* Accessibility: The pump is located in the engine bay, and while not completely buried, it's not easily accessible. You'll likely need to remove or loosen various components for better access, such as belts, pulleys, and potentially hoses.
* Fluid Management: Power steering fluid is messy. You'll need to drain the system properly before disconnecting hoses to avoid a significant fluid spill. Also, you'll need to refill and bleed the system afterwards.
* Belt Tensioner: You'll likely need to deal with a belt tensioner to remove the drive belt, which can be challenging if you're not familiar with the procedure. This often involves special tools.
* Hoses and Fittings: Disconnect and reconnect hoses carefully. They can be stiff and brittle after years of use. Damage to the hoses or fittings can lead to leaks.
* Torque Specifications: Properly tightening bolts and nuts to the manufacturer's specified torque is essential to prevent leaks and damage. You'll need a torque wrench.
* Bleeding the System: After installation, you'll need to bleed the air from the power steering system to ensure proper operation. This typically involves turning the steering wheel lock-to-lock with the engine running.
In short: If you have some experience working on cars, possess basic tools including a torque wrench, and are comfortable with following detailed instructions (like those in a repair manual), you can probably tackle this job. However, if you lack experience, it's best to take it to a mechanic. The cost of a professional repair will likely be less than the cost of parts and time spent troubleshooting if something goes wrong during a DIY attempt. A repair manual specific to your year Grand Prix GTP will be invaluable.
