Disclaimer: Working on your vehicle carries inherent risks. If you're uncomfortable with any of these steps, take your Ranger to a qualified mechanic.
Tools and Materials You'll Need:
* New power steering fluid: Use the type specified in your owner's manual (usually ATF – Automatic Transmission Fluid). Get enough to completely flush the system.
* Large drain pan: To catch the old fluid.
* Wrench(es): Appropriate size for your power steering pump's return line fitting (often a 5/16" or 3/8" line). You may also need a wrench for the reservoir cap.
* New return line hose (optional but recommended): Power steering lines can deteriorate internally, so replacing the return line is a good idea during a flush.
* Funnel: To add new fluid to the reservoir.
* Jack and jack stands (highly recommended): For safer access to the return line.
* Gloves: To protect your hands from the old fluid.
* Clean rags or shop towels: For cleanup.
* Pressure washer (optional, but makes the process much cleaner): To flush debris from the system after draining.
Procedure:
1. Safety First: Always engage the parking brake and chock the wheels before working under your vehicle.
2. Locate the Power Steering Fluid Reservoir: This is usually a clear or translucent reservoir near the engine. Check your owner's manual for the exact location.
3. Locate the Power Steering Pump Return Line: This is the line that returns fluid *from* the steering gear *to* the reservoir. It's usually a smaller diameter line. Consult your repair manual or a diagram for the precise location; it's typically near the pump itself.
4. Prepare for Draining: Place the drain pan under the return line.
5. Disconnect the Return Line: Carefully loosen and remove the return line from the reservoir. Be prepared for some fluid to spill. *This is the crucial step to thoroughly flush the system*.
6. Start the Engine (with caution): Start the engine and immediately let it run for only about 15-20 seconds. The pump will circulate the old fluid out of the return line, and into your drain pan. Turn the steering wheel back and forth slowly while the engine runs to encourage fluid flow.
7. Check Fluid Level: Turn off the engine and check the fluid level in the reservoir.
8. Repeat: Reconnect the return line, refill the reservoir with fresh fluid (to the appropriate level), and repeat steps 5 and 6 several times until the exiting fluid appears clean. You may have to add more new fluid as you drain the old fluid. If you are using a pressure washer, you can use it at this step to further clean the system.
9. (Optional) Replace the Return Line: If the return line appears deteriorated, replace it now.
10. Reconnect the Return Line: Securely reconnect the return line.
11. Fill the Reservoir: Add fresh power steering fluid to the reservoir, checking the level frequently. Follow your owner's manual for the correct fluid level.
12. Top Off and Test: Start the engine and turn the steering wheel back and forth fully to circulate the new fluid. Turn off the engine, and top off the fluid level as needed.
Important Considerations:
* Repair Manual: Using a repair manual specific to your 2000 Ford Ranger is highly recommended. It will provide diagrams and detailed instructions.
* Fluid Type: Use the correct type of power steering fluid. Using the wrong fluid can damage your power steering system.
* Air Bubbles: Air bubbles in the system can cause problems. Make sure the reservoir is full, and consider gently tapping on the lines to help dislodge any trapped air. There is usually a small bleed valve to release air, as well, but this is not always present.
* Professional Help: If you're not comfortable performing this procedure yourself, take your Ranger to a qualified mechanic.
This detailed procedure should help you flush your power steering fluid. Remember to prioritize safety and consult your vehicle's owner's manual for specific recommendations.
