Step-by-Step Guide

1. Warm Up the Engine

Start the ATV and let it run for a few minutes. This helps the oil to warm up, making it easier to drain.

2. Locate the Drain Plug

Position your oil drain pan under the engine. Locate the oil drain plug on the bottom of the engine. Use a socket wrench to remove the plug and allow the oil to completely drain into the pan.

3. Replace the Oil Filter

While the oil is draining, locate the oil filter. Use an oil filter wrench 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. Screw the new filter into place by hand until it is snug.

4. Reinstall the Drain Plug

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

5. Add New Oil

Using a funnel, pour the new oil into the engine. The 2002 Honda TRX400 Foreman 4X4 typically requires about 2.3 quarts of oil. Check the oil level with the dipstick to ensure it is at the correct level.

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 signs of leaks. If there are no leaks, your oil change is complete.
