Power Steering Hose - High Pressure

This procedure replaces the high-pressure power steering hose on 2018-2024 Toyota Camry 2.5L I4 models equipped with hydraulic power steering systems.

Warnings

Tools required

Parts

• High pressure power steering hose × 1 — Use OEM specification
• Power steering fluid O-rings × 2 — Included with hose or order separately
• Power steering fluid × 1 — Toyota Genuine ATF WS or equivalent

Fluids

• Toyota WS ATF (for power steering) — 1 qt

Preparation

1. Verify your vehicle has hydraulic power steering by checking for a power steering fluid reservoir near the engine bay
2. Park vehicle on level ground and engage parking brake
3. Raise front of vehicle and support securely on jack stands
4. Remove front splash shield or undertray if necessary for access
5. Place drain pan under power steering pump and rack area
6. Use turkey baster to remove as much fluid as possible from power steering reservoir

Procedure

1. 1

   Access the high pressure hose at pump
   Locate the high pressure power steering hose connection at the power steering pump on the front of the engine. Clean the area around the fitting to prevent contamination. The pump is typically mounted to the front lower portion of the engine block.
2. 2

   Disconnect hose from power steering pump
   Using a 19mm flare nut wrench, carefully loosen the high pressure hose fitting at the power steering pump. Have a drain pan ready as fluid will drain from both the hose and pump. Remove the banjo bolt or threaded fitting completely and allow fluid to drain. Cap or plug the pump outlet to prevent contamination.
   ⚠Use a flare nut wrench to prevent rounding off the soft aluminum fittings. Do not use standard open-end wrenches.
3. 3

   Trace hose routing
   Follow the high pressure hose from the pump to the steering rack. Note any clips, brackets, or routing guides that secure the hose. Take a photo for reference during installation. Remove any retaining clips securing the hose to the vehicle body or engine compartment.
4. 4

   Access steering rack connection
   From underneath the vehicle, locate where the high pressure hose connects to the steering rack on the driver side. Clean the area around the fitting thoroughly. The connection point is typically on the side of the rack housing near the inner tie rod.
5. 5

   Disconnect hose from steering rack
   Using a 17mm flare nut wrench, loosen the high pressure hose fitting at the steering rack. Allow remaining fluid to drain into the drain pan. Once loose, unthread the fitting by hand and remove the hose. Note the position of any washers or seals.
6. 6

   Remove old hose from vehicle
   Carefully extract the high pressure hose from the engine bay, noting its routing path. Remove it from any remaining clips or guides. Inspect the old hose for signs of wear, cracking, or failure points.
7. 7

   Prepare new hose
   Compare the new high pressure hose to the old one to verify correct length and end fittings. Install new O-rings on both ends of the new hose if they are not pre-installed. Lightly lubricate the O-rings with clean power steering fluid to ease installation and prevent tearing.
   ⚠Always use new O-rings. Reusing old O-rings will cause leaks.
8. 8

   Route new hose
   Route the new high pressure hose along the same path as the old hose, ensuring it does not contact any sharp edges, hot exhaust components, or moving parts. Install the hose into any routing clips or guides, leaving the fittings loose for now.
9. 9

   Connect hose to steering rack
   Thread the fitting at the steering rack end by hand to ensure proper alignment and prevent cross-threading. Once hand-tight, use the 17mm flare nut wrench to tighten the fitting to the specified torque of 30 Nm (22 lb-ft). Ensure the O-ring is properly seated.
   ⚠Do not over-tighten. Excessive torque can damage the aluminum threads in the rack housing.

10. 10

    Connect hose to power steering pump
    Thread the fitting at the pump end by hand first to ensure proper thread engagement. Once hand-tight, use the 19mm flare nut wrench to tighten the fitting to the specified torque of 30 Nm (22 lb-ft). Verify the O-ring is properly seated and the connection is secure.

11. 11

    Secure hose routing
    Verify the hose is properly seated in all routing clips and brackets. Ensure there is adequate clearance from the exhaust manifold, engine mount, and any moving components. The hose should not be twisted or kinked.
12. 12

    Fill power steering system
    Fill the power steering reservoir with fresh Toyota WS ATF to the cold fill line. Turn the steering wheel lock-to-lock several times without starting the engine to distribute fluid through the system. Check reservoir level and add fluid as needed.
13. 13

    Bleed air from system
    Start the engine and allow it to idle. Turn the steering wheel slowly from lock to lock 3-5 times. Check for leaks at both connections. Stop the engine and check the fluid level, adding fluid to bring it to the proper level. Repeat this process until no air bubbles appear in the reservoir and the fluid level stabilizes.
    ⚠Do not hold the steering wheel at full lock for more than 5 seconds to avoid pump damage.

Reassembly

1. Reinstall any splash shields or undertray panels removed for access
2. Lower vehicle from jack stands
3. Top off power steering fluid to the proper cold level
4. Wipe down all connections and surrounding areas to identify any fresh leaks

Verification

• Start the engine and verify no leaks at either connection point
• Turn the steering wheel lock-to-lock while someone observes the connections for leaks
• Check power steering fluid level and verify it is at the proper mark
• Test drive the vehicle and verify normal power steering operation with no noise or binding
• Recheck all connections and fluid level after test drive
• Monitor the area under the vehicle for 24 hours for any delayed fluid leaks
