1997 chevy silverado k1500 Z71 4x4 Changed out power steering pump, the high pressure hose, return hose, gear box, and flushed and bleed the steering pump and I still have very little to no power steering any advise would help

power steering hoses run from pump to the steering box, (high pressure) and from the steering box to pump (low side).. is a closed connection. pump to box, then from box back to pump. High pressure should have pressed on fittings, while low side may have normal water hose clamps or replaceable hose without pressed on fittings.

I just finished replacing mine.

It is much easier if you do these steps:

1. Remove the serpentine belt.
2. Remove the nuts holding the main fuse box over the battery.
3. Remove the reinforcing bar over the battery.
4. Remove the battery.
5. Remove the windsheild washer tank.
6. Now you have access to remove the pump pulley. Without removing the stuff, it may be possible, but it will be extremely difficult.
7. Remove the pump pulley.
8. Loosen the high pressure hose fitting.
9. Remove the return line clamp.
10. Remove the power steering pump mounting bolts.
11. Remove the high pressure hose fitting.
12. Remove the power steering pump while sliding off the low pressure hose.
13. Remove the clips holding the reservoir on the pump.
14. Remove the reservoir.
15. Install new o-ring on the reservoir.
16. Install reservoir on new pump.
17. Install clips to hold reservoir on pump.
18. Install new o-ring on high pressure fitting.
19. Place new pump in position while sliding on low pressure hose.
20. Loosely attache high pressure fitting.
21. Tighten pump to mounts.
22. Tighten high pressure fitting.
23. Install clamp on low pressure hose.
24. Install power steering pulley.
25. Install washer reservoir.
26. Install battery.
27. Install reinforcing cross member.
28. Install fuse panel.
29. Install serpentine belt.
30. Bleed the power steering system.

11. Remove the high pressure hose fitting.
12. Remove the power steering pump while sliding off the low pressure hose.
13. Remove the clips holding the reservoir on the pump.
14. Remove the reservoir.
15. Install new o-ring on the reservoir.
16. Install reservoir on new pump.
17. Install clips to hold reservoir on pump.
18. Install new o-ring on high pressure fitting.
19. Place new pump in position while sliding on low pressure hose.
20. Loosely attache high pressure fitting.
21. Tighten pump to mounts.
22. Tighten high pressure fitting.
23. Install clamp on low pressure hose.
24. Install power steering pulley.
25. Install washer reservoir.
26. Install battery.
27. Install reinforcing cross member.
28. Install fuse panel.
29. Install serpentine belt.
30. Bleed the power steering system.

Leave the return line disconnected from the pump and run into a bucket. fill new pump and start engine have some one keep adding fluid until clean fluid is going into bucket. Caution make sure to secure hose to bucket or you will make a mess. Also turning the steering wheel about a half turn in each direction Will help it to flush out the gear box better.

Very simple and no special tools. Take your time and put some rags or a oil pan underneath it and wrench away!

Please don't forget to rate!!!!

disconnect the return line at pump put it in a jug start the engine check for cirrulation and too bleed air keep filling pump if you have no cirrulation the reconnect the return hose and discnect the supply too see if it pumping if it is then you have a blockageif not then you may have a bad pump

The high pressure and low pressure hoses are different sizes at the gear box. And the low pressure /return hose is usually rubber with a clamp at the back off the pump.

You're going to have to bleed the system alot on those trucks. Just remove the return line and have an assistant turn the steering wheel back and forth just enough to engage the pump and filling the resevour while doing this. Keep bleeding until you have a good flow of P/S fluid out with no air bubbles. This can take a while.
