Tools and Materials You’ll Need

  • Motorcycle stand or lift (to stabilize the bike)
  • Socket set (especially 8mm, 10mm, 17mm sockets)
  • Wrench set
  • Oil filter wrench (optional, but helpful)
  • Clean drain pan
  • New oil filter
  • 4-stroke engine oil (10W-40 recommended, check manual for exact spec)
  • Funnel
  • Shop rags or paper towels
  • Gloves
  • Torque wrench

Step-by-Step Oil Change Procedure

  • Prepare Your Workspace:– Place your TE250 on a stand so it remains upright and stable throughout the process. Work in a well-ventilated area with plenty of light.
  • Warm Up the Engine:– Start the bike and let it idle for a few minutes to warm the oil. Warm oil flows more easily and helps carry away contaminants. Shut off the engine before proceeding.
  • Remove the Oil Drain Bolt:– Locate the oil drain bolt on the underside of the engine case. Place your drain pan beneath it. Using a 17mm socket, loosen and remove the drain bolt, allowing the old oil to drain completely. Be careful, as the oil may be hot. Inspect the drain bolt washer for wear; replace if necessary.
  • Remove and Replace the Oil Filter:– After the oil has drained, locate the oil filter cover (usually on the left side of the engine). Remove the cover with the appropriate socket or wrench. Take out the old oil filter, being careful not to spill residual oil. Clean the filter housing and the sealing surface. Install the new filter, ensuring the O-ring is seated properly. Reinstall the cover and tighten to the manufacturer’s specification.
  • Clean and Reinstall the Drain Bolt:– Wipe the drain bolt and the sealing surface on the engine case. Install the drain bolt with a new washer if needed, and tighten to the recommended torque (typically about 15–20 Nm, but check your manual for the exact value).
  • Add New Engine Oil:– Locate the oil filler cap on the engine. Insert a funnel and pour in the correct amount of fresh oil—typically about 0.85 liters (0.9 quarts) for a TE250, but always check your owner’s manual for your specific year and for the oil you are using. Do not overfill, as this can cause engine damage.
  • Check the Oil Level:– After adding oil, start the engine and let it idle for a minute to circulate the new oil. Shut off the engine and wait a minute for the oil to settle. Remove the oil level check screw (if equipped) or check the dipstick to ensure the oil level is within the recommended range. Adjust by adding or draining small amounts as needed.
  • Inspect for Leaks:– With the engine off, look carefully around the drain bolt and oil filter cover for any signs of leakage. Tighten if necessary.
  • Clean Up and Dispose of Old Oil Properly:– Wipe down any spilled oil and collect all used oil and filters for proper recycling.

Model-Specific Call-Outs

The 2004 Husqvarna TE250 is a 4-stroke enduro bike with a shared-sump engine, meaning engine oil lubricates both the engine and transmission. Use a high-quality 10W-40 4-stroke motorcycle oil that is JASO MA rated for wet clutches–check your manual for the exact specification.

Unlike some later Husqvarna models, the 2004 TE250 does not have a separate gear oil reservoir; everything is lubricated by the engine oil. Therefore, you only need to change the engine oil and filter, not any separate transmission oil.

Oil capacity is typically around 0.85 liters (0.9 quarts) for an oil change with a new filter, but always confirm with your owner’s manual. Overfilling can lead to excessive crankcase pressure and oil leaks. Underfilling can result in insufficient lubrication and engine damage.

The oil filter is a cartridge type, so you’ll need to remove the oil filter cover to access it. Always use a new O-ring and ensure it is seated correctly to avoid leaks. Torque specifications are critical—overtightening can strip threads, and undertightening can cause leaks.

If you do not have a manual or are unsure about any steps, Husqvarna provides downloadable owner’s and service manuals for many models on their official website. Double-check your manual if you are uncertain about capacities, oil types, or procedures.

Finally, Husqvarna engines are precision machines and benefit from regular maintenance. Change your oil and filter at least every 15 hours of operation or as specified in your manual, whichever comes first–more often if you ride in dusty or demanding conditions.
