Learn how to check and top up the power steering fluid on your 1968 Ford Mustang GT Fastback (Bullitt) with our simple step-by-step guide. Ensure your classic car runs effortlessly!

Experiencing difficulty with your power steering can significantly impact your driving experience, and ensuring your power steering fluid is at the correct level is crucial for maintaining smooth and responsive steering. If you notice difficulty in steering your 1968 Ford Mustang GT Fastback, commonly known as Bullitt, or hear whining noise when you turn the wheel, it may indicate that your power steering fluid is low. Here is how to solve this issue:

Step 1: Gather Materials

  • Power steering fluid suitable for a 1968 Ford Mustang GT Fastback
  • Clean rag
  • Funnel

Step 2: Locate the Power Steering Fluid Reservoir
Open the hood of your Mustang and locate the power steering fluid reservoir. The reservoir is usually found towards the front of the engine bay on the driver’s side. It has a metal cap marked "Power Steering."

Step 3: Check the Fluid Level
To check the fluid level, first, ensure the engine is turned off and has cooled down. Carefully unscrew the cap of the reservoir. Using the dipstick attached to the underside of the cap, check the fluid level. Wipe the dipstick with a clean rag and reinsert it to get an accurate reading. Make sure the fluid level is within the "Full" mark on the dipstick.

Step 4: Refill the Power Steering Fluid
If the fluid level is low, place a funnel into the reservoir opening. Pour the power steering fluid slowly into the reservoir, checking frequently to avoid overfilling. Fill until the fluid reaches the "Full" mark on the dipstick. Be careful not to spill any fluid on the engine components, as it can cause damage or create a mess.

Step 5: Replace the Cap and Clean Up
Once the fluid is at the proper level, remove the funnel and screw the cap back onto the reservoir securely. Wipe any spilled fluid from around the reservoir and engine bay using the clean rag to ensure cleanliness and avoid any potential hazards.

Step 6: Test the Steering
Start your Mustang and let it idle for a few minutes. Turn the steering wheel from lock to lock a few times to circulate the fluid through the system. If the steering feels smooth and responsive, and no whining noises are heard, the fluid level should now be adequate.

By following these steps, you’ve ensured that your Mustang's power steering system is properly maintained, which in turn should lead to a smoother, safer driving experience.
