This procedure replaces the power steering return hose on 2016-2024 Hyundai Tucson models equipped with the 2.5L I4 engine and AWD. Note: These models use electric power steering and do not have traditional hydraulic power steering hoses.

Warnings

Tools required

Parts

• Power steering return hose (if equipped) × 1 — Use OEM specification
• Hose clamps × 2 — Use OEM specification

Preparation

1. Verify your vehicle actually has a hydraulic power steering system by checking for a power steering fluid reservoir in the engine bay. Most 2016-2024 Tucson models use electric power steering.
2. Park vehicle on level ground and engage parking brake
3. Place wheel chocks behind rear wheels
4. If hydraulic power steering is confirmed, locate and identify the return hose routing from the steering rack to the reservoir
5. Raise front of vehicle using floor jack and support securely on jack stands
6. Remove front driver side wheel to improve access if needed

Procedure

1. 1

   Access the power steering components
   Remove any necessary undertray panels or splash shields to access the steering rack area. Most access will be from underneath the vehicle. Use trim removal tools to avoid breaking clips.
2. 2

   Identify return hose routing
   Locate the power steering return hose. The return hose is the low-pressure line running from the steering rack back to the reservoir. It is typically smaller diameter than the pressure hose and uses spring clamps or worm-drive clamps rather than threaded fittings.
3. 3

   Drain remaining fluid
   Position drain pan beneath the hose connections. If accessible, remove the power steering reservoir cap to allow easier drainage. Use a fluid transfer pump to remove as much fluid as possible from the reservoir before disconnecting lines.
   ⚠Power steering fluid can be slippery. Clean up any spills immediately to prevent falls or contamination of other components.
4. 4

   Disconnect hose at reservoir
   Using pliers or a hose clamp tool, compress or loosen the clamp at the reservoir connection. Slide the clamp back along the hose. Gently twist and pull the hose off the reservoir nipple. Allow fluid to drain into the pan.
5. 5

   Disconnect hose at steering rack
   Locate the return hose connection at the steering rack. Release the clamp using pliers or appropriate tool, slide it back, and remove the hose from the rack fitting. Allow any remaining fluid to drain completely.
6. 6

   Remove return hose
   Trace the hose routing and release any clips or brackets securing the hose to the chassis or other components. Remove the old return hose from the vehicle. Note the exact routing for installation of the new hose.
7. 7

   Install new return hose
   Route the new return hose following the same path as the original. Ensure the hose does not contact any sharp edges, hot components, or moving parts. The hose should have no kinks or tight bends that could restrict flow.
8. 8

   Connect hose at steering rack
   Push the hose firmly onto the steering rack return fitting until it seats completely. Install a new hose clamp and position it approximately 10mm from the end of the hose. Tighten the clamp securely but avoid over-tightening which could damage the hose.
9. 9

   Connect hose at reservoir
   Push the hose firmly onto the reservoir return nipple until fully seated. Install a new clamp, position it properly, and tighten securely. Verify both connections are secure and hose is properly routed.
10. 10

    Secure hose routing
    Reinstall all routing clips and brackets to secure the hose in its proper position. Ensure adequate clearance from exhaust components, suspension parts, and the drive axle.
11. 11

    Reinstall underbody panels
    Reinstall any splash shields or undertray panels that were removed. Ensure all clips and fasteners are properly seated.
12. 12

    Reinstall wheel
    If the front wheel was removed, reinstall it and hand-tighten lug nuts in a star pattern. Lower the vehicle to the ground and torque lug nuts to specification in a star pattern.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. If hydraulic power steering is present, refill the reservoir with the appropriate power steering fluid to the MAX line
2. Start the engine and turn the steering wheel lock-to-lock several times to bleed air from the system
3. Check fluid level and top off as needed
4. Inspect all connections for leaks while engine is running and steering is being cycled
5. Road test the vehicle and verify normal power steering operation with no leaks

Verification

• Check for fluid leaks at both hose connections with engine running
• Verify power steering operates smoothly with no unusual noises
• Confirm fluid level is at the proper mark on the reservoir
• Inspect hose routing to ensure no contact with moving or hot components
• Re-check all connections after a short test drive
