REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Remove the hoses at the pump, and tape the ends to prevent dirt from entering.
- Plug the pump fittings to keep the fluid in the pump.
- Loosen the bracket retaining nuts and remove the drive belt.
- Withdraw the bracket-to-pump bolts and remove the pump from the car. On large block Corvettes, the alternator drive belt must be removed first.
- Place the pump on the bracket and install the attaching pieces hand-tight.
- Install the hoses and tighten the fittings.
- Refill the pump reservoir. Turn the pulley backward to bleed the pump.
- Install the belt over the pulley and tighten to the correct tension.
- Bleed the hydraulic system, as previously described.
BLEEDING POWER STEERING SYSTEMOFF.
- Run the engine until the power steering fluid reaches normal operating temperature, approximately 170°80° then shut engine Remove the reservoir filler cap and check oil level.
- If the oil level is low, add power steering fluid to the proper level and replace the filler cap. When adding or making a complete fluid change, always use GM #1050017 or equivalent power steering fluid. Do not use transmission fluid.
- When checking the fluid level after the steering system has been serviced, air must be bled from the system. With wheels turned all the way to the left, add power steering fluid to the proper level indicated on reservoir.
- Start the engine, and running at fast idle, recheck the fluid level. Add fluid if necessary.
- Bleed system by turning wheels from side to side without hitting stops. Maintain fluid level just above internal pump casting. Fluid with air in it will have a light tan or milky appearance. This air must be eliminated from fluid before normal steering action can be obtained.
- Return wheels to center position and continue to run engine for two or three minutes, then shut engine off.
- Road-test vehicle to make sure steering functions normally and is free from noise.
- Recheck fluid level as described in steps 1 and 2.
