• Q: How to replace the power steering pump on 2004 Chevrolet Aveo?

  A: The process of changing the Power Steering Pump starts with unfastening the air cleaner housing by removing its bolts and releasing the clamp. The first step is to detach the pump Drive Belt from the pulley through auto-tensioner adjustments. Drain power steering fluid while disconnecting pressure and supply lines from the pump and remove its pulley bolt and pulley. You can remove the pump assembly through the process of releasing the steering pump retaining bolts. Start the installation by fastening the pump using steering pump retaining bolts which should be torques to 25 nm (18 ft. Lbs.). Attach pressure and supply lines to the Power Steering Pump before you install the Power Steering Pump pulley and its bolt and tighten them to 25 nm (18 ft. Lbs.). Reinstall the air cleaning housing by tightening its housing bolts to 12 nm (106 inch lbs.) while using the clamp. A power steering fluid meeting gm spec. No. 9985010 or an equivalent should be used for all fluid additions or complete changes along with cold-climate fluid which gm dealerships can provide. Using appropriate power steering fluid remains vital to stop hose and seal damage and fluid leaks and pump termination. The process requires adding fresh fluid to the pump while bleeding air from the system followed by leakage inspection with needed correction of leaks before performing another bleed procedure.
