Solution

1. Preparation

• Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, fluid pump.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery if working on electrical components.

2. Inspect and Replace Serpentine Belt (if necessary)

• Sub-steps:
  1. Remove the engine cover if applicable.
  2. Release tension on the serpentine belt using a belt tensioner tool.
  3. Remove the old belt and inspect the pulleys for damage.
  4. Install the new serpentine belt, ensuring it is routed correctly.
  5. Reapply tension and check for proper alignment.
• Safety Warning: Wear gloves and safety glasses while working on engine components.

3. Check and Refill Power Steering Fluid

• Sub-steps:
  1. Locate the power steering fluid reservoir.
  2. Remove the cap and check the fluid level; add the recommended fluid if low.
  3. Inspect power steering lines for leaks and damage.
  4. If leaks are found, replace the affected hoses or the power steering pump.
• Tools Required: Fluid pump for easier fluid transfer.

4. Inspect and Replace Transmission Fluid (if necessary)

• Sub-steps:
  1. Locate the transmission dipstick (if equipped) and check fluid level.
  2. If fluid is low, add the manufacturer-recommended transmission fluid.
  3. If fluid appears burnt or contaminated, drain and replace the transmission fluid using a fluid pump.
  4. Replace the transmission filter if applicable during fluid change.
• Safety Warning: Allow the engine to cool before working on the transmission.
