  • Socket wrench set

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. Turn off the engine and ensure the ATV is on a level surface.

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 and replace it with a new one. Make sure to lubricate the rubber gasket on the new filter with a bit of new oil before installing it.

5. Reinstall the Drain Plug

Once the oil has fully drained, reinstall the drain plug securely. Ensure it is tightened to the manufacturer's specifications to prevent leaks.

6. Add New Oil

Using a funnel, pour the new oil into the engine. The 2003 Honda TRX90 typically requires about 1 quart of 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 there are no leaks, your oil change is complete.
