All of a sudden-car hard to steer--what might it be?

My 03 Acura had a power steering belt replaced recently, yet when I drove it today the car was very hard to steer–as if the power steering were operating at about 50%. Driveable, but barely.



What might it be? how should I diagnose?



Thanks in advance

Check to see if the belt tension is still good. I’ve had new belts loosen up shortly after being installed.

Might not hurt to check the fluid level.
