Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is cool. This prevents burns and ensures accurate oil drainage.

2. Locate the Drain Plug

The drain plug is located at the bottom of the engine. Use a socket wrench to loosen and remove the plug, allowing the old oil to drain into the pan. Be cautious of hot oil.

3. Remove the Oil Filter

Using the appropriate tool, remove the old oil filter. Be prepared for some oil spillage. Clean the area around the filter mount with a rag.

4. Install the New Oil Filter

Apply a small amount of new oil to the rubber gasket of the new filter. Install the filter by hand, ensuring it is snug but not overtightened.

5. Reinstall the Drain Plug

Once the oil has completely drained, reinstall the drain plug securely. Avoid overtightening to prevent damage to the threads.

6. Add New Oil

Using a funnel, pour the recommended amount of new oil into the engine. The 1990 Suzuki LT250S typically requires about 2 quarts. 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 for any leaks around the oil filter and drain plug. If leaks are present, tighten as needed.

8. Dispose of Old Oil Properly

Take the used oil and filter to a recycling center or an auto shop that disposes of oil responsibly.
