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.
- 10mm wrench
- shop towels / paper towels
- New O-ring P/N: 91345-RDA-A01 (orange)
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.
