Power Steering

Power steering provided mechanical steering assistance to the drivers of most land vehicles, including automobiles and trucks. Today, most power steering systems use hydraulic system in order to maneuver the vehicle’s wheels.

What will happen if you poured Power Steering Fluid in Brake oil reservoir some of the brake oil were already in the tank and you start the engine but did not push the brake pedal?

Use a Turkey baster to remove all the fluid in the reservoir then use a rag to clean the reservoir of anything that remains. Now refill the reservoir with clean brake fluid.

I would also recommend that the brake system be bleed to remove the old brake fluid. As it is a recommended the Fluid should be replaced as a preventive maintenance service, and may need replacement every two years or 24,000 miles.

There is a tool available at auto parts store to help you D.I.Y this or you can take it to someone and have it done.

Do formula 1 cars have power steering?

As per the Formula 1 website 2012/08/04: " Power steering systems are allowed, but these must not be electronically controlled or powered. Four-wheel steering is forbidden. The car's steering wheel, steering column and steering rack all have to pass an FIA impact test."

Why would the power steering make noise even after fluid has been added?

Power steering noiseWhen the fluid is low and you add some, it may still need more after you run it for awhile. The reason is that as the pump pumps the fluid through the lines, this also normally pushes any air out the lines. Keep filling and checking after you start the car and turn the wheel from side to side all the way.
  • The bigger question is why do you need to add fluid? After you locate and fix that leak, you can address the whine. If it is a Ford, it may be somewhat normal. Like Drazi said, "It may be air trapped in the line." Or the pump may be damaged from running it dry, or there is bilge in the line, starving the pump. Let's assume you have kept up on the maintenance and have flushed the fluid when it was dirty. Let's also assume that the pump is not damaged and you have found and fixed any leaks. Try this: pull the fluid out of the reservior and add one bottle of Lucas brand power steering additive, and top with power steering fluid. I have found this stuff pretty good at resolving many power steering problems. I'm not a big supporter of "Snake Oil", but have had good luck with it.
  • If it's a Ford, it's because they use plastic parts in their casings, though most other car companies do the same. If that's not the case, then your pump is receiving too much stress from turning. Try lubing up the chassis and changing the fluid completely. It wouldn't hurt to check your lines either. Sometimes blockage can cause too much stress on the pump too.
  • First thing is why are you adding fluid. If it has a leak, then I would address that problem first. A pump will not bleed air out of the system if it is leaking. If everything seems to be okay and your pump still whines, then replace the pump, preferably with a new one from the dealer. The so-called rebuilt pumps that you can buy from places like Autozone, O'Reilly, etc. are cheaply rebuilt, especially if it's a Ford. They don't bleed out air properly, resulting in improper pump pressures. A good pump will bleed out almost immediately, with the turn of the wheel a few times. If it doesn't, then your pump will more than likely never completely bleed out. Buy a new pump from the dealer--it costs more, but if you're like me and don't like the noise, then it's worth it.
  • You probably have air trapped in the power steering fluid system. Bleed the air out by revving the engine to about 1500-2000 rpms and turning the steering wheel almost all the way from one side to the other a few times. This should bleed out the air and take care of your problem.
  • If the noise is similar to that of a dry bearing, then the problem is probably the power steering pump itself. If the noise you hear has a "click, click, click" to it when you make turns in your vehicle, then the problem is more-than-likely your CV joints. If the noise is screeching, check your belt for wear-and-tear and proper tension (see owner's manual), and the pulleys that the belt turns, including the air conditioning compressor motor and its clutch/pulley.

I just wanted to add another two cents about the topic of bleeding or burping the power steering system:

1. Know what type of power steering fluid is needed for your car. Some power steering pumps can use automatic transmission fluid, others have specific power steering fluid for each car, i.e. Honda requires and suggests that you use Honda's brand of power steering fluid (see owner's manual). Make sure you know, or the warranty from the dealership or from the parts store may be voided.

2. Before attaching the power steering belt, fill pump with required amount and type of fluid (see owner's manual), and then turn the pulley wheel by hand a few times. This helps cut down on dry turns before they can happen. If more power steering fluid is needed, fill accordingly.

