Noise

This is to Hyundai tech, How often do you run across Hyundai's that have power steering pump noise due to reservoir screen plugging ? There is a TSB
about this, 80-ST-001 When I had my timing belt done my 04 Santa Fe. it ran smooth and quite, after I got it back It had a whining sound. I took it back to the dealer and they told me that there was a leak in a power steering hose and it was low on power steering fluid causing it to whine and there must have been some damage to the pump because it still whined after repair and flush. I cannot accept that there was a leak, because it is not a daily driver and there was not any fluid stains where it was parked and the noise started right after the belt was done ! Since then I ran across several post online about the same problem after a timing belt change and have ran across several models of Hyundai's (some that don't have timing belts) on the road that are emitting the same irritating whining sounds !

I see one maybe every several months or so. Investigate the screen issue first. Can't remember the last time I had to replace a Hyundai pump for a noise issue. Hyundai released this bulletin for two primary reasons: to assist in correctly repairing vehicles, and to stop paying for power steering pumps that weren't defective.
We had an Elantra at our shop do this after another technician replaced the timing belt. Emptied reservoir and found screen clogged with junk. I think the reason this happens after timing belt replacement is that some technicians find it easier to take a hose loose and move the reservoir out of the way. If there's a large amount of contaminants in the pump, they now make their way to the screen as th fluid drains out of the reservoir.

Thanks, I will most likely get a new reservoir to see if that will clear up the problem. I can get a new reservoir on line for half of what the local dealer wants. The owners manual calls for psf-3 fluid, I understand it was a Hyundai proprietary designation and it is not used anymore. What should be used. If Dextron, #2 or 3 ?
Thanks, Striker

This is a update on this problem. I replaced the reservoir and topped off the fluid level, actually the whine was louder until the air was bled out then it went back to the level of whine that was there before.The screen in the reservoir was dirty and amount of fluid turbulence in the reservoir was no where near what is in the new reservoir, that tells me that the screen was partially plugged up. Looks like a new power steering is in my future !
