Pressure Hose O-Ring

You must start replacing a Power Steering Reservoir by draining fluid from its compartment. Use a hose clamp tool to release the clamp on both fluid hoses followed by their removal. Lastly install plugs into the hose openings to protect the power steering system from contaminants. Detach the reservoir attaching bolts and then remove the reservoir from the vehicle. The Power Steering Reservoir installation requires you to use the attaching bolts according to a torque of 7 n.m (62 lb in). Typically you should link both hoses to the system and finalize the hose clamps. The gm spec. No. 9985010 and equivalent power steering fluid together with cold climate fluid options exist at gm dealerships to use for fluid addition and complete replacements. A power steering system failure can occur when replacing the fluid with an improper product thus harming the hose and seals and causing leaks while putting the pump at risk of failure. Check the Power Steering Reservoir while filling it with the correct fluid and search for any fluid leakage. The system requires bleeding when leaks are detected so immediate action should be taken to identify the source before starting the bleeding procedure.

Loosen the hose clamps, remove both hoses, then take out the fluid reservoir attaching bolts and remove the reservoir.

Attach the fluid reservoir using the power steering fluid reservoir attaching bolts and tighten them to 7 Nm (62 inch lbs.). Connect both hoses and secure the hose clamps.

Remove the fluid reservoir attaching bolts and take out the fluid reservoir.

Using the incorrect fluid can lead to damage of the power steering hose and seals, fluid leaks, and pump failure.
