Tools You'll Likely Need:
* Repair Manual: Absolutely essential for specific torque specs and procedures.
* Wrench Set: Metric and possibly SAE, depending on your Corvette.
* Socket Set: Metric and possibly SAE, with extensions and a ratchet.
* Power Steering Pump Pulley Wrench: This specialized tool makes removing the pulley much easier.
* Fluid Catch Pan: To collect the power steering fluid.
* New Power Steering Pump: Ensure you get the correct pump for your engine.
* New Power Steering Fluid: Use the type recommended in your repair manual.
* Jack and Jack Stands: To safely lift and support the vehicle.
* Wheel Chocks: For added safety.
* Torque Wrench: Crucial for tightening bolts to the proper specifications.
* Gloves: Protect your hands.
* Safety Glasses: Protect your eyes.
General Steps (Consult your repair manual for precise details):
1. Safety First: Disconnect the negative battery terminal. Raise the vehicle safely using jack stands and secure wheel chocks.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a catch pan.
3. Access the Pump: The location of the power steering pump varies slightly depending on the engine (small block or big block). You'll likely need to remove some components to gain access, such as belts, pulleys, and potentially other ancillary components. Your repair manual will guide you through this.
4. Remove the Power Steering Pump Pulley: This is often the most challenging part. Use the specialized pulley wrench to prevent damage to the pulley or pump.
5. Disconnect the Power Steering Lines: Carefully disconnect the high-pressure and low-pressure lines from the pump. Have rags ready to soak up any remaining fluid. Note the orientation and routing of the lines for reassembly. Some lines may require special tools for removal/installation.
6. Remove the Pump Mounting Bolts: Carefully remove the bolts securing the pump to the engine block.
7. Remove the Old Pump: Carefully remove the old power steering pump.
8. Install the New Pump: Install the new power steering pump, ensuring it's seated correctly. Tighten the mounting bolts to the specifications in your repair manual using a torque wrench.
9. Reconnect the Power Steering Lines: Carefully reconnect the power steering lines, ensuring they are securely attached.
10. Install the Pulley: Reinstall the power steering pump pulley, again using the correct tool and tightening to the specified torque.
11. Reinstall Belts and Components: Reinstall any components you removed to access the pump.
12. Refill the Power Steering Fluid: Add the correct type and amount of power steering fluid as specified in your repair manual.
13. Bleed the System (if necessary): Your repair manual will explain if and how to bleed the power steering system. This is important to remove any air bubbles.
14. Test: Lower the vehicle, reconnect the battery, and test the power steering system. Check for leaks and ensure the steering operates smoothly.
Important Considerations:
* Fluid Type: Use the correct power steering fluid. Using the wrong fluid can damage the pump and system.
* Torque Specifications: Use a torque wrench and adhere to the manufacturer's specified torque values for all bolts. Over-tightening can cause damage.
* Repair Manual: This is not a comprehensive guide. A repair manual specific to your 1979 Corvette is essential.
* Professional Assistance: If you're not comfortable performing this repair yourself, consider taking your Corvette to a qualified mechanic.
This task is complex and involves working with pressurized systems and potentially hazardous fluids. If you're unsure about any step, seek professional help. Improper repair can lead to serious damage or injury.
