First introduced in the 1960s, the Grand Prix was manufactured by Pontiac until that company was dissolved in 2008. The 1997 Grand Prix was part of the fifth generation of the vehicle. The driver steering in these cars is assisted by the use of a hydraulic power steering system. This type of system utilizes fluid under pressure to help make turning the Grand Prix easier. A central pump circulates the steering fluid through hoses in the system. Because these hoses can sometimes crack, you may need to change the power steering hose on your Grand Prix.
Move the 1997 Grand Prix to an area where you can work, if it is safe to do so. You will need room to work around the front of the vehicle comfortably.
Locate the front jack spot, which on the 1997 Grand Prix is located just behind the front wheels. There will be a small indention on the underside of the carriage where the jack should be placed. Jack the Grand Prix up enough for you to be able to work underneath. Once the car is positioned, insert jack stands underneath the vehicle. Lower the car until it rests on the jack stands. Place a brick or block of wood behind the rear wheels of the Grand Prix to keep it in place.
Take the drain pan and move underneath the vehicle. Locate the power steering pump, which is located on the driver's side of the engine compartment, near the wheel shock strut. The power steering pump is contained in a small box, about 4 inches on a side. There will be a pulley connecting the pump to the engine.
Loosen the clamp on the power steering hose that you wish to change. Depending on the clamp, this can be done with the screwdriver or pliers. Gently pull the hose off the pump nipple. If this doesn't work, use the utility knife to slice the end of the hose off. Quickly aim the hose for the drain pan and allow the power steering fluid inside to drain out.
Unscrew the other end of the hose clamp from the other end of the power steering hose. Remove the hose, cutting if off, if needed.
Cut a new length of power steering hose, using the old hose as a guide. Apply a few drops of dish soap to the inside of both ends of the hose. Slip the hose over the power steering pump and system nipples. Secure the hoses with hose clamps.
Lower the car off the jack stands. Refill the power steering reservoir. Start the 1997 Grand Prix. Turn the steering wheel from side to side. Top off the steering fluid reservoir.
