🔧 Highlander - Power Steering Pump Replacement

On your Highlander, the exact pump/line hardware (and the torque specs) can vary depending on whether you have hydraulic power steering (with a fluid reservoir) or electric power steering (no reservoir). I want to keep this 100% correct for your setup before I walk you through unbolting lines and setting belt tension.

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

⚠️ Safety & Precautions

• ⚠️ Work on a cool engine; hot parts can burn you.
• ⚠️ Use jack stands; never rely on a floor jack alone.
• ⚠️ Power steering fluid is slippery and flammable—wipe spills immediately.
• ⚠️ Keep hands clear of the belt path while rotating the engine by hand.

📋 Before You Begin

• Open the hood and locate the power steering reservoir.
• If you have a reservoir with fluid: plan to drain/suction as much old fluid as possible before disconnecting hoses.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which steering system you have (critical)

• Look for a power steering fluid reservoir with hoses going to a belt-driven pump.
• If there is no reservoir and no pump/hoses, you likely have electric power steering (EPS) and there is no power steering pump to replace.

Step 2: Reply with these two details so I can give exact torque specs + the correct line-removal steps

• Tell me: do you see a power steering fluid reservoir (yes/no)?
• Tell me: does the pressure line attach with a banjo bolt (bolt through a round fitting) or a flare nut (hex nut on the tube)?

Once you confirm those two items, I’ll give the complete, bolt-by-bolt procedure with the correct Toyota torque specs and bleed steps for your Highlander.

✅ After Repair

• After the correct install, you’ll need to refill and bleed air from the system, then check for leaks under pressure.
• You’ll also re-check fluid level after a short test drive and again the next day.
