Installation (Setup)
The Gates 351300 Power Steering Repair Kit is designed for the repair of specific power steering components. Due to the complexity and critical nature of power steering systems, professional installation is strongly recommended.
General Installation Steps (Consult Vehicle Service Manual for Details):
- Preparation: Park the vehicle on a level surface, engage the parking brake, and allow the engine to cool.
- Access: Safely lift and support the vehicle. Access the power steering pump, rack and pinion, or control valve assembly as required for the specific seal replacement.
- Fluid Drainage: Drain the power steering fluid into a suitable container.
- Component Removal: Carefully remove the affected power steering component (e.g., pump, rack, control valve) from the vehicle.
- Disassembly: Disassemble the component to access the seals and bushings that need replacement. Note the orientation and position of all parts.
- Seal Replacement: Remove old seals and clean all mating surfaces thoroughly. Install new seals and bushings from the Gates kit, ensuring they are properly seated and lubricated with clean power steering fluid.
- Reassembly: Reassemble the power steering component, ensuring all fasteners are tightened to the manufacturer's specified torque.
- Reinstallation: Reinstall the repaired component back into the vehicle.
- Fluid Refill: Refill the power steering reservoir with the correct type of power steering fluid specified by your vehicle manufacturer.
- Bleeding the System: Follow the vehicle manufacturer's procedure for bleeding air from the power steering system. This typically involves turning the steering wheel lock-to-lock several times with the engine running.
- Leak Check: Inspect all connections for leaks after bleeding the system.
Always refer to your vehicle's specific service manual for detailed, model-specific instructions and torque specifications.
Operating Considerations (Post-Installation)
After installing the Gates Power Steering Repair Kit and refilling the system, observe the following:
- Fluid Level Check: Regularly check the power steering fluid level in the reservoir, especially during the first few days after installation. Top up as necessary.
- Steering Feel: The steering should feel smooth and consistent. Any unusual noises, stiffness, or looseness may indicate an issue.
- Leak Monitoring: Periodically inspect the repaired area for any signs of fluid leaks.
Maintenance
Proper maintenance of your power steering system can extend its lifespan and prevent future issues:
- Fluid Quality: Use only the type of power steering fluid recommended by your vehicle manufacturer.
- Fluid Changes: Consider periodic power steering fluid flushes or changes as recommended by your vehicle's service schedule. Contaminated or old fluid can degrade seals and components.
- Hose Inspection: Regularly inspect power steering hoses for cracks, leaks, or signs of wear.
- Belt Condition: Ensure the power steering pump belt is in good condition and properly tensioned.
Troubleshooting
If you experience issues after installing the repair kit, consider the following common problems and potential solutions:
| Symptom | Possible Cause | Action |
|---|---|---|
| Fluid Leak | Improperly seated seal, damaged component during installation, loose connection, or incorrect fluid. | Re-inspect all seals and connections. Ensure proper torque. Verify correct fluid type. If leak persists, professional diagnosis is required. |
| Noisy Power Steering (Whining/Groaning) | Low fluid level, air in the system, worn pump, or incorrect fluid. | Check fluid level and top up. Re-bleed the system. Inspect pump for wear. Ensure correct fluid is used. |
| Stiff Steering | Low fluid level, air in the system, worn pump, restricted line, or incorrect installation of components. | Check fluid level. Bleed the system. Inspect hoses for kinks or blockages. Verify all components were installed correctly. |
| Steering Wheel Vibration | Air in the system, worn pump, or issues with other steering/suspension components. | Bleed the system thoroughly. If vibration persists, consult a professional to diagnose the power steering pump or other related systems. |
If troubleshooting steps do not resolve the issue, it is advisable to seek assistance from a certified automotive technician.
