Tools & Materials Needed

  • Oil drain pan
  • Socket wrench set
  • New oil filter
  • Recommended engine oil (check your owner's manual for specifications)
  • Funnel
  • Clean rags

Step-by-Step Guide

1. Prepare Your ATV

Ensure your YFZ50 is on a level surface and the engine is cool. This prevents burns and ensures all the old oil drains out completely.

2. Drain the Old Oil

Place the oil drain pan under the engine. Use the socket wrench to remove the drain plug located at the bottom of the engine. Allow the oil to completely drain into the pan. Once drained, replace the drain plug and tighten it securely.

3. Replace the Oil Filter

Locate the oil filter and use the appropriate tool to remove it. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. This ensures a proper seal. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Add New Oil

Using a funnel, pour the recommended amount of new engine oil into the oil fill port. Refer to your owner's manual for the correct oil capacity. After adding oil, replace the oil fill cap securely.

5. Check Oil Level

Start the engine and let it run for a few minutes. Turn off the engine and wait a few minutes for the oil to settle. Use the dipstick to check the oil level, ensuring it is within the recommended range. Add more oil if necessary.
