I have a 4BD1-T, and i'm having trouble with my power steering pump. I took it off and disassembled it, but everything inside looks good. When I connect the lines and run the engine, however, there is just a small stream of aerated p/s fluid that exits the output slowly, nothing else.

I want to say that the p/s fluid is bypassing the pump somehow and just trickling out due to gravity. Is this possible? Can anyone help?

I think mine will pass fluid when it's not running. But clean fluid, aerated may mean the supply is blocked.

Which way do you have your inlet and outlets connected?

Sucking air from somewhere. Possibly from hose connections.

Some pumps can take a bit more to properly bleed, so it could be cavitation in the pump because all the air hasn't been purged?

That's what it was. I had to force fluid into the pump with a little pressure (it wouldn't go in just with gravity).

Good thing too, I just drove it 250 miles!

Thanks guys.
