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 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. Remove the Drain Plug

Locate the oil drain plug underneath the engine. Place the oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old 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. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Reinstall the Drain Plug

Once the oil has completely drained, reinstall the drain plug. Tighten it securely with the socket wrench, but be careful not to overtighten and strip the threads.

5. Add New Oil

Using a funnel, pour the new 10W-40 engine oil into the oil fill cap located on the top of the engine. Refer to your owner's manual for the exact oil capacity, but it is typically around 2.3 quarts for this model. Check the oil level with the dipstick and add more if necessary.

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, turn off the engine and check the oil level again, adding more if needed.
