Changing the oil in your 2019 Husqvarna TC250 is essential for maintaining top engine performance and longevity. Below, you’ll find a proprietary, in-depth guide for MotoSport.com readers, including all tools, model-specific tips, and step-by-step instructions tailored to the 2019 TC250.

Tools and Supplies Needed

  • Socket set (generally 8mm, 13mm, and extensions for easiest access)
  • Ratchet or T-handle wrench
  • Drain pan
  • New engine oil (refer to owner’s manual for grade and quantity–TC250 typically uses 0.8 liters of high-quality two-stroke transmission oil)
  • New crush washer (recommended for the drain bolt)
  • Paper towels or shop rags
  • Oil funnel
  • Contact cleaner (optional, but helps clean up any oil residue)
  • Torque wrench (optional but preferred for reinstalling bolts to spec)

2019 Husqvarna TC250 Oil Change: Step-by-Step Instructions

  1. Start and Warm Up the Engine
    • Start the bike and idle for several minutes to warm the oil, making it thinner and easier to drain.
    • Turn off and securely place the bike on a stand.
  2. Remove Lower Skid Plate Guard (If Installed)
    • Use your socket set to remove the two screws beneath the engine guard.
    • Let the guard swing down or remove it for full access to the drain bolt and area beneath the engine. This makes draining and cleanup much easier specifically on the 2019 TC250, which often has a closely fitted lower guard.
  3. Locate the Drain Bolt
    • The oil drain bolt is low on the right side of the engine. Have your drain pan ready and placed directly beneath the bolt.
  4. Remove the Oil Drain Bolt
    • Use the correct socket (usually 13mm, but verify against your bike) and a ratchet or T-handle wrench to loosen and remove the drain bolt.
    • Be cautious–the oil will flow quickly, and some may splash. Allow the oil to drain completely.
    • Inspect the crush washer; replace if there are any signs of damage or flattening.
  5. Remove the Oil Filler Cap
    • Open the oil fill cap on the top right side of the engine. This allows oil to drain more freely and ensures no vacuum prevents thorough drainage.
  6. (Optional) Clean the Drain Bolt and Area
    • Spray and wipe down the bolt and area around the drain hole if it’s oily or dirty. Clean parts ensure proper torque and help spot potential leaks later.
  7. Reinstall the Drain Bolt
    • After the old oil has finished draining, wipe the area clean, fit a new crush washer on the drain bolt, and reinstall it by hand to prevent cross-threading.
    • Tighten the bolt using a torque wrench to manufacturer specs (typically 15 Nm for Husqvarna TC250; always verify with your model’s manual).
  8. Pour in New Oil
    • Insert a funnel into the oil filler hole and carefully pour in the new oil.
    • The 2019 TC250 typically requires 0.8 liters (or approximately 0.85 quarts) of transmission oil–a commonly used grade is 10W-40, but double check your manual for the latest recommendations.
    • Do not overfill; watch the oil level closely.
  9. Check Oil Level
    • There is a small oil level check screw on the side of the crankcase. Remove this screw–a small amount of oil should trickle out when the bike is level, indicating the proper amount is inside.
    • If no oil drips, add a bit more and recheck. Wipe the area clean and reinstall the check screw once finished.
  10. Reinstall the Engine Guard
    • Once the oil change is complete and there are no leaks, reinstall the skid plate or engine guard by tightening the two bolts previously removed.
  11. Start and Inspect
    • Run the engine for a minute or two, then shut it off and re-check for leaks around the drain bolt and fill/check screws.
    • Reinspect the oil level and top off if needed.

2019 Husqvarna TC250 Model-Specific Tips

  • Drain Access: The TC250, especially the 2019 model, often has a closely fit engine guard or skid plate. Removing or loosening the guard simplifies access and avoids messy spills.
  • Oil Quantity: Always use the correct quantity–0.8 liters for the TC250. More or less can affect clutch performance and gearbox life.
  • Check for Leaks: Owners frequently overlook the crush washer under the drain bolt. Always inspect and replace if needed to avoid drips after your ride.
  • Manual Reference: Refer to your Husqvarna user manual for any model revisions, special torque specs, or potential updates on oil capacity.

Recommended Oil Change Intervals

  • Change the oil every 15 hours of run time, or sooner in muddy, sandy, or racing conditions.
  • Inspect oil for color and metallic particles–dark, gritty oil indicates it’s time to change even sooner.
