Tools You'll Likely Need:
* Wrench Set: Metric sockets and wrenches, including a socket that fits the power steering pump pulley bolt. This will likely be a large bolt requiring a breaker bar or ratchet with extension.
* Drain Pan: To catch power steering fluid.
* Socket Wrench and Ratchet: For loosening and tightening bolts.
* Power Steering Fluid: To refill the system after the repair.
* Gloves: To protect your hands from power steering fluid.
* Shop Rags: To clean up spills.
* Torque Wrench: For tightening bolts to the correct specification (crucial to avoid leaks and damage).
* Pry Bar (possibly): May be needed to help separate the pump from the mounting bracket.
* New Pump Gaskets/Seals (highly recommended): Replacing these prevents future leaks.
Procedure (General Steps - Refer to a Repair Manual for Specific Details):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental electrical shorts.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a drain pan.
3. Disconnect Lines: Carefully disconnect the high-pressure and low-pressure power steering hoses from the pump. Have rags ready to absorb any spilled fluid. You may need to loosen clamps with pliers or a special hose clamp tool. Note the orientation of the hoses to ensure correct reassembly. Take pictures if you're unsure.
4. Remove the Pulley (if necessary): Some models require pulley removal before pump removal. This usually involves removing a large bolt in the center of the pulley. You may need a pulley puller for stubborn pulleys.
5. Remove Mounting Bolts: Locate the bolts securing the power steering pump to the engine block or bracket. Unscrew these bolts, using the appropriate socket and wrench.
6. Remove the Pump: Gently wiggle and pull the pump free from its mounting location. There may be some resistance due to the gasket seal. A pry bar (used carefully) might be necessary, but avoid damaging the pump or the engine block.
7. Install New Pump: Install the new pump (including new gaskets/seals) in the reverse order of removal. Make sure everything lines up correctly and that all gaskets are in place.
8. Reconnect Hoses: Carefully reconnect the high-pressure and low-pressure hoses, ensuring they are properly seated and the clamps are tightened securely.
9. Reconnect Pulley (if necessary): Reinstall the pulley if you removed it earlier. Tighten the pulley bolt to the proper torque specification.
10. Refill Power Steering Fluid: Add the correct type and amount of power steering fluid to the reservoir.
11. Bleed the System (possibly): Some repair manuals may recommend bleeding the power steering system to remove air bubbles. This usually involves turning the steering wheel lock-to-lock several times while checking the fluid level.
12. Reconnect Battery Terminal: Reconnect the negative battery terminal.
13. Test: Start the engine and check for leaks. Turn the steering wheel lock-to-lock to ensure proper operation. Top off the fluid level as needed.
Important Considerations:
* Repair Manual: This is absolutely crucial. A Haynes or Chilton manual specific to your 1997 Chevy Venture will provide detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle.
* Safety: Wear safety glasses, work in a well-ventilated area, and handle power steering fluid carefully. It's harmful to the skin and eyes.
* Professional Help: If you're not comfortable performing this repair yourself, take your Venture to a qualified mechanic.
This is a general guide. The specific steps and tools may vary slightly depending on your exact vehicle configuration. Always refer to a repair manual for your specific model before starting the repair.
