1. Preparation:
* Safety First: Disconnect the negative battery cable. This prevents accidental short circuits.
* Gather Tools: You'll need various wrenches (metric), sockets, a power steering pump pulley puller (highly recommended), a drain pan, rags, and potentially a pry bar. New power steering fluid.
* Jack and Support: Securely jack up the car and support it on jack stands. Never work under a car supported only by a jack.
2. Accessing the Pump:
* Locate the Pump: The power steering pump is typically located on the front of the engine, driven by a belt. Consult a repair manual specific to your 2000 Grand Prix GT for the exact location and components.
* Remove Related Components: This might involve removing the serpentine belt, possibly the alternator, and other components obstructing access to the pump. A repair manual will detail the specific order and procedure.
3. Removing the Pump:
* Disconnect Fluid Lines: Carefully disconnect the high-pressure and low-pressure power steering lines. Have a catch pan ready as some fluid will likely spill. Note which line goes where.
* Remove Pulley: Use the pulley puller to remove the pulley from the pump. This is crucial; trying to pry it off can damage the pump.
* Loosen Mounting Bolts: Carefully remove the bolts holding the pump to the engine block. They can be stubborn due to corrosion.
* Remove the Pump: Once the bolts are removed, gently remove the power steering pump.
4. Installation:
* Install New Pump: Install the new power steering pump, ensuring the pulley and its bolt are properly secured.
* Reconnect Fluid Lines: Reconnect the high-pressure and low-pressure lines, ensuring a tight seal.
* Reinstall Components: Reinstall the components you removed earlier (pulley, alternator, etc.).
* Replace Serpentine Belt: Reinstall the serpentine belt.
* Add Power Steering Fluid: Add new power steering fluid to the reservoir, checking the level frequently during the process, and following the instructions in your manual.
* Bleed the System (Important): Start the engine and turn the steering wheel lock-to-lock several times to bleed any air from the system. Check for leaks. Top off the power steering fluid as needed.
5. Final Checks:
* Check Fluid Level: Ensure the power steering fluid level is correct.
* Check for Leaks: Inspect for any fluid leaks around the pump and connections.
* Test Drive: Test drive the car, checking the power steering operation.
Strongly Recommended:
* Repair Manual: Obtain a repair manual specific to your 2000 Pontiac Grand Prix GT. This will provide detailed diagrams and instructions, saving you time and preventing potential damage. Haynes and Chilton are reputable publishers.
* Torque Wrench: Use a torque wrench to tighten bolts to the manufacturer's specifications to prevent damage.
This job can be challenging for beginners. If you lack mechanical experience, consider taking your car to a qualified mechanic. The cost of a repair will likely be less than the cost of damaging something during the process.
