Tools and Materials Needed

  • Oil filter
  • 4-stroke engine oil (10W-40 recommended)
  • 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 warms up the oil, allowing it to drain more easily. Be sure to turn off the engine before proceeding to the next step.

2. Locate the Drain Plug

The 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. This may take a few minutes.

4. 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 gasket on the top of the filter. This ensures a proper seal. Install the new filter by hand, tightening it securely.

5. Reinstall the Drain Plug

Once the oil has completely drained, reinstall the drain plug. Ensure it is tightened securely to prevent leaks.

6. Add New Oil

Using a funnel, pour the new 10W-40 engine oil into the oil fill port. The 2000 Honda TRX400EX typically requires about 2 quarts of oil. Check the owner's manual for the exact capacity. After adding the oil, 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 you notice any, turn off the engine and tighten the components as needed.
