This procedure removes and replaces the power steering pump on 2016-2024 Hyundai Tucson models equipped with the 2.5L I4 engine and AWD. Note that these models use electric power steering and do not have a traditional hydraulic pump.

Warnings

Tools required

Parts

• Electric power steering motor/pump assembly × 1 — Use OEM specification
• Power steering pump mounting bolts × 2 — Reuse if threads are good

Preparation

1. Park vehicle on level ground and engage parking brake
2. Disconnect battery negative terminal and wait 3 minutes minimum
3. Allow engine to cool completely (minimum 2 hours after operation)
4. Raise front of vehicle and secure on jack stands at manufacturer lift points
5. Remove front passenger-side wheel for access to EPS unit
6. Remove plastic engine undershield if equipped (multiple 10mm bolts and push clips)

Procedure

1. 1

   Remove serpentine belt
   Locate the serpentine belt tensioner on the front of the engine. Using a 3/8" breaker bar or belt tool, rotate the tensioner clockwise to release tension. Slide the belt off the pulleys and slowly release tensioner. Remove belt from engine bay. Take a photo or diagram of belt routing before removal for reinstallation reference.
2. 2

   Disconnect EPS electrical connector
   Locate the electric power steering motor assembly on the lower passenger side of the engine bay, near the steering rack. Press the release tab on the main EPS electrical connector and pull connector straight off. Do not pull on wires. If connector is corroded, use electrical contact cleaner before disconnecting.
3. 3

   Remove air intake components for access
   Loosen the clamp on the air intake tube where it connects to the throttle body. Disconnect any air temperature sensors or breather hoses. Remove the air intake tube and air filter housing assembly to provide clear access to the EPS motor. Set components aside in clean area.
4. 4

   Disconnect EPS wiring harness brackets
   The EPS motor wiring harness is secured by several plastic clips and possibly a metal bracket to the subframe. Carefully release all clips and remove any 10mm bolts securing wiring brackets. Leave enough slack to allow the harness to move with the motor during removal.
5. 5

   Remove EPS motor mounting bolts
   Locate the two or three mounting bolts securing the EPS motor to the steering rack assembly. These are typically 12mm or 14mm head bolts. Support the motor with one hand while removing the final bolt. Remove all mounting bolts and carefully note their positions as they may be different lengths.

6. 6

   Remove EPS motor assembly
   With all bolts removed, carefully pull the EPS motor straight out from the steering rack. The motor shaft engages with the rack pinion, so pull firmly but steadily. Wiggle slightly if needed but do not pry against steering rack housing. Once shaft is clear, remove motor from engine bay.
   ⚠Do not allow the motor shaft to strike the steering rack housing during removal as this can damage the precision pinion gears.
7. 7

   Clean mounting surface and inspect
   With the old EPS motor removed, use a wire brush to clean the mounting surface on the steering rack. Inspect the rack housing for any cracks or damage. Check the pinion shaft opening for debris or metal shavings which could indicate internal rack damage. Clean any dirt or oil from mounting bolt holes.
8. 8

   Install new EPS motor assembly
   Align the new EPS motor shaft with the pinion opening on the steering rack. The shaft has a splined connection that must align properly. Rotate the motor shaft slightly while pushing in until it engages fully. Push motor flush against mounting surface ensuring proper seating before installing bolts.
9. 9

   Install and torque mounting bolts
   Install all EPS motor mounting bolts hand-tight first to ensure proper alignment. Once all bolts are started, torque them in a cross pattern to specification. Verify motor is seated flush against rack housing with no gaps.
   ⚠Over-torquing mounting bolts can crack the EPS motor housing or distort the rack assembly. Use calibrated torque wrench.

10. 10

    Reconnect electrical connector and harness
    Plug the main EPS electrical connector back onto the motor until it clicks securely. Tug gently to verify connection. Reinstall all wiring harness brackets and clips to secure harness properly. Ensure wiring is routed away from heat sources and moving components.
11. 11

    Reinstall air intake components
    Reinstall the air filter housing and intake tube in reverse order of removal. Reconnect all sensors and breather hoses. Tighten intake tube clamp at throttle body securely but do not over-tighten plastic components.
12. 12

    Reinstall serpentine belt
    Route serpentine belt around all pulleys according to the diagram (should be on radiator shroud or reference your photo). Rotate tensioner clockwise and slip belt onto final pulley. Slowly release tensioner to apply proper belt tension. Verify belt is centered on all pulleys.
13. 13

    Reinstall wheel and undershield
    Reinstall plastic engine undershield using all original fasteners and clips. Install front passenger wheel and hand-tighten lug nuts in star pattern. Lower vehicle to ground and torque lug nuts to specification in star pattern.
14. 14

    Reconnect battery and perform steering initialization
    Reconnect battery negative terminal. Turn ignition to ON position (engine off) and turn steering wheel fully left and right several times to allow the EPS system to initialize and calibrate. Start engine and verify no warning lights remain illuminated on dash.

Reassembly

1. All components should be reinstalled in reverse order of removal
2. Ensure all electrical connectors are fully seated and locked
3. Verify serpentine belt is properly routed and tensioned
4. Double-check that all wiring harnesses are secured away from moving parts

Verification

• Start engine and verify no EPS warning light on instrument cluster
• Turn steering wheel lock-to-lock while stationary - should feel smooth with no binding or unusual noises
• Test drive vehicle at low speed in parking lot - steering assist should function normally with light effort
• Verify no clicking, grinding, or whining noises from steering system during operation
• Check for any diagnostic trouble codes using OBD-II scanner - clear any learned codes from old motor if present
• Verify all warning lights are off after test drive and system initialization is complete
