardboard under the automobile if you don"t desire to make a mess. Remove the coolant overflow tank and collection it aside because that easier access to the strength steering reservoir (10mm). Remove the strength steering cap and also remove the old fluid. You have the right 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 of these, you may remove the return line and also the liquid will intake out. I suggest going with the other approaches over this since it will certainly drip everywhere the frame and cv shaft.Once the old liquid is removed, remove the return heat from the reservoir, and direct it right into a container. Some liquid will come out. I used some old infection cooler heat to extend it through inserting it into the return hose. Then do sure fluid will not come the end of the reservoir whereby you eliminated the return hose. I supplied some transmission cooler hose with a bolt in the other end.

You can 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 the 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 like this, discover some way to direct the hose into a pan or bucket. Liquid will come out of it fairly quickly. Position a pan or bucket under the return line.
currently you can fill the reservoir with new fluid making use of a lengthy funnel. Fill it until it"s almost to the top.
Now you will be beginning the auto for short amounts of time. Take note that the reservoir empties quickly. It just takes about 3 secs from the time you start cranking to totally drain it.Since the wheels are in the air, you will be able to do this process quickly. Begin the automobile for simply 2 seconds, climate shut that off. Refill the reservoir completely. Examine the color of the fluid in the flushing container, and also dump the into one more container therefore you can monitor the present fluid color.My very first flush:
start the car again for two seconds, and shut that off. Fill the reservoir, and check the fluid condition. It have to start coming to be clear by the 2nd time. I might see the liquid coming the end of the return line an extremely slowly to be clearer 보다 the liquid in the container, therefore the new fluid had currently made the through.Now that the new fluid has actually made it through, friend will turn the wheel while starting for the 2 second period.Start the auto for 2 seconds, throughout that time, rotate the wheel totally to one direction, and shut it off as soon as you get there. This must be a really quick process. You have the right to start transforming the wheel when it"s cranking.Here is a quick video I make of this process to aid describe the duration: Flushing power Steering liquid - YouTubeFill the reservoir. Friend will view that the flushed liquid is now dark again. Turning the wheels displaces more 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 acquiring lighter.
My 4th time flushing while turning the wheel(6 total flushes): This is light enough. My new Valvoline liquid is a very light yellow color. At the time I flushed this, the liquid slowly dripping the end of the return line to be a small clearer than the fluid in the container. (Unmixed through the dirtier fluid) This is ~ a full of flushing double without turning the wheel come start, and 4 time while transforming it. I used 2 quarts throughout this process, and also it was already clean enough for me.
Once you"re comfortable through the fluid color, execute not add any much more fluid to the reservoir since you will need to remove the dummy hose from the reservoir and also fluid will certainly come out. Download the reservoir cap(to develop a slight vacuum so the remaining fluid in the reservoir won"t recording out), eliminate the dummy hose, and quickly install the initial return hose. Make certain to slide the hose clamp earlier over the end of the hose. Wipe up any drips to accurately examine for leaks later. To fill the reservoir just to where indicated on the dipstick top top the cold to fill line, and install the cap. Begin the car and turn the wheels earlier and forth several times. Shut the off, and make sure the fluid level is still where it must be. Mine stayed the same, proving I presented no air to the system during the flush. Also if air to be introduced, beginning the auto 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 2 10mm nuts. Lower the vehicle ago down.Fluid colors: on the left is the initial fluid, the middle is the last flush color, and on the best is a little sample that the present fluid color. Very much favor the brand-new fluid color.

I used 2.2 quarts during the flush. The two on the left is the old liquid put ago into the containers, and on the ideal is new fluid. You have the right to see that the shade of the new fluid is no clear, it"s as with the shade that"s in mine reservoir.
So, that"s exactly how to flush a strength steering system on a 3.8L. This should increase the life that the materials such as the pump and rack and pinion. Because that what it"s worth, ($10-$15) this is a an excellent way to maintain your power steering system. That may even give you .1 far better mpg due to better lubrication and also less warm created.
