My power steering pump started the whine a few months ago immediately after replacing the timing belt and all including a new accessory belt. I just replaced the o-rings this weekend and darn if it didn't reduce the noise. Really, it's only loud when I first start up the car and goes away after a while, but still. I'm certain its the PSP. Just curious if these pumps die slowly or if they go fast? And if'n'when it needs replaced is OE recommended or would a RockAuto.Com pump (Cardone) be sufficient? Probably want to flush the fluid before replacing if I go that far and if so should I stick with Honda PSP fluid? Tnanks.
