🔧 Civic - Power Steering Pump Replacement

Your Civic’s power steering pump makes the hydraulic pressure that helps you turn the wheel easily. If the pump is leaking, whining, or losing assist, replacing it restores proper pressure and prevents fluid from damaging belts and other components.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; keep hands clear of belts and pulleys.
• ⚠️ Use jack stands if you raise the front; never rely on a floor jack alone.
• ⚠️ Power steering fluid is slippery and flammable—wipe spills immediately and keep away from hot exhaust.
• ⚠️ Avoid turning the wheel hard-stop to hard-stop for long; it can over-pressurize the system.
• ⚠️ Battery disconnect is recommended to prevent accidental shorts near the alternator.

📋 Before You Begin

• Park on level ground, put the transmission in 1st gear, and set the parking brake.
• Chock the rear wheels with wheel chocks.
• Open the hood and disconnect the negative battery cable using a 10mm wrench.
• Suck out as much fluid as possible from the reservoir using a turkey baster or fluid suction pump into a drain pan.
• If you want easier bleeding, raise the front and support it on jack stands (front tires off the ground).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the accessory drive belt

• Locate the belt tensioner/adjuster for the power steering belt path at the pump area.
• Use a 12mm socket and ratchet to loosen the pump lock/pivot bolts, then back off the adjuster bolt until the belt is loose.
• Slip the belt off the power steering pump pulley by hand.

Step 2: Disconnect the return hose (low-pressure)

• Place a drain pan under the pump.
• Use hose clamp pliers to slide the clamp back on the return hose.
• Twist the hose gently to break it free, then pull it off the pump nipple and let it drain.
• Tip: A small twist prevents tearing the hose.

Step 3: Disconnect the pressure line (high-pressure)

• Clean around the fitting with shop rags so dirt doesn’t enter the system.
• Use a line wrench (14mm or 17mm) to loosen the pressure fitting/banjo bolt (size varies by hose design).
• Remove the bolt/fitting and catch remaining fluid in the drain pan.
• Remove and discard the old pressure line sealing washers (there are typically two: one on each side of the fitting).

Step 4: Unbolt and remove the power steering pump

• Use a 12mm socket and ratchet to remove the pump mounting bolts.
• Lift the pump out of the engine bay.

Step 5: Transfer the pulley (only if your new pump does not include one)

• If your replacement pump comes with a pulley already installed, skip this step.
• Use a power steering pulley puller/installer (specialty) to pull the pulley off the old pump.
• Install the pulley onto the new pump using the same pulley puller/installer (specialty).
• Pulley must sit straight; don’t hammer it on.

Step 6: Install the new pump

• Position the new pump and start the mounting bolts by hand.
• Tighten the mounting bolts using a 12mm socket and torque wrench: Torque to 22 N·m (16 ft-lbs).
• Install a new pump inlet O-ring if your pump uses one at the inlet/pipe connection.

Step 7: Reconnect the pressure line with new sealing washers

• Install the pressure fitting/banjo with new sealing washers in the same stack order as removed.
• Tighten using a line wrench and finish with a torque wrench: Torque to 34 N·m (25 ft-lbs).
• Wipe the area clean with shop rags so you can spot leaks later.

Step 8: Reconnect the return hose

• Push the return hose fully onto the pump nipple.
• Use hose clamp pliers to move the clamp back into its original position.

Step 9: Reinstall and tension the belt

• Route the belt back onto the pulley.
• Use a 12mm socket to turn the adjuster and set belt tension.
• Tighten the lock/pivot bolts with a 12mm socket and torque wrench: Torque to 44 N·m (32 ft-lbs).

Step 10: Refill and bleed the power steering system

• Fill the reservoir to the MAX line using Honda-compatible power steering fluid and a funnel.
• With the engine OFF and front wheels off the ground (recommended), slowly turn the steering wheel left-to-right about 10 times.
• Check the reservoir and top off as needed.
• Reconnect the battery negative cable using a 10mm wrench.
• Start the engine and let it idle; turn the wheel slowly lock-to-lock 3–5 times without holding at the stops.
• Shut the engine off, recheck fluid level, and top off to the correct mark.

✅ After Repair

• With the engine idling, inspect the pressure fitting and return hose for any leaks.
• Listen for whining; mild noise can happen until all air is purged.
• Test drive in a parking lot and confirm smooth steering assist in both directions.
• Recheck the fluid level after the test drive and again the next day.
