Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Serpentine Belt

• Tools Required: Socket set, belt tensioner tool, torque wrench
• Remove the engine cover if applicable.
• Locate the serpentine belt tensioner and use the belt tensioner tool to relieve tension.
• Remove the serpentine belt from the pulleys.
• Inspect the belt for cracks, fraying, or glazing.
• If damaged, replace with a new serpentine belt, ensuring it is routed correctly around all pulleys.
• Reapply tension and check alignment.

3. Check and Replenish Fluids

• Tools Required: Fluid pump, funnel
• Inspect transmission fluid level using the dipstick while the engine is running.
• If low, add the appropriate type of transmission fluid as specified in the service manual.
• Check the differential fluid level and add fluid if necessary.
• Inspect and top up the power steering fluid if needed.

4. Inspect Power Steering System

• Tools Required: None
• Visually inspect power steering hoses for leaks or damage.
• If there are leaks, replace the affected hoses and refill the power steering fluid.
• If the pump is noisy after fluid replacement, consider replacing the power steering pump.
