Hi everyone, I just replaced the 2 power steering pressure lines to fix an age old leak that has been driving me crazy for years. After I put the new lines on I filled the P/S fluid, started the car and the power steering pump locked up on me after about 10sec. The belt was just slipping on the pulley. Anyways, I shut the car down and took the belt off only to find that the pump now spun freely. So I reassembled everything and tried again-same result. After taking the belt off this time I found that the pump would not turn, but it didn't seem like it was siezed, almost felt like it was building pressure until I couldn't spin it anymore. I turned the pump a fraction of a revolution backwards and then it spun freely again. Let me restate that the only symtom that I was trying to fix was a very minor seepage. What do you guys think? Thanks for any, and all input.
Power Steering/Hydroboost problem?

First, none of the connections are crossed right.
Then try putting your old hoses back on one at a time and see how it works. This will help narrow down where your problem lies. Sounds like you have a blockage to me too and the pressure building up is stopping the pump.

Perhaps you could help me verify the proper hose routing to double check my work? The pressure line leaves the pump and goes to the fitting on the passenger side of the hydroboost unit. The other line exits from the driver side of the hydroboost unit and enters the steering gear on the right hand side and slightly infront of the return. I hope I explained that well. Thanks.
It sounds right but here is a crude drawing of the hose routing.
If you are hydrostatically locking up the pump due to a blockage then you will have a excessive build up of pressure before any blockage. Then by relieveing the pressure you should be able to turn the pump again.
Then try this out.
Allow the pump to lock up and verify you cannot turn it by hand. Then loosen up the return fitting at the pump and see if the pressure bleeds down and if you can then turn the pump by hand. If not tighten it back up and work backwards to the next fitting. Keep repeating this for every fitting until you bleed the pressure off and are able to turn the pump. Then you will know between what two connections your blockage is.
