4. Setup and Installation
Proper installation is crucial for the longevity and performance of your power steering system. Follow these steps carefully:
4.1 Pre-Installation Checks
- Verify Compatibility: Confirm that the Edelmann 81236 is the correct return line hose assembly for your vehicle's make and model.
- Inspect Components: Before installation, visually inspect the new hose assembly for any signs of damage during shipping. Ensure all fittings are clean and free of debris.
- Gather Tools: Have all necessary tools ready, including wrenches, a drain pan, and new power steering fluid.
4.2 Installation Procedure
- Drain Fluid: Place a drain pan under the power steering system. Carefully disconnect the old return line hose and allow the power steering fluid to drain.
- Remove Old Hose: Disconnect the old hose assembly from all connection points. Note its routing to ensure the new hose is installed correctly.
- Install New Hose: Carefully route the new Edelmann 81236 Power Steering Return Line Hose Assembly into position, matching the original hose's path.
- Connect Fittings: Securely attach the 16MM Swivel O-Ring fitting and the 3/8 inch I.D. hose connections. Ensure all connections are tight to prevent leaks. The metal tubing is coated with a Zinc-Aluminum Alloy and an Aluminum-Rich Epoxy topcoat, and the couplings and fittings are zinc-plated for rust and corrosion protection.
- Secure Hose: Use the provided installation components (e.g., clamps) to secure the hose assembly, preventing contact with moving parts or hot engine components.
- Refill Fluid: Refill the power steering reservoir with the manufacturer-recommended power steering fluid to the appropriate level.
- Bleed System: Start the engine and slowly turn the steering wheel from lock to lock several times to bleed air from the system. Check the fluid level and top off as needed.
- Check for Leaks: With the engine running, carefully inspect all connections for any signs of leaks.

5. Operating and Post-Installation Checks
After installation, perform the following checks to ensure proper operation:
- Initial Drive: Drive the vehicle for a short period, paying attention to steering feel and any unusual noises.
- Re-check Fluid Level: After the system has circulated and cooled, re-check the power steering fluid level and top off if necessary.
- Leak Inspection: Conduct a thorough visual inspection for any leaks after the initial drive.
6. Maintenance
Regular maintenance helps extend the life of your power steering system and the Edelmann 81236 hose assembly.
- Periodic Inspection: Regularly inspect the power steering return line hose for signs of wear, cracks, bulges, or leaks. The hose construction is designed to withstand internal oil temperatures of up to 300 degrees Fahrenheit and is highly resistant to oil, heat, and ozone.
- Fluid Level Check: Check the power steering fluid level at recommended service intervals and top off with the correct fluid type as needed.
- Fluid Replacement: Follow your vehicle manufacturer's recommendations for power steering fluid replacement intervals.
