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 !
