Help With P/steering

[andrewm1]

Hi i think i need to change my PS Fluid as it looks dirty and the car screeches @ full lock , i have looked @ the Haynes book but it doesn't give much detail.

Does it need bleeding? if so where and how?

Another point is that apart from screeching at full lock (and occasionally sometimes screeching while normal turning ) the rev's drop when this happens, The belt is tight so i am thinking maybe a new pump?? if the new fluid makes no difference

Any advice guys thanks
