1. Compatibility Check:
- Before starting, make sure the existing steering column, steering rack, and suspension of your Mini Cooper can support power steering. Some models might require more significant modifications than others.
2. Gather Parts:
- Power steering rack (either new or used) designed or adapted for Mini Cooper. Consider the dimensions, mounting points, and compatibility with your vehicle's year and model.
- Power steering pump with reservoir.
- High-pressure and return power steering hoses.
- Power steering fluid.
- Steering column modifications might be necessary, depending on the power steering rack you select.
3. Steering Rack Installation:
- Remove the existing steering rack and modify the mounting points as required for the new power steering rack.
- Install the new power steering rack, making sure it's securely mounted.
4. Power Steering Pump and Reservoir Installation:
- Mount the power steering pump in a suitable location with consideration for belt alignment.
- Connect the high-pressure and return power steering hoses to the pump and the steering rack.
- Fill the reservoir with power steering fluid according to the vehicle's specifications.
5. Drive Belt Installation:
- Install a drive belt connecting the power steering pump to the engine's crankshaft or camshaft. Ensure proper tension and alignment of the belt.
6. Fluid Circuit Connections:
- Connect the fluid return line from the steering rack to the power steering pump reservoir.
7. Steering Column Modification:
- Depending on the power steering rack you selected, you might need to modify the steering column to accommodate the new rack's movements. This may involve replacing or adjusting the steering column universal joint.
8. Electrical Wiring:
- Some power steering racks may require electrical wiring for sensors or other components. Ensure proper wiring and connection to the vehicle's electrical system.
9. Fluid Leakage Check:
- Thoroughly inspect all fluid connections and hoses to ensure there are no leaks in the power steering system.
10. Alignment and Adjustment:
- Perform steering alignment and adjustment to ensure proper handling and steering response. It's recommended to have this done by a professional.
11. Test Drive and Adjustments:
- Take the Mini Cooper for a test drive to check the power steering functionality, steering weight, and any unusual behavior. Make any necessary adjustments.
12. Maintenance:
- Regularly check and maintain the power steering fluid level, inspect hoses for signs of wear or damage, and ensure the system remains free of leaks.
Remember, installing power steering in an old Mini Cooper is a complex task that requires careful planning and expertise.
