Troubleshooting Loss of Power Steering Assist in Volvo XC60 (2008-2017)

Loss of power steering assist can lead to difficulty steering and may pose safety risks. Below, I’ll guide you through the symptoms, diagnostic steps, tools required, and repair instructions to help identify and resolve the issue.

Tools Required

Basic hand tools (socket set, wrenches, screwdrivers)
Power steering fluid (consult owner’s manual for specifications)
OBD-II scanner
Torque wrench
Rags for fluid spills
Funnel
Safety goggles
Gloves

Repair Instructions

Step 1: Refill Power Steering Fluid

If the fluid level is low, top it up with the correct type of power steering fluid.
Recheck for leaks after filling and ensure the fluid circulates properly by turning the steering wheel.

Step 2: Replace Power Steering Pump

If the power steering pump is suspected to be faulty:
1. Disconnect the negative battery terminal to ensure safety.
2. Remove the serpentine belt by using a wrench to relieve tension from the tensioner pulley.
3. Disconnect the power steering fluid lines from the pump (use a catch pan to collect fluid).
4. Remove the mounting bolts for the pump and take it out.
5. Install the new power steering pump, ensuring all bolts are torqued to the manufacturer’s specifications.
6. Connect the fluid lines and reinstall the serpentine belt.

Step 3: Inspect/Replace Serpentine Belt

If the serpentine belt is damaged or worn:
1. Remove the old belt and inspect the belt routing.
2. Install the new serpentine belt, following the correct routing diagram (often found on a sticker in the engine bay).

Step 4: Electrical Component Checks (if applicable)

If your XC60 has electric power steering:
1. Replace any blown fuses related to the steering system.
2. If necessary, check the wiring harness for any signs of damage or corrosion.

Step 5: Clear Codes and Test Drive

After performing any repairs, use the OBD-II scanner to clear any fault codes.
Reconnect the battery terminal and take the vehicle for a test drive to ensure the power steering assist is functioning properly.

Final Note

If the power steering assist issue persists after following these troubleshooting steps, it may indicate a more complex problem requiring professional diagnosis. Always consult your vehicle's service manual for specific details regarding parts and procedures, and consider seeking assistance from a qualified automotive technician if necessary.
