Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is warm. This helps the oil drain out smoothly. Turn off the engine and remove the key for safety.

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. Be cautious as the oil may be hot.

3. Replace the Oil Filter

While the oil is draining, locate the oil filter. Use the appropriate tool to remove the old filter. Before installing the new filter, apply a small amount of new oil to the rubber seal of the filter. Install the new filter by hand, ensuring it is snug but not overtightened.

Once the old oil has drained, replace the drain plug securely. Use a funnel to pour the new oil into the engine. The 2003 Honda TRX250EX typically requires about 1.6 quarts of oil. Check the oil level with the dipstick and add more if necessary.
