Changing the oil in your 1989 Honda TRX350 4X4 is a crucial maintenance task that ensures your ATV runs smoothly and efficiently. Follow these steps to perform an oil change on your TRX350:

Tools and Materials Needed

  • Oil filter wrench
  • Socket set
  • Drain pan
  • Funnel
  • New oil filter
  • 4-stroke engine oil (check your manual for the correct type)
  • Rags or paper towels

Step-by-Step Guide

1. Prepare Your ATV

Ensure your TRX350 is on a level surface and the engine is cool. This will prevent burns and ensure accurate oil drainage.

2. Drain the Old Oil

Locate the oil drain plug underneath the engine. Place the drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. Once drained, replace and tighten the drain plug securely.

3. Replace the Oil Filter

Use the oil filter wrench to remove the old oil 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.

4. Add New Oil

Remove the oil fill cap located on the top of the engine. Using a funnel, pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. Once filled, replace the oil fill cap.

5. Check Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a couple of minutes for the oil to settle. Check the oil level using the dipstick and add more oil if necessary to reach the recommended level.
