I replaced the steering pump on this car with around 100,000 miles hoping that this was the issue with the squeal I heard, usually only from a cold start. The squeal goes away after the car warms up. Once the car is warmed up the squeal only happens when I turn the wheel all the way to the left or right. I am not sure how to get air out of the system if that could be the problem? I turned the steering wheel left to right all the way many times hoping this was the method to get air out? I put in new Aisin pump. I have new belts on as well and they are tight. Any thoughts? Thanks
Have your battery + alternator load tested.
Could you explain what the load test would indicate? It seems to me that this has something to do with the pump(which is new) the belt(which is new) and maybe the rack and pinion? The belt does not have a tensioner so I made it as tight as I could with a pry bar. I am not sure about air in the system( how to get it out if it is in there? Thanks
You said it squeals when cold. This is when the alternator is working the hardest (after you just used a bunch of juice to start the engine) which puts resistance on the belt. A failing battery or alternator will can bog down all the other accessories and make the belt taught.
The PS pump is just the one complaining.
You're not supposed to make the belt "as tight as you can". That's too much.
if you turned your steering left and right , lock to lock, a few times, then the air should be gone. But air wouldn't cause squealing anyway. Maybe a groan.
The car is 17 years old - how old are your fan belt and tensioner? Power steering puts additional load on the belt and can cause slippage if worn or too loose, resulting in squealing.
he said the belt is new, but the tensioner would be something to look at
Ah, I missed that, but certainly if the tensioner is weak that could cause the problem.
The belt does not have a tensioner so I made it as tight as I could with a pry bar.
OK, so Hyundai was using a manual tension adjustment on that vehicle. There will be a factory specification for the amount of tension to put on the belt that can be checked with a suitable gauge. (I use a belt tension gauge on my '99 Jeep Cherokee which has a manual tension adjustment.)
If you don't have the specification or a belt tension gauge there is a simple way to approximate the appropriate tension on serpentine belts. The rule of thumb is to be able to twist the belt on its longest run with a finger and thumb 90 degrees while feeling resistance. If you can turn it more than 90 degrees there is too little tension. If you cannot turn it that much there is too much tension. Also the belt will stretch after initial installation and running of the engine and tension needs to be rechecked.

After replacing the pump it is likely that there is air in the system if you have not bled it. There are plenty of instructional videos showing you how to bleed air out of the power steering, such as these that took about 10 seconds to find with a quick web search:
