why does my Toyota RAV4 Fifth Generation (2019-present) have a hard steering feel when cold

Solution

1. Preparation

• Gather the necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Safety: Disconnect the battery before working on the power steering system.

2. Check Fluid Level

• Locate the power steering reservoir.
• Remove the cap and check the fluid level against the dipstick.
• If low, add the recommended power steering fluid (typically ATF or specific PS fluid).
• Inspect fluid for color and clarity; it should be clean and not dark or contaminated.

3. Inspect Power Steering Pump

• Visually inspect the power steering pump for any signs of leaks or damage.
• If leaks are found, replace the power steering pump.
• Disconnect the fluid lines and remove the pump using a socket set; be sure to note the routing of any hoses.

4. Inspect Power Steering Belt

• Check the power steering belt for wear, cracks, or fraying.
• Ensure it is properly tensioned; if not, adjust tension or replace the belt if worn.

5. Pressure Testing

• Install a power steering pressure gauge to the pump outlet.
• Start the engine and let it idle; check the pressure readings against specification (typically 900-1200 PSI).
• If pressure is low, further inspection of the pump or steering gear may be necessary.

6. Reassembly

• If all components are in good condition, reassemble any removed parts.
• Fill the power steering reservoir to the correct level.
• Reconnect the battery and test drive the vehicle to ensure proper operation.
