Tools & Materials Needed

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

Step-by-Step Guide

1. Warm Up the Engine

Start the engine and let it run for a few minutes. This helps the oil to warm up, making it easier to drain. Ensure the ATV is on a level surface and turn off the engine before proceeding.

2. Locate the Drain Plug

The oil drain plug is located on the bottom of the engine. Place the oil drain pan underneath to catch the old oil.

3. Remove the Drain Plug

Using a socket wrench, carefully remove the drain plug. Allow the old oil to completely drain into the pan. Be cautious as the oil may be hot.

4. Replace the Oil Filter

While the oil is draining, locate the oil filter. Remove the old filter using an appropriate tool. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Install the new filter by hand, ensuring it is snug but not overtightened.

5. Reinstall the Drain Plug

Once the oil has fully drained, reinstall the drain plug. Tighten it securely with the socket wrench, but avoid overtightening to prevent damage.

6. Add New Oil

Using a funnel, pour the recommended amount of new oil into the engine. The 2005 Honda TRX250EX typically requires about 1.6 quarts. Check the oil level with the dipstick and add more if necessary.

7. Check for Leaks

Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any signs of leaks. If there are no leaks, turn off the engine and check the oil level again, topping off if needed.
