🔧 Sedona - Power Steering Pump Replacement

You’ll remove the drive belt, disconnect the power steering lines, and swap the pump, then refill and bleed the system. This matters because a worn/leaking pump can cause whining, hard steering, and fluid loss that can damage the new pump if not bled correctly.

Difficulty Level: Advanced | Estimated Time: 2.5-4.5 hours

Assumption: Your Sedona has hydraulic power steering (belt-driven pump), not electric assist.

⚠️ Safety & Precautions

• 🛑 Work on a cool engine; keep hands clear of the belt drive.
• 🧯 Power steering fluid is flammable—keep away from sparks and hot exhaust.
• 🧤 Wear gloves and safety glasses; fluid can irritate skin/eyes.
• 🧱 Support the van with jack stands on solid ground; never rely on a jack alone.
• 🔋 Battery disconnect is recommended if you’ll be working near the alternator main cable.

📋 Before You Begin

• 🅿️ Park on level ground, set the parking brake, and chock the rear wheels.
• 🔧 Raise the front and support it on jack stands so the front wheels can turn freely during bleeding.
• 🧽 Clean around the pump/hoses before opening the system to keep dirt out.
• 🔋 Disconnect the negative battery terminal using a 10mm socket.
• 🧴 Use a turkey baster or fluid transfer pump (specialty) to remove as much fluid as possible from the reservoir into a drain pan.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover/air ducting (as equipped)

• Remove clips/bolts using a flat blade screwdriver and 10mm socket.
• Set parts aside in order. Take a quick photo first.

Step 2: Relieve belt tension and remove the serpentine belt

• Locate the automatic belt tensioner on the front of the engine.
• Use a serpentine belt tool (specialty) or breaker bar 1/2" drive to rotate the tensioner and slip the belt off the power steering pump pulley.
• Remove the belt fully and inspect it; if cracked/glazed, replace it.

Step 3: Place a drain pan and disconnect the return hose

• Position a drain pan under the pump area.
• Use hose clamp pliers to move the clamp back on the return hose.
• Twist/pull the hose off the pump/reservoir nipple carefully and let it drain.
• Plug the hose with a clean rag to reduce dripping.

Step 4: Disconnect the high-pressure line from the pump

• Clean the fitting area with shop rags.
• If your pump uses a flare fitting: Use the correct line wrench to loosen the pressure line fitting, then remove it by hand.
• If your pump uses a banjo bolt: Use the correct socket to remove the banjo bolt and discard the old sealing washers.
• Cap/cover open lines to keep dirt out.

Step 5: Remove the pump pulley (if required for access)

• Install a pulley puller/installer set (specialty) on the pulley.
• Use the puller to remove the pulley straight off the shaft.
• Do not pry on the pulley.

Step 6: Unbolt and remove the power steering pump

• Remove the pump mounting bolts using the appropriate socket and ratchet.
• Support the pump with one hand as you remove the last bolt.
• Lift the pump out carefully, watching for remaining fluid.

Step 7: Transfer parts and install the new pump

• If your new pump does not include a reservoir/pulley, transfer required items from the old pump.
• Set the new pump into place and hand-thread all mounting bolts to avoid cross-threading.
• Tighten mounting bolts with a torque wrench: Torque to 30 Nm (22 ft-lbs).

Step 8: Reinstall the pulley (if removed)

• Use the pulley puller/installer set (specialty) in installer mode to press the pulley on straight.
• Install until the pulley aligns with the other accessory pulleys.
• Misalignment will shred the belt.

Step 9: Reconnect the high-pressure line and return hose

• Flare fitting type: Start threads by hand, then tighten with a line wrench. Torque to 27 Nm (20 ft-lbs).
• Banjo bolt type: Install new sealing washers on both sides of the banjo fitting. Tighten with a torque wrench: Torque to 44 Nm (32 ft-lbs).
• Reconnect the return hose and position the clamp using hose clamp pliers.

Step 10: Reinstall the serpentine belt

• Route the belt using the under-hood belt routing diagram.
• Rotate the tensioner using the serpentine belt tool (specialty) and slip the belt onto the last pulley.
• Visually confirm the belt is fully seated in every pulley groove.

Step 11: Fill and bleed the power steering system

• Fill the reservoir using a funnel with power steering fluid (PSF-4 equivalent) to the MAX line.
• With the front wheels still off the ground and engine OFF, turn the steering wheel slowly from lock-to-lock 15–20 times.
• Check fluid level and top off as needed.
• Reconnect the battery using a 10mm socket.
• Start the engine and let it idle; do not hold the wheel hard against full lock.
• Turn lock-to-lock 5–10 more times, watching for bubbles/foam in the reservoir.
• If fluid foams, shut off engine, wait 10 minutes, and repeat until clear.

✅ After Repair

• 🧪 With the engine idling, check for leaks at the pressure fitting/banjo and return hose.
• 📏 Recheck fluid level after a short test drive; top off to the correct mark.
• 🔊 A brief light whine can be normal until all air is purged; persistent whine usually means air is still trapped.
• 🧼 Clean spilled fluid off belts and pulleys using shop rags.
