How do I replace my 2008 Ford F150’s power steering fluid? 

Surprisingly,
servicing the power steering fluid
in your F150 is pretty straightforward. Here’s all you need to do: 
  • Find the power steering reservoir. You’ll find the reservoir marked with a steering wheel under the hood on the driver’s side of the engine. 
  • Remove the cap and insert a pump into the reservoir. You can use several options for a make-shift pump; for example, a turkey baster will do the job just fine.
  • Pump the old power steering fluid out of the reservoir. Use a container, like a coffee can, to catch the liquid you’re removing. 
  • Refill the reservoir with new fluid and replace the cap
You're good to go once you’ve replaced the power steering fluid in your F150. And with that, you’ve successfully changed your power steering fluid—easy peasy! If you’ve got the mechanical skills to go the extra mile, here are some additional steps for a complete replacement: 
  • Disconnect the fluid line. 
  • Drain the system. You may need an extra set of hands to help you start the engine and turn the steering wheel while the fluid drains into your drip pan. Repeat this process until fresh fluid is running into your pan.
  • Top off the reservoir and replace the cap. Make sure the fluid level is between the Min and Max fill lines. 
What if you’re not into DIY car maintenance? No problem! Take your F150 to your favorite mechanic. Let’s look at some pros and cons. 

Should I change it myself or take it to a mechanic?

At the end of the day, if you want to be confident that your replacement was done correctly, you can’t go wrong by having a professional do the work. A repair shop should be able to flush the steering fluid in an hour at most, and you’ll be looking to pay about $120
If you’re confident in your skills and have the tools, you can save money by completing this service yourself! You will still have to pay between $10 to $25 for the fluid, but you won’t have to pay labor fees.

When do I need to replace my 2008 Ford F150’s power steering fluid? 

Generally, you’ll want to replace your F150’s power steering fluid every two years or 75,000 miles, whichever comes first. This will keep your steering system in tip-top shape and help you steer easily. 
There are some instances where you’ll need to replace fluid before the scheduled time. If you notice any of these symptoms, it’s time to swap fluids: 
  • Strange noises when you turn the wheel (squealing, squeaking, etc.)
  • Difficulty steering
  • Bubbles in your power steering fluid
  • Fluid leakage
  • Color change from clear to yellow
Remember that sufficient power steering fluid doesn’t just help control your car—it extends its lifespan! Be sure to follow a
basic car maintenance schedule
to keep your F150 on the road for years.
