Tools and Materials Needed

  • Oil drain pan
  • Socket wrench set
  • New oil filter
  • Fresh engine oil (check your owner's manual for the recommended type and amount)
  • Funnel
  • Clean rags

Step-by-Step Guide

1. Prepare Your ATV

Ensure your TRX90 is on a level surface and the engine is warm. This helps the oil drain out smoothly. Turn off the engine and let it cool slightly to avoid burns.

2. Drain the Old Oil

Place the oil drain pan under the engine. Locate the oil drain bolt underneath the ATV. Use a socket wrench to remove the bolt and allow the old oil to completely drain into the pan. Be careful as the oil may still 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 fresh oil to the rubber seal of the new filter. This ensures a proper seal. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Add New Oil

Once the old oil has completely drained, replace the drain bolt and tighten it securely. Use a funnel to pour the recommended amount of fresh oil into the engine. Check the oil level with the dipstick to ensure it is at the correct level.

5. Check for Leaks

Start the engine and let it run for a few minutes. Check around the oil filter and drain bolt for any leaks. If there are no leaks, turn off the engine and recheck the oil level, adding more if necessary.
