Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Sub-step 1: Remove the power steering fluid reservoir cap.
Sub-step 2: Check the fluid level and color; if dark or contaminated, proceed to replace.
Sub-step 3: Using a siphon pump, remove old fluid from the reservoir and replace it with new power steering fluid (check owner's manual for the correct fluid specification).
Tools Required: Siphon pump, funnel.

3. Check and Replace Power Steering Pump

Sub-step 1: If the fluid was low or contaminated, inspect the power steering pump for damage.
Sub-step 2: Disconnect the power steering lines from the pump and remove the mounting bolts.
Sub-step 3: Install the new power steering pump, ensuring all connections are tight.
Sub-step 4: Reconnect the power steering lines and torque to manufacturer specifications.
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Serpentine Belt (if needed)

Sub-step 1: Locate the tensioner and relieve tension on the serpentine belt.
Sub-step 2: Remove the old belt and compare it with the new one for correct size.
Sub-step 3: Install the new serpentine belt, ensuring it is routed correctly around pulleys.
Sub-step 4: Reapply tension using the tensioner and check for proper alignment.
Tools Required: Serpentine belt tool, socket set.