3. Attach the power steering belt with proper amount of tension (see owner's manual).

4. Turn vehicle on and proceed to turn the steering wheel all the way right and left 3-4 times.

5. Turn the vehicle off, and examine that the belt tension is acceptable, and again check the level of fluid and fill accordingly.

6. Always, always check your owner's manual before performing any maintenance on your vehicle. An educated car owner is a safe car owner!

Another possibilityHow long has the pump run without fluid? There could be damage inside to the cam and rotor (assuming it's a vane type pump), or to the plates, or it could be cavitating due to the ingress of air -- possibly why the fluid leaked out in the first place.


I too experienced very loud whining noise from my 93 Ranger 3.0's power steering pump at idle, and even louder when turning the steering wheel even a little bit in either direction. I changed the fluid but there was no change in noise. I read in a Ranger forum that if you add some STP oil treatment (yes, STP OIL TREATMENT), not the whole can, it would help. I decided to give it a try and sure enough it has reduced the noise greatly. It didn't completely eliminate it but people no longer stare at my vehicle at red lights because of the noisy pump. That was embarrassing! Ford's pump must be partly to blame since the problem is so rampant among all their various models.

By the way, Mercury is supposed to begin being phased out (discontinued) beginning in 2010 and completely gone by 2012. Only Ford and Lincoln will remain. Just thought ya'll might want to know that since your Mercury's value will likely plummet as that kill-off nears. However, those of you who have a stiffy for Mercs may get a good deal on one before they are gone. I personally don't think they are "all that". Fords in general are pretty low market in build and longevity. I used to favor GM but switched to Honda products in the 90s, they are very long-lived. My latest is a Jaguar and I'm quite happy with it. Yes I know they were owned by Ford and now by Tata Motors but the design is all Jag.

How do you replace the power steering pump on a Taurus - Sable?

Disconnect negative battery cable, remove coolant overflow tank, unbolt alternator and place it forward of the front valve cover,there are two studs with nuts and one bolt holding the steering pump to the engine.In order to get to the bolt you must first unbolt and remove the serpentine belt tensioner because the bolt is behind and under it. Suggest the idler pully be removed for better access to everything. Once the idler and tensioner are removed, the PS pump PULLEY must be removed or broken off (its made of plastic) OR remove the two nuts from the studs and remove the bolt that was hidden by the tensioner. Slide the pump assembly forward so that you can access the studs with vice grips and remove them this way OR take two nuts that are the correct size for the studs,tighten them against each other and rotate the inner nut counterclockwise til the stud is out....the fun part is trying to get an open end wrench in there....I recommend vice grip from above. The studs have to come out if you desire to remove the pump intact with the pulley attached, otherwise it will not have any clearance to come out. A new pulley costs $9.95 at advance auto, power steering pump about $45 same place. Plastic pulley must be pressed on and cannot be done with the bolt, washer and nut supplied with the pulley unless you lube the Hell out of the pulley, break a coupleof pulleys because the instructions are Crap. Take the works to an auto machine shop and let them press it on. Best way to get the pulley off the old pump is by breaking the thing off with a hammer so you have it free of the mount and with you for exchange (core charge is $35). The tool recommeded for removing the old pulley is a hair puller and all you will do is strip the threads in the pulley without budging the plastic piece of junk.Good luck, it took me two pulleys and lots of cussing to learn what I have written here. PS, don't forget to change the $18 power steering pump filter(FOR REAL)on the drivers side clipped to the frame.

a good book is haynes auto repair for a mercury

first you remove the pulley with a pulley removel tool you should be able to rent one from parts store.then remove lines,then pump

I am replacing mine today..the pump itself will come with all the information you need except the fact that you need a special puller to remove the power steering pully. I tryed the conventional three prong puller and found the 4" is to big to get in there to grab thre front of the pully due to the low placement and the body and air conditioner lines in the way..I am on my way back to the auto parts store to see if I can purchase the right puller..back later with price and availability and how it worked out...good luck terry

you need to purchase a puller set.


I found some instructions in a "Haynes Repair Manual" for the Taurus and Sable. The manuals are available at auto parts stores and in many public libraries.

I did not need to buy the puller set. The Auto Zone in my neighborhood offers free tool rental, and they had the puller set that I needed. They asked for a deposit when I picked up the tools, and refunded the full deposit when I returned the tools.

same in my town, as the one above, about the renting of tools. auto zone , I've noticed , is the best place and one you can trust more than most stores, for tool rentals. do NOT , however, do it *redneck style* like my husband does, because we never have the $50 plus for the rental in between pay periods, by hammering it off. it is BAD!when i found out how he always got them off wihtout a *pulley puller* set, i asked him how he did it without messing it up. he responded, "VERY CAREFULLY!" my mother-in-laws b/f was not so careful, and it eventually costed 300 dollars in parts alone and 6 months worth of frustration fixing the botched job, just so we could replace the water pump because someone welded the pulley onto the pump to make it stay on, which is NOT by ANY means, exceptable on ANY car. it causes far more problems than the imediate fix. If not taken off properly, you can not put it back on and have it stay there. it will fly off and shred your belt. my sister went through 3 belts before i found out what they did and theyre 25 a peice.

you need a special tool. puller / installer. rent it at Auto Zone for +/- $35

Go to a automotive supply store and ask for a Haines auto repair manual for your make year and model of car. It will show you, step by step how to do any repair to that particular car, with photos and a complete description of how to take it apart and put it back together again.

The best few dollars that you will ever spend.

you need a power steering pump pulley puller and installer kit. go to your local parts store. theyll have one.

What is Ford m2c41-a oil for power steering pumps?

M2C41A is the Original Equipment Manufacturers Specifications for the type of oil to go into the system. M2C41A is not engine oil; it is a type of hydraulic oil. You do not need to use Ford M2C41A, you just have to find an alternative oil that meets Ford's Specifications. You should be fine using a Universal Tractor Fluid that meets SAE 10-W30 classification, just make sure it meets OEM M2C41A Specifications . DO NOT USE ENGINE OIL it is not the same.

Where is the power steering module on a 05 cobalt?

I believe it's located underneath the steering wheel. If you take off the panel just behind the steering wheel (pull hard, but be careful of the wire connected to the trunk release button inside the coin box) you should be able to see it easily. It's a black box, about 4" x 4" or so that says "Koyo" on it and you can see a little piece of a computer chip popping out the top righthand side. Hope this helps!

Why would a diesel car lose power?

dirty fuel filter, needs oil change.

Answerloss of compresson ie. worn rings, leaking head gasket, burnt valves

incorrectly adjusted linkage to foot pedal to maifold

bad fuel pump, dirty fuel or air filter, dirty injectors, clogged exhaust or worn turbo,bad or dirty EGR valve or cat convertor on models so equipped

AnswerFirst and foremost, air filter. I have a diesel truck that experienced the same problem. You might see excessive smoke as well when this is happening. Change your air filter. You should be changing it at least once a year anyways and maybe even more if your dealing with dry desert like conditions. AnswerI once had a diesel rabbit that was killed by a sucession of bad mechanics including a dealership and so called radiator specialists. Loss of power came on along with overheat on drives over fifteen minutes. It turned out that half of the radiator was blocked. The slow death came on because the raditor was half working. Whne my engine was changed at a junk yard, the juhnk yard mechanic discovered the problem that killed my original engine and was never properly diagnosed by the dealership and the so called radiator can colling specialists. This may not be your answer, I hope it is for someone drawn to your inquiry. answer2 things will stop a diesel DIRTY fuel and a DIRTY aircleaner but if weather is extremely cold, diesel will gell (freeze) and engine will lack power until diesel warms up Answerperhaps your turbo has blown if it is a TD TDi or CDTI etc..

Why is your steering wheel hard to turn?

Your power steering has a lot to do with the way your car handles. A sudden change in steering could be any/all of the following: low fluid, a broken belt (there is a belt that connects the engine's main drive pulley to the power steering, alternator, air conditioning, etc. pulleys) or the power steering pump went bad. Before you take your car to the shop, check the fluid and the belts to make sure they are OK. Note that loose belts are the same as broken belts. The belt MUST have the correct tension in it for it to work properly. In virtually all modern cars, belt tension is set with a spring loaded pulley that should always maintain the correct tension. You should check out the belt tensioner too. If all these check out properly, then the power steering pump is the next most likely culprit. Finally, the power steering rack - the thing that couples the hydraulic pressure from the power-steering pump into the steering mechanism - may need replacement or rebuilding.

