I replaced the power steering pump but the new one pours fluid out of the back when I start the engine.

Hi,

There really aren't too many places for it to leak from. Are both the high-pressure and low-pressure hoses tight and in good condition? Also, I believe there is a cooler on this vehicle for the power steering. Are there any leaks in that area that could appear to come from the pump?

Let me know.

I bought slightly thicker o rings, and it fixed the problem. The leak was where the high pressure line connects to the pump.

Hi,

Thanks for the update. I'm glad to know you got it resolved. I had a feeling it was the high-pressure line, but anything is possible.

Take care and feel free to come back anytime in the future.
