Symptoms

•Whining noise occurs while turning the steering wheel
•Noise may increase in volume with sharper turns
•Possible difficulty in steering or a feeling of resistance
•Fluid leaks around the power steering reservoir or lines
•Steering wheel may feel stiffer than usual

Diagnostic Steps

1
Inspect Power Steering Fluid Level: Check the power steering fluid level in the reservoir to ensure it is at the correct level.
2
Look for Fluid Leaks: Examine the area around the power steering pump, hoses, and rack and pinion for any signs of leaking fluid.
3
Listen for Noise Source: With the vehicle running, have someone turn the steering wheel while you listen closely to identify if the noise is coming from the power steering pump or another component.
4
Check Power Steering Pump: Inspect the power steering pump for any visible damage or wear signs, and check the pulley for proper alignment.
5
Examine Steering Rack and Pinion: Conduct a visual inspection of the steering rack and pinion for any damage or play.
6
Inspect Serpentine Belt: Check the condition of the serpentine belt for wear or looseness, as it drives the power steering pump.

Solution

1. Preparation

Tools Required: Socket set, wrench set, power steering fluid, drip pan
Ensure the vehicle is parked on a flat surface and the engine is off before starting any work.

2. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the markings on the reservoir.
3. If low, add the appropriate type of power steering fluid recommended by Honda.
4. Replace the cap securely.

3. Repair or Replace Leaking Components

Sub-steps:
1. If leaks are found, determine the source (hoses, pump, or rack).
2. If a hose is leaking, disconnect it using a wrench, and then replace it with a new one.
3. For a leaking power steering pump, disconnect the power steering lines, remove the pump using a socket set, and replace it with a new pump.
4. For a damaged steering rack, remove it following manufacturer procedures and install a new steering rack.

4. Inspect and Replace Serpentine Belt (if necessary)

Sub-steps:
1. Inspect the serpentine belt for cracks or excessive wear.
2. If replacement is needed, loosen the tensioner using a wrench and remove the old belt.
3. Install the new serpentine belt according to the belt routing diagram typically found on the engine bay.
4. Re-tension the belt and ensure it is properly aligned on all pulleys.
