Power Steering fluid leaking from reservoir cap!?

Asked by Nov 02, 2016 at 05:42 PM about the 1999 INFINITI Q45 RWD

Question type: Maintenance & Repair

I took the cap off earlier today to check the levels because of a whining
sound when i turn. It was full so i put the cap back on and planned to get it
flushed first paycheck of this job i'm going to start next week. I started my
car to drive it around the house to my garage and it was leaking a lot from
under the cap. I put it on tight and even took it off and put it back on as
tight as possible. The cap seems to be in good shape. Could it be more
complex than just needing a new cap?? I NEED to be able to get to this job.
This is my only car and money is low. Things are dire.

This is caused by a bad power steering pump.

Remove power steering fluid from reservoir with a turkey baster or something equivalent then add some Lucas Power Steering Stop Leak to reservoir if it works as fast as it did with my power steering problem your problem will go away immediately.

If this happens during the winter or in cold conditions, it's more likely that the low psi/tire pressure is causing the whining noise. I have a 2003 Infiniti m45. When my PSI goes low during extremely cold weather (PSI goes down every day for some reason), i get hard steering, noises from the power steering pump once the car is started. When the car is turned off, power steering fluid starts oozing out of the reservoir (top) with bubbles. Put air in the tires and fill the reservoir up with Honda synthetic fluid. The problem will go away.
