Here's a general outline. Consult a repair manual specific to your 1993 Ford Taurus for detailed instructions, diagrams, torque specifications, and component locations. The model year and trim level can influence the specifics.
1. Preparation:
* Safety First: Disconnect the negative battery terminal.
* Gather Supplies: You'll need new power steering lines (get the correct ones from a parts store – providing your VIN is helpful), wrenches (metric), socket set, open-end wrenches, pliers, a drain pan, shop rags, power steering fluid (the correct type for your car), a funnel, and possibly a tubing bender (depending on line routing). A pressure bleeder may also make the process easier.
* Vehicle Preparation: Raise the vehicle securely on jack stands. Never work under a vehicle supported only by a jack.
2. Locating and Removing the Old Lines:
* Identify Lines: Carefully trace the power steering lines from the pump to the steering gear. There might be multiple lines (high-pressure and return).
* Disconnect Lines: Use the appropriate wrenches to disconnect the lines at both ends (pump and steering gear). Be prepared for fluid spillage – that's why you have the drain pan.
* Note Routing: Pay close attention to how the lines are routed. Take pictures or make detailed notes. This is crucial for reinstallation.
* Remove Lines: Carefully remove the old lines. They might be clamped or secured in various places.
3. Installing the New Lines:
* Prepare New Lines: If necessary, flare the ends of the new lines according to the specifications in your repair manual. This requires special flaring tools.
* Route New Lines: Carefully route the new lines, following the path of the old lines. Use clamps and brackets as needed.
* Connect Lines: Connect the new lines to the pump and steering gear. Tighten fittings to the manufacturer's specifications (your repair manual is essential here).
* Check for Leaks: Visually inspect all connections for leaks.
4. Filling and Bleeding the System:
* Fill Reservoir: Add power steering fluid to the reservoir, checking the level frequently. Use the correct type of fluid as specified in your owner's manual.
* Bleeding the System: This is essential to remove air from the system. There are different methods; consult your repair manual. One common method involves turning the steering wheel lock-to-lock while the engine is running, repeatedly checking and topping off the fluid level. A pressure bleeder significantly simplifies this process.
* Check Fluid Level: Once air is removed and the system is full, check for leaks again.
5. Lower the Vehicle and Test:
* Lower the Vehicle: Carefully lower the vehicle from the jack stands.
* Test Drive: Test drive the vehicle and check for leaks or unusual noises. The power steering should work smoothly.
Important Considerations:
* Repair Manual: A factory service manual is highly recommended. It will provide detailed diagrams, torque specifications, and specific instructions for your vehicle.
* Professional Help: If you're not comfortable working on your vehicle, consider taking it to a qualified mechanic. Power steering repair can be tricky, and mistakes can lead to further damage or injury.
* Fluid Type: Use the correct type and amount of power steering fluid. Using the wrong fluid can damage the system.
* Line Bending: If you need to bend the lines, use a tubing bender to avoid kinking and restricting fluid flow.
This is a general guide. Consult a repair manual specific to your vehicle for detailed instructions and safety precautions. Always prioritize safety when working on your vehicle.
