my Toyota RAV4 XA40 (2013-2018) has a warning light and no power steering, what's wrong?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, screwdrivers, fluid catch pan, power steering fluid.
• Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is on a flat surface and the engine is cool.

2. Address Fluid Issues

• Inspect Fluid Level:

  • Locate the power steering reservoir.
  • Check the fluid level; if low, top off with the manufacturer-recommended power steering fluid.

• Check for Leaks:

  • Inspect hoses and connections for any signs of leakage.
  • Replace any damaged hoses or clamps.

3. Inspect and Replace the Power Steering Pump

• Remove the Old Pump:

  • Disconnect the power steering pump belt.
  • Disconnect the fluid lines from the pump (use a fluid catch pan to collect any spillage).
  • Remove the mounting bolts securing the pump to the engine.
  • Carefully remove the pump from its position.

• Install New Pump:

  • Position the new power steering pump in place.
  • Secure it with mounting bolts to the specified torque (refer to service manual for torque specs).
  • Reconnect the fluid lines, ensuring they are secure and leak-free.

4. Reinstall the Belt

• Reattach the Power Steering Belt:
  • Ensure the belt is aligned properly on all pulleys.
  • Adjust tension according to specifications.

5. Final Checks

• Bleed the Power Steering System:
  • Fill the reservoir to the recommended level with power steering fluid.
  • Start the engine and turn the steering wheel from lock to lock to remove air from the system.
  • Check fluid level again and top off as necessary.
