I have a 04 6-SPD TL with 72K miles, only thing major was the egr valve suprisingly.. now after taken it to a mechanic i found that the belt is getting kinda loose making the power steering vibrate therefore causing the nose and gets louder when i rev it or when the belt moves faster. I also see a little leak on the house where the power steering pump is. Please advise of what I need to do in terms of general tune up parts that you guys would recommend me to use @ about 75K.

Thanks in advance.
