Replacement involves removing the hoses then bolts and bolting the new one in and attaching hoses then filling with fluid.
If reservoir replacement does not resolve the next step would be to replace the pump. I'll post info on that below.
1. Loosen the bolt fixing the wiring bracket, and then move the wiring side-ward.
2. Remove the pressure hose (A) from the oil pump (B), and then disconnect the suction hose (C) from the suction connector and drain the fluid into a container.
3. Loosen the tension adjusting bolt (A) on the power steering "V" belt.
4. Remove the "V" belt (A) from the power steering oil pump pulley.
5. Loosen the power steering oil pump mounting bolt and the tension adjusting bolt, and then remove the steering oil pump assembly (A).
6. Remove the power steering oil pump mounting bracket (A).
