Power Steering Fluid Type

The Pontiac Grand Prix requires GM Power Steering Fluid or an equivalent. The specific part numbers for GM Power Steering Fluid are:

  • GM Part No. U.S. 98021184
  • GM Part No. Canada 89021186

These part numbers have been superseded by part number 19329450. If you can't find the GM-specific fluid, a universal power steering fluid from a reputable brand like Lucas can be used as an alternative.

Locating the Reservoir

Finding the power steering fluid reservoir in a Pontiac Grand Prix can be challenging due to its unconventional placement. To locate it:

1. Look on the passenger side towards the back of the engine compartment

2. Find the coolant reservoir

3. Remove the two bolts holding the coolant reservoir in place

4. Look underneath and to the right

5. You should see the power steering reservoir cap with a steering wheel emblem

Fluid Change Procedure

Changing the power steering fluid in your Pontiac Grand Prix involves these steps:

1. Remove old fluid: Use a fluid extractor syringe to remove old fluid from the reservoir

2. Refill: Add new fluid to the correct level

3. Bleed the system: Start the engine and slowly turn the steering wheel from lock to lock a few times

4. Check level: Turn off the engine and recheck the fluid level

5. Repeat: Continue this process until the fluid appears clean

Important: Do not hold the steering wheel at full lock during this process.

Fluid Maintenance

Regular maintenance of your power steering fluid can prevent issues such as:

  • Whining or squealing noises when steering
  • Increased effort required to turn the wheel
  • Potential damage to the power steering pump or rack and pinion

It's recommended to check your power steering fluid level and condition regularly, similar to how you would maintain your transmission fluid.

Tips for Fluid Change

  • Use a long funnel (12-13 inches) to reach the reservoir easily
  • Consider using a vacuum pump for a more thorough fluid exchange
  • Be prepared for some spillage - place rags around the work area
  • The process may need to be repeated several times to fully flush the system

Remember, while changing the power steering fluid can often resolve steering issues, persistent problems may indicate other issues within the power steering system that require professional attention.
