Power steering pump replacement instructions please?

Hi Jenny and thanks for using 2CarPros. Com. If you are purchasing a rebuilt unit, the company may be having issues. As far as install, I have attached the directions specific to your vehicle. Also, there are two different engines available for you vehicle so I will attach pictures of both. Read through the directions and make sure you are not missing a step. If you are not, I would try a different brand pump.

The first set of directions are for the 2.0L Turbo, as well as the first three pictures.

Hi again. Honestly, other than a bad pump, I cannot see what would make it lock up unless when you reinstall the pulley on the new pump, you are hitting it with a hammer or putting it on too far. Here are specific directions related to the belt pulley install. Scan through them and let me know. These directions are specific to the new model you provided. Again, I can not over stress the need to avoid jarring the shaft. It can break or become bent and damaged very easily.

BELT PULLEY ON POWER STEERING PUMP
Belt Pulley On Power Steering Pump

To Remove
Detach the intake hose with mass air flow sensor and turn it to one side.
Use 83 95 254 Drawbar handle, hydraulic belt tensioner to relieve the strain on the belt tensioner and remove the belt.
Using 89 96 423 Puller, servo pump pulley, remove the pulley.
To Fit
Fit the new belt pulley on the shaft, using fitting tool 89 96 415.
The belt pulley should be fitted so that its hub is 3.0 mm beyond the edge of the pump shaft.
IMPORTANT: No load should be placed on the pump shaft. Do not pull the belt pulley too far in.
Use 83 95 254 Drawbar handle, hydraulic belt tensioner to relieve the strain on the belt tensioner and fit the belt. Check that the belt is correctly fitted on all pulleys.
Connect the intake hose with mass air flow sensor.

Drive the car on test to check pump performance and see if any leakage occurs.

Let me know your thoughts.

Take care,
Joe

It sounds more like the problem is not in the pump. If it is blowing off pressure lines and then failing it sounds like the problem is in the steering rack itself. Either the valving is damaged or there is debris that is blocking flow. If the hoses failed due to age it is possible that some of the internal lining went into the lines and the steering itself. If it has a steering cooler it may also be partially blocked causing high pressure to damage the pump.
