  • Oil drain pan
  • Socket wrench set
  • Funnel
  • Clean rags

Steps to Change the Oil

  1. Warm Up the Engine: Start your ATV and let it run for a few minutes. This helps the oil drain out smoothly by thinning it.
  2. Position the ATV: Place the ATV on a level surface and turn off the engine. Ensure the ATV is stable and won't tip over during the process.
  3. Drain the Old Oil: Locate the oil drain plug under the engine. Place the oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain out.
  4. Replace the Oil Filter: Use the wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Screw the new filter into place by hand until it's snug.
  5. Refill with New Oil: Replace the drain plug securely. Using a funnel, pour the new oil into the oil fill cap located on the engine. The 2003 Suzuki LTZ400 typically requires about 2.2 quarts of oil. Check the oil level with the dipstick and add more if necessary.
  6. Check for Leaks: Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any leaks. Tighten if necessary.
  7. Dispose of Old Oil: Properly dispose of the old oil and filter at a recycling center or an auto shop that accepts used oil.
