  • Inspect your tires as well. Uneven tread can cause some noise when driving over bumpy terrain. Worn-out tires can also be a source of sloshing sounds.
  • Open up your car hood and look around the engine compartment. A sloshing sound can often come from something as simple as low fluid levels or worn-out belts.

Step-by-Step Processes for How to Fix Sloshing Sound in Car 

Step 1: Inspect Your Car

Take a look around your car and identify if you can see any signs of damage that might be causing the sloshing sound. Check for any oil leaks, loose or broken parts, or any other issues.

Low levels in any of these fluids can cause various problems, so it is important to ensure they are topped up.

Step 5: Change Your Oil

If your car is overdue for an oil change, this could also be causing the sloshing sound. Make sure to follow your manufacturer’s instructions for changing the oil and use the correct type of oil for your vehicle.
