Safety First:
* Wear safety glasses: Power steering fluid can splash.
* Work in a well-ventilated area: Power steering fluid has a strong odor.
* Dispose of used fluid properly: Power steering fluid is hazardous waste; check with your local authorities for proper disposal methods.
* Have the correct type of fluid: Use only the fluid specified for your Corvette's power steering system. This is usually Dexron type ATF (Automatic Transmission Fluid). Check your owner's manual to be absolutely certain.
Tools and Materials:
* New power steering fluid: The correct type and amount (check your owner's manual).
* Wrench to fit power steering pump pressure line fitting: This is usually a flare-nut wrench, and the size varies by year, so have a few sizes ready
* Wrench to fit power steering fluid return line fitting: May be the same size as the pressure line fitting or different.
* Drain pan: To catch the old fluid.
* Funnel: To add new fluid.
* Jack and jack stands: To safely lift the car. Never work under a car supported only by a jack.
* Gloves: To protect your hands.
* Rags or shop towels: For cleaning up spills.
* A helper: (optional, but helpful)
Procedure:
1. Prepare the car: Jack up the front of the car and securely support it on jack stands.
2. Locate the power steering fluid reservoir: This is usually a small reservoir near the power steering pump.
3. Check the fluid level: Note the current level before draining.
4. Drain the fluid: Locate the drain plug on the power steering gear or pump. If there is no drain plug, you will need to disconnect the return line to drain the system. Place your drain pan underneath and carefully loosen and remove the plug or line. Let the fluid drain completely.
5. Reconnect the drain line (if applicable): If you disconnected the return line, carefully reconnect it making sure the connection is tight and secure. Avoid over-tightening.
6. Fill the reservoir: Use a funnel to add the correct type of power steering fluid to the reservoir. Refer to your owner's manual for the correct fluid type and fill level.
7. Start the engine: With the engine running, turn the steering wheel slowly and fully lock-to-lock several times. This circulates the fluid and removes air bubbles.
8. Check the fluid level: Turn off the engine and check the fluid level in the reservoir. Add more fluid as needed to reach the proper level.
9. Check for leaks: Inspect the power steering system for any leaks.
10. Lower the car: Carefully lower the car from the jack stands.
Important Notes:
* Air Bubbles: Air in the power steering system can cause problems. It's crucial to turn the steering wheel fully lock-to-lock several times to bleed the air out of the system. If you still experience issues after this, you might have a more serious problem requiring professional attention.
* Fluid Type: Using the incorrect fluid can damage your power steering system. Always double-check your owner's manual.
* Difficulty: If you find the drain plug or return line difficult to access or remove, consider seeking professional help. Some components might be rusted or seized.
This process is a general guide. Refer to a Corvette-specific repair manual for detailed instructions and diagrams relevant to your specific model year. If you are not comfortable performing this task yourself, it's best to take your Corvette to a qualified mechanic.
