My steering power is kind of weak...
 

I mean, it is hard to turn the steering wheel. Mine is a 02 model. It was not like this. The first time I noted this was when I was driving it, and it suddenly lost a lot of the steering power. I checked the fluid and the tension of belts. Both seem to be okay. I went to some auto service, they did what I did and didn't find any clue. Any suggestion?My steering power is kind of weak...

is it cold outside? on my genesis it was about -32c that day and it was hard as hell to move the steering wheel, or your power steering pump might be going
