Hi and thanks in advance for any help. So I have 2001 Silverado 1500 and my serpentine belt and power steering pump and high pressure line all needed to be replaced because leaking power steering fluid everywhere and impossible to steer. Now keep in mind I'm a girl and Don't know much about cars but I'm learning, I probably didn't need all those parts replaced since I still have same problem. It looks like it's coming from beneath belt where shaft of pulley is? Could it be a connection o ring or clamp or something? I'm stumped. Thanks

 

Sometimes pictures would help. Take pictures and post them here. Perhaps get a can of engine cleaner and clean off the fluid if you can't tell where the leaks are from.
You can clean off the serpentine belt with engine cleaner too. No need to replace.
Fill the reservoir with new fluid. Start the car and steer the wheels to look for source of the leak. Some brands have different color than your current fluid and that might help detect the problem.

 

Who replaced the pump and the high pressure line? Did they diagnose the problem? If so then they need to fix the leak for you. If they did everything correctly and the new parts are good, then the only other thing it could be is the return line.

 

If the pump was replaced was it with the reservoir attached or did you just replace the pump and have to move the reservoir?