Does the 1998 Saturn sl2 have power steering?

assuming your vehicle is equipped with powersteering, yes. to find out for sure you will need to open your hood and look in engine compartment. there should be, in the upper left corner of the engine, a small black cap that says... Power Steering on it. it will be sitting ontop of a white colored fluid container. This would be your power steering pump. Twist the black cap and pull upwards. the cap will have a stick fastened to the bottom of it with a fluid level indicator mark. be sure the fluid is up to that mark, or very close to it. if not, you may need to purchase some power steering fluid.

How do you change power steering fluid?

Simply withdraw only the fluid that's readily accessible in its small reservoir, and replace that portion with fresh fluid. You'll be doing this several times over a week or so until the fluid color looks normal. To use this technique, you first have to acquire the proper tool. It's sold as a "fluid removal/transfer tool" or battery filler, and resembles a turkey baster (but that's made of different materials, so don't use one of those from your kitchen). You'll also need to purchase the proper type and amount of power steering fluid and refill to the proper level, start your engine then cycle the steering left then right and recheck level.
Unless you have contaminated fluid (or several 100K miles), you should not need to change it. How to answer:

The following procedure will work in most cases (no vehicle specifics given)

If you're asking how to do it you should give vehicle specifics, year, make model & engine size. On most vehicles the best way is to drain the reservoir if you can then disconnect the return line at the reservoir. Get a few feet of hose the same size as the return line and use a hose connector or vacum line connector and connect the length of hose to the return line. Put the end of the hose in a large (1 Gal.) container. Make sure the line connector won't come apart as you will have a flood of oil everywhere if it does. Open the lid on the reservoir and fill it up with new clean p/s fluid and start the car. Keep filling the reservoir as the pump pushes it out into the container. When clean fluid comes out into your dirty fluid container have someone turn the wheel left to right slowly a few times while you keep adding fluid. Try not to let the pump run dry as you can damage or shorten the life of the pump. Once you're satisfied with the fluid color then you're done. Reconnect the return line and put the lid back on with the correct fluid level in reservoir and turn the wheel fully from side to side a few times to make sure the air is bled out. This flush may take 2 -3 qts depending on contaminants in the system and capacity of system. Get rid of the old oil properly (most garages & automotive suppliers will take it). If in doubt get a professional repair person to do it for you (it's not that expensive). You may want to add a power steering fluid conditioner (eg: Lucas) when you're done.

How often should you get an induction service and evap system flush and power steering flush?

Your post particularily interests me.

First some general info: Throttle plate cleaning and air induction service seems to be needed about every 18,000 miles, in my experience.

You can check your power steering fluid yourself and decide. Pull the dipstick out and wipe it on something white. If it's clear, you're okay, if it's discolored (brownish usually but translucent), then get it flushed.

I am really curious to know about the EVAP Flush. I have never heard of it. Maybe there is something new that I'm not familiar with, but would be surprised as we are usually close to the cutting edge. Plese get more info about this, as I am at a loss.

What can cause a persistent squealing when driving?

This is when you test the shop's trust and credibility that you took your car to.

Take it back and explain the problem as to how the symptoms changed. I would expect that they should try to immediately or asap get you car in and look over their work. Don't address them in a negative or hostile way, they should want to resolve this without stress on your or their parts.

Keep this in mind, these particular cars are more apt to squeak than many, but with enough attention the shop should be able to fix it.

There is a TSB on these brakes, it is #98-5A-19. this may help the shop if they have no answers.

AnswerThe squeeling is most likely a belt slipping. You can probably find a belt dressing at an auto parts store to spray on it. If the squeeling stops after spraying, replace or tighten the belt. Another cause may be that your neighbors cat is caught somewhere near the fan and the squeeling is actually the cat screaming as you are shaving his skin off, layer by layer. AnswerI agrre with the last guy, except about the cat. If it was the cat, it would also happen at idle.

Knowing what kind of car and engine size may help. However if you turn the wheel all the way at idle, do you hear this noise? You may or may not be able to tighten the belt. It may be controlled by a tensioner.

Do yourself a favor, find an independent repair shop you can trust. It always costs an arm and a leg (or seems to).
