Steps
Record belt routing and release tension
Note the belt path shown on the underhood diagram. Use the appropriate socket and breaker bar to rotate the tensioner, slip the belt off the pump pulley, and release the tensioner slowly.
Drain and disconnect the pump
Protect nearby components with absorbent material and drain the reservoir and pump into a pan. Move the low-pressure hose clamp, disconnect the return hose, and remove the high-pressure line fasteners.
Remove the pump
Lift the pressure line clear and remove the pump mounting bolts. Raise the pump out of the engine bay and capture any remaining fluid for proper disposal.
Transfer the pulley
Use a suitable pulley holding and removal tool to remove the pulley from the old pump without bending it. Install it on the replacement pump using the correct service procedure.
Install the replacement pump
Remove shipping plugs, position the pump, and tighten its mounts to the vehicle's specification. Prime the pump with the specified fluid, install a new line O-ring, and reconnect both hoses.
Reinstall the serpentine belt
Route the belt over each pulley according to the diagram. Rotate the tensioner, seat the belt fully on the pump pulley, then release the tensioner and verify alignment.
Fill and bleed the steering system
Fill the reservoir with the specified fluid. With the front wheels safely raised if required, turn the steering slowly side to side without holding at full lock; recheck the level and repeat until air is gone.
Check for leaks and operation
Start the engine and inspect the pump and hose connections for leaks or abnormal noise. Recheck fluid level after the system settles and confirm steering assist is smooth.
Check your vehicle’s repair manual for exact specifications and fit.
