In a 2010 Lincoln MKZ, the power steering fluid is poured into the power steering reservoir located in the engine bay. The reservoir is typically on the driver’s side near the firewall and is clearly labeled “Power Steering Fluid.” Fill through the cap until the level reaches the full line with the engine off, then turn the steering wheel to bleed air from the system.
Locating the reservoir in the engine bay
To add or check fluid, locate the power steering reservoir first. It is a small translucent plastic bottle with a cap marked “Power Steering Fluid.” In the MKZ, this reservoir is usually positioned on the driver’s side of the engine bay near the firewall and adjacent to the power steering pump driven by the serpentine belt.
Before proceeding with any steps, refer to the vehicle’s manual for exact placement and markings, as minor variations can occur by production date.
Use these steps to locate and fill the reservoir correctly and safely:
- Open the hood and secure it safely.
- Find the power steering reservoir: translucent bottle with a cap labeled “Power Steering Fluid,” typically on the driver’s side near the firewall.
- Check the fluid level against the markings (MIN/MAX) if the reservoir is marked, or use the dipstick if present.
- With the engine off, remove the cap and slowly add the appropriate power steering fluid until the level reaches the full line.
- Replace the cap securely, start the engine, and gently turn the steering wheel from lock to lock to bleed air from the system.
- Turn off the engine and recheck the level once it has cooled; top up if necessary.
After completing these steps, monitor for any leaks and ensure the fluid level remains steady during normal driving. If you notice persistent low levels, there may be a leak in the power steering line, pump, or rack that should be inspected by a professional.
Fluid type and maintenance
Use the power steering fluid recommended by Ford for your MKZ. Many Ford-era vehicles accept Dexron- or Mercon-compatible fluids, and some newer formulations are synthetic blends. Check your owner’s manual or a Ford/Motorcraft product guide to confirm the exact specification. Avoid mixing fluids and keep the reservoir cap clean to prevent contamination.
Bleeding and troubleshooting
Bleeding the system is important after refilling to remove air pockets. Run the engine, turn the steering wheel fully left then fully right several times with the engine running, and recheck the fluid level. If the steering feels spongy or noisy, there may be air in the system or a leak that needs inspection.
What to do if you’re unsure
If you’re not comfortable performing these steps, or if the reservoir is difficult to locate, consult a qualified mechanic. Incorrect fluid type or improper filling can damage the power steering system over time.
Summary: The power steering fluid in a 2010 Lincoln MKZ goes into the power steering reservoir located in the engine bay on the driver’s side near the firewall. Fill with the recommended fluid until the full line is reached with the engine off, then bleed the system by turning the wheel from lock to lock. Always verify fluid type in the owner's manual and check for leaks after maintenance.
What is the power steering problem on a 2010 Lincoln MKZ?
The 2007 to 2008 and 2010 to 2012 models of the Lincoln MKZ may develop power steering fluid leaks somewhere in the power steering system. Most owners discover the issue when either they see a pool of power steering fluid under their vehicle or when they hear whining noises coming from their power steering pump.
Can you still drive if electric power steering goes out?
Technically, you can still drive with lost power steering, but it's not recommended. Without assistance, steering becomes much harder, especially at low speeds or during tight turns. Drivers who've lost power steering while driving often report sore arms and reduced vehicle control.
Where to put power steering fluid in Lincoln?
With the engine idling, turn the steering wheel all the way to full lock, and then turn it the other way to opposite lock. Do this several times. Locate the power steering reservoir. It is usually on or near the engine, and can have a white or yellow reservoir and a black cap.
Does Lincoln MKZ have electric power steering?
To move fluidly around every bend in the road, the Lincoln MKZ is armed with an electric power-assisted steering system.
