🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover and gain access

• Remove the engine cover by hand if equipped.
• Use a 10mm socket to remove any intake ducting or brackets blocking access to the pump.

Step 2: Remove the serpentine belt

• Use a serpentine belt tool or long-handled breaker bar to rotate the belt tensioner.
• Slip the belt off the power steering pump pulley.
• Note the belt routing before removal. Take a quick photo first.

Step 3: Drain the power steering fluid

• Place a drain pan under the pump and hoses.
• Remove the reservoir cap.
• Use a line wrench if needed, then disconnect the return hose first and let the fluid drain.

Step 4: Disconnect the hoses

• Use a line wrench set to remove the high-pressure line fitting from the pump.
• Remove the return hose clamp and hose.
• Cap or cover open lines to keep dirt out.

Step 5: Remove the pump

• Use a 14mm socket and 12mm socket to remove the pump mounting bolts.
• Lift the pump out of the bracket carefully.
• If a bracket is attached, remove it only if needed for access.

Step 6: Transfer any brackets or pulley if needed

• If your replacement pump does not come with the pulley, transfer the pulley using the correct pulley installer/remover (specialty).
• Transfer any mounting brackets from the old pump to the new one.
• Do not hammer on the pulley.

Step 7: Install the new pump

• Set the new pump in place and start all bolts by hand.
• Use a 12mm socket and 14mm socket to tighten the mounting bolts.
• Torque to 39 Nm (29 ft-lbs) unless your replacement pump instructions specify otherwise.

Step 8: Reconnect the hoses

• Install new O-ring seals on the pressure line fitting if supplied.
• Use a line wrench set to reinstall the high-pressure line.
• Reconnect the return hose and clamp securely.
• Torque the pressure line fitting to 34 Nm (25 ft-lbs).

Step 9: Reinstall the serpentine belt

• Route the belt back over all pulleys using the correct factory path.
• Use the serpentine belt tool or long-handled breaker bar to release the tensioner and slip the belt onto the last pulley.
• Make sure the belt sits fully in every pulley groove.

Step 10: Fill and bleed the system

• Use a funnel to fill the reservoir with the correct power steering fluid.
• With the front wheels off the ground, turn the steering wheel slowly from lock to lock several times.
• Top off the fluid as the air works out.
• Do not hold the wheel against the stop for more than 2-3 seconds.

Step 11: Check for leaks and noise

• Start the engine and let it idle.
• Inspect the pump, hose fittings, and reservoir for leaks.
• Listen for whining. A little noise at first can be normal while air escapes.

✅ After Repair
