Why You Can't Directly Measure:
* Closed System: Unlike some older cars, the power steering system in a 1999 Explorer is a closed system with no dipstick.
* Reservoir Design: The reservoir is designed to have a specific amount of fluid, and overfilling can cause problems.
How to Check Power Steering Fluid Level:
1. Park on Level Ground: Make sure your Explorer is parked on a level surface.
2. Engine Off: Turn off the engine and let it cool down.
3. Locate Reservoir: The power steering fluid reservoir is usually located near the front of the engine compartment, often on the driver's side. It's a small, cylindrical container with a cap.
4. Check Fluid Level: The reservoir has a "MAX" and "MIN" mark on the side. With the engine off, the fluid level should be somewhere between these markings.
5. Look for Signs of Trouble:
* Low Fluid Level: If the fluid level is below the "MIN" mark, it needs to be topped off.
* Fluid Color and Condition: The fluid should be a reddish-brown color and clear. If it's dark or murky, it might need to be changed.
Important Notes:
* Proper Fluid: Use the correct type of power steering fluid as specified in your owner's manual or by a Ford dealership.
* Don't Overfill: Overfilling the reservoir can cause problems.
* Leak Check: If you notice a consistent low fluid level, check for leaks in the power steering system.
* Professional Help: If you're unsure or uncomfortable working on your vehicle, consult a qualified mechanic.
Remember, properly maintained power steering fluid ensures smooth steering and helps extend the life of your system.
