🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect power and open access

• Use a 10mm socket to disconnect the negative battery cable.
• Remove the engine cover if equipped.
• If needed, raise the front of the vehicle with a floor jack and support it with jack stands.

Step 2: Remove the drive belt

• Use a serpentine belt tool or long-handled breaker bar to relieve belt tension.
• Slip the belt off the power steering pump pulley.
• Remove the belt from the engine bay.
• Take a quick belt-routing photo first.

Step 3: Drain the power steering reservoir

• Use a drain pan under the vehicle.
• Remove fluid from the reservoir with a suction tool if available, or disconnect the return hose carefully.
• Catch and dispose of old fluid properly.

Step 4: Disconnect the hoses

• Use a line wrench set to loosen the pressure line fitting.
• Use pliers to release the return hose clamp.
• Cap or plug the openings to keep dirt out.
• Replace all sealing washers or O-rings with new ones.

Step 5: Remove the pump

• Use a 12mm socket and 14mm socket to remove the pump mounting bolts.
• Lift the pump out of the bracket.
• If the pulley must transfer to the new pump, use a pulley puller (specialty).

Step 6: Install the new pump

• Position the new pump in place.
• Install the mounting bolts by hand first with a 12mm socket or 14mm socket.
• Tighten the pump mounting bolts to factory specification.
• Reinstall the pulley if removed using the proper pulley installer tool.

Step 7: Reconnect hoses

• Install new sealing washers or O-rings on the pressure side.
• Use a line wrench set to tighten the pressure fitting.
• Reattach the return hose and clamp.
• Tighten all hose connections to factory specification.

Step 8: Reinstall the belt

• Route the belt correctly around all pulleys.
• Use the serpentine belt tool or long-handled breaker bar to release tension.
• Confirm the belt sits fully in each pulley groove.

Step 9: Refill 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 lock-to-lock several times.
• Top off the fluid as the level drops.
• Start the engine and repeat the slow steering cycles.
• Do not hold the wheel against the stop for more than a second.

Step 10: Check for leaks and finish

• Inspect the pump, hose fittings, and reservoir for leaks.
• Reinstall the engine cover.
• Reconnect the negative battery cable with a 10mm socket.
