why does my Ford Mustang S550 (2015-2023) make a whining noise

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shocks.

2. Inspect and Top Off Power Steering Fluid

• Locate the power steering reservoir.
• Open the cap and check the fluid level; if low, add fluid to the recommended level using the correct type (usually ATF or specific power steering fluid).
• Start the engine and turn the steering wheel from lock to lock to purge any air.

3. Replace Serpentine Belt

• Use a socket or wrench to relieve tension on the serpentine belt tensioner.
• Remove the old belt and inspect all pulleys for damage.
• Install the new serpentine belt according to the routing diagram.
• Ensure proper tension is applied; the belt should not be overly tight.

4. Check Differential and Transmission Fluid

• For the differential, remove the fill plug and check fluid level; if low, add the manufacturer-recommended fluid until it reaches the fill hole.
• For the transmission, check fluid level using the dipstick if applicable; add fluid as necessary, ensuring it is the correct type (often Mercon LV for Ford vehicles).
