Hyundai Repair/squealing/squeaking noise from power steering pump
craig wrote at 2006-11-20 17:17:07
I have had several Hyundai cars over the past 14 years and I have found that Hyundai makes a pretty good car. But the dealers have very poorly trained mechanics. I won't be surprised if the mechanic at the dealer is damaging the new pump during installation. Try finding a certified ASP technician to work on your car.

I had the same squeaky power steering belt problem. I read your recommendation and tightened the alternator belt as you suggested and the problem went away. You're the man!!!

My 2005 Elantra is at the dealer right now for this problem. I had my trusted mechanic replace the belts at 45K miles, since it wasn't covered by warranty. After replacing the belts, the squeak won't go away. The dealer is probably replacing the power steering pump under warranty. If not, I'm going back to my mechanic to have the alternator belt tightened. A friend of mine said that, since we've already looked at the pullies on the power steering pump, it might also be that the shims need adjusted, which is a touchy business. To be continued...

Having gone through this recently, I found that the power steering was very sensitive to what fluid was used. I had work done, and they used an off the shelf all purpose power steering fluid. I had problems similar to what you have described. I eventually put Mercon III ATF fluid in, and that eliminated the problem for awhile, but it now appears that I have an issue with the hoses breaking down, since I have found small black rubber particles in the power steering reservoir. I have been told that the Hyundai requires the synthetic fluid, and the petroleum based may cause hose degradation. I have not confirmed that piece of information as of yet.

Different Hyundai vehicles require different power steering fluids. All U.S. models 2005 and older use Dexron/Mercon transmission fluid in the power steering system. On newer vehicles, it varies by model. Be sure to check the owner's manual for the proper power steering fluid.
Additionally, the incorrect fluid will typically not cause a squealing noise. That noise is characteristic of a loose belt. If there's a problem with the pump or fluid or a clogging of the reservoir screen, the system is most likely to exhibit a humming or whining noise.

I had the same problem; all they did was tighten the belts, and now the problem. have them do that you should be good.

The advice given here is perfect. I have been struggling with the exact same problem on a Hyundai Matrix. Various mechanics have not been able to solve my problems and have also replaced belts and pumps. Excellent advice and site. Well done

Thank you! I was have the same exact problem with my 2000 elantra and we tightened the alternator belt and now it is 100% GONE!!!! I am so glad to have it fixed. replaced the power steering pump and probably didn't even need to...

Why would the alternator belt - affect the power steering belt slipping? You have seen this problem go away with a alternator belt adjustment? Even though the power steering betl is the one slipping.

yeah id imagine a new belt would stretch a little bit and become loose till it breaks in, you should just have to have it re-tightened, I had the same problem with my car, power steering gets a bit tight while its squealing too

Yeap Alternator Belt ...My first tought was steering belt then I fix the tension on that one but the sound continue so went down and give some tension to the alternator belt and it works.
Noise Gone... Thanks Guys

Great feedback, love the posts. Same problem on a 2002 Elantra. I replaced the belts (alternator and power steering) and after about a month, it started squealing again. After tightening the power steering, I took it for a ride and it was still squealing. Came in, saw this post, tightened the alternator belt and the squeal went away. Thanks!

I have a 2002 Elantra. This car does not have the serpentine belt that you might be use to. The power steering pump and water pump are driven by the alternator belt. The alternator gets its drive directly from the crank pulley. When turning your wheels the power steering pump has a load placed on it to deliver more fluid to turn the wheels. If the alternator belt is loose, when the power steering pump needs the extra pressure to turn the car it wont be there because the alternate belt isn't giving the extra drive. When this happens the power steering belt will squeal or stop, making it look like a power steering problem.

Thanks, looked up how to replace the steering pump. Saw the alternator post. Saved about a hundred bucks. Thanks

I just tried the fix you explained here, by tightening my alternator belt, it solved my power steering belt slip and squeak. Thanks So MUCH!!

Thank you so much for this i was about to invest in a mechanic like crazy. the alternator was in fact the issue.
Tommy wrote at 2015-04-02 12:41:29
this is a common problem with power steering pumps with reservoirs separate from the pump there is a screen inside the reservoir that needs to be cleaned due to contaminated fluid ,it will cause low fluid to the return to the pump causing the belt to slip because the pump is stopping

Tightening the alternator belt fixed mine too. Thanks so much!

I tried changing the power steering belt, then the pump, then used spray on the belt all to no avail. I was desperate so I thought "what the heck I'll try anything even if it sounds crazy, which tightening the alternator belt sure does, and it worked!!! I even loosened the power wteering belt and still no noise! Thank you, thank you.

Over the past 40 years of auto repair I've noticed that serpentine belts need to be "tighter" than the "v belts" that so many of us are use to. After I install a serpentine belt I get the engine running temp hot and then re tighten the serpentine belt and have seen no problems with squeal. These belts can only be adjusted after they have gotten hot. Had to retighten other mechanics "job's" due to the "cold belt squeal". So, adjust twice and limit your return customer call's.

I changed the power steering fluid then the power steering reservoir, pump suction hose and pump hose. I then changed the steering pump. Squealing worsened after changing the pump. I saw that the alternator adjustment locking bolt was loose. I tightened the alternator belt and squealing is gone! Thank you.

the alternator belt pulley also drives the power steering belt so if the alt belt slips and sqeals the power steering pump does not work. On mine the batt. light would come on as well and thats how i figured it out. Drove me crazy for a while lol just tighten the alt belt.

Tightening the alternator belt fixed our issue too! Thanks a million!!!

Tried everything at first. I thought, what do I have to lose? Tightened the belt much more than I thought it should (been working on cars for 30 years as a hobby). Well, it worked. Thanks all!
