HI I GOT AN HYUNDAI ELANTRA YEAR 2001 2LITRES,HAVE APROBLEM WITH MY POWER STEERING IT DOESN'T WORK AT ALL ,IT GOT FULL OF FLUID NO LEAK,I HAVE PRESSURE FROM THE POWER STEERING PUMP,SO I CHANGE THE STEERING RACK,NOTHINGS HAVE BEEN CHANGE THE STEERING IS STILL HARD

If it's leaking fluid and air is getting into the system, that would cause the symptoms you're talking about. Get it checked out

Check the power steering fluid

Either the hose connections are leaking at the rack or the rack is leaking. If you're not seeing any fluid, disconnect one of the bellows at the end of the rack. I bet fluid will pour out

figure out where it is leaking from and replace that part/hose or pump or rack

your power steering pump has a cap on it.you have cold mark and hot mark.when car is cold engine not running.when you remove power steering cap it should be on cold mark.if not add until you get to cold mark on cap stick..dont over fill or you blow the seal.now when engine is hot been running.turn off car check.power steering cap should read full hot.mean level is correct.when you first check power steering fluid and it was real real low.you got a leaking high pressure hose.or power steering pump seal is leaking.if all check out good.your problem could be low tire pressure.worn ball joints.and tie rod ends.rack and pinion steering gear binding.

have your power steering fluid checked it sounds low.new belts may have put strain on power steering pump.

This is easy to fix. Go to your local autoparts store and tell the year model & motor size. They will give you the proper hose to replace it with, plus ask for the fluid that you will need to pour into the pump tank. Two fitting to take off, & reinstall. Top off fluid level, then crank motor, and turn steering wheel from right to left a few times. Sometimes you might have to do the turning alot to get the air back out of the lines. Later on check fluid again, and top off if needed. I know some autoparts stores will help you in the parking lot?????

I have had this issue but it was resolved by power steering fluid.

If it's not a serpetine belt, max deflection of 3/4" on longest segment should be safe,  don't make alternator belt tight as a drum or you will burn out alternator bearings quickly.  If it has serpentine belt, the spring tensioner should keep the belt properly tensioned unless it's worn out.
It only needs to be tight enough to not slip, too loose will squeal and you will have to tighten,  to tight will kill alternator and you will spend $$.

Check and make sure that your power steering fluid is topped off. Could possibly problems with your power steering pump. Mine does the same and the fluid is full. I just keep an eye/ear on it. If it continues to get worse than it could be the pump going out. If the fluid is allowed to get too low, it could possibly get air in it affecting both the "feel" of the steering and making a noise.
