Tools and Materials Needed

  • Socket set
  • Drain pan
  • Funnel
  • New oil filter
  • 4-stroke engine oil (check your manual for specifications)

Step-by-Step Guide

1. Warm Up the Engine

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

2. Locate the Drain Plug

Position your drain pan under the engine. Locate the oil drain plug on the bottom of the engine and use a socket wrench to remove it. Allow the old oil to completely drain into the pan.

3. Remove the Oil Filter

Using an oil filter wrench, carefully remove the old oil filter. Be prepared for some oil to spill out when you remove it.

4. Install the New Oil Filter

Before installing the new oil filter, apply a small amount of new oil to the rubber gasket on the top of the filter. This ensures a good seal. Screw the new filter into place by hand until it's snug, then tighten it an additional quarter turn with the wrench.

5. Replace the Drain Plug

Once all the old oil has drained, replace the drain plug and tighten it securely with the socket wrench.

6. Add New Oil

Using a funnel, pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. After adding the oil, check the 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 you notice any, tighten the components as needed.
