Power steering pump replacement running dry and overflowing
2007 Ford Taurus:
Just replaced the power steering pump with a
brand new one. I didn't bleed or replace the fluid
before hand just drained what was in the reservoir
and threw in the new one.
After turning the wheel both ways without the key
in I thought I had enough fluid in. When I started
the car the fluid immediately ran dry and I could
see inside the pump. I added fluid quickly but it still
didnt seem like enough so I stopped the car. This
is when the new fluid and the old fluid mixed
together and bubbled over out of the reservoir. I
dont know what's happening? Do I have to bleed
the system and start with all new fluid? Any
explanation would be great thanks!
The proper way to fill the system is to fill to the cold level, then start the car. Add if the level goes down. Then have someone turn the wheels lock to lock a few times while the engine is on and car is in park while you are adding fluid. Let the level normalize and turn off the car allowing the air in the system to bubble out. Maybe 30mins. From your description, you overfilled the system. Pump out the old fluid and start over again.
