Power Steering Whine fix

A lot of you new members are probably experiencing a power steering whine in cold temps < 60F, which goes away as the engine compartment gets warm. The culprit is the o-ring on the PS pump inlet pipe. The o-ring has become glazed & lost it's original elasticity so it's contracting more than spec and allowing air to enter the pump when the temps drop. The fix is simple, replace the o-ring. For you guys who are a bit timid mechanically.. here's a simple DIY to guide you. I had a video but I couldn't find the original file. Although this should be very straightforward. Enjoy.

Tools Needed:

10mm wrench
shop towels / paper towels

Parts Needed:

New O-ring P/N: 91345-RDA-A01 (orange)

Part 1

Part 2

Part 3

Part 4

Part 5

If I left anything out, feel free to add it. I changed the PS with new Honda PSF. I might be switching up to Redline Syn PSF since it's been almost a year since the change, let me know if you guys want a DIY on it.

Thanks for posting up the TSB hata

The torque on the ps inlet bolt is only 8 lb.ft! That's almost finger tight so don't torque it down very much. Inacc the red ballons are from MS Word. Just change the fill color & transparency. I also forgot to include to rub a little ps fluid on the new o-ring.. I was conflicted with my junk ps fluid but I did so anyways. If you don't have fresh ps fluid around you can dip your pinky in the res & just smear a coat around the new o-ring before replacing the inlet tube.
