Why Regular Oil Changes Matter

Regularly changing the engine oil in your 2010 Husqvarna TE450 is essential to maximize the engine's lifespan and ensure optimal performance. High-stress dirt biking accelerates oil breakdown and contamination, so proper maintenance helps prevent premature engine wear, costly repairs, and degraded performance.

Tools & Supplies Needed

  • Socket wrench set (including 10mm and 13mm sockets, plus a 5mm Allen)
  • Drain pan
  • Oil filter (recommended to use OEM for best performance)
  • Engine oil (check your manual for viscosity; 10W-50 fully synthetic for most conditions)
  • New crush washers (optional, but reduces risks of leaks)
  • Rubber gloves
  • Rags
  • Measuring cup
  • Funnel
  • Contact cleaner (for any spills)
  • Snap ring pliers (helpful for filter cover if needed)
  • Torque wrench
  • Safety glasses

Step-By-Step Oil Change

  1. Warm Up the Engine
    Run your bike in a well-ventilated area for a few minutes. This heats the oil so it drains better and carries more contaminants away.
    Note:– Never attempt an oil change with a hot engine—just warm to the touch, not scalding.
  2. Remove the Skid Plate
    If your TE450 has a skid plate, unbolt and remove it to expose the drain plugs. Your skid plate and any aftermarket items might require different tools.
  3. Clean Around Drain Plugs
    Use a rag or contact cleaner to remove dirt and debris from the drain plugs. This prevents contaminants from entering the engine when unplugging.
  4. Drain the Old Oil
    • Place your drain pan under the engine.
    • The TE450 has multiple drain points: remove the main drain plug (typically M16, under the engine) and the secondary filter plug (M14, on the left side of the engine nearer the front). Use the correct sockets/Allen as required.
    • Remove the oil filler cap to allow the oil to drain more completely.
    • Allow several minutes for all oil to drip out.
  5. Replace the Oil Filter
    • The TE450 has two oil filters: a main filter and a secondary filter located on the side cases.
    • Remove both covers, using snap ring pliers for the spring-clipped cover if needed.
    • Carefully remove each filter, making note of their orientation.
    • Insert new filters, ensuring proper alignment.
    • Replace both filter covers and torque to specification.
    Torque Specs Call-Out:– Use 25 Nm (18.4 ft/lb) for both the drain plug and the main oil filter cover plug. Be extremely careful not to overtighten, especially on the plastic/composite filter plug (M14); overtightening will damage the plug's hex socket and can require replacement. Use a torque wrench for accuracy and longevity.
  6. Install New Crush Washers
    Always replace your crush washers with new ones if you have them. This reduces the chance of oil leaks.
  7. Refit Drain and Filter Plugs
    Thread in the drain plugs and oil filter cover by hand to avoid cross-threading, then use your torque wrench to finish to 25 Nm. Do NOT overtighten; this is critical for long-term durability.
  8. Add New Engine Oil
    • Use a funnel and a measuring cup to fill your TE450 with the specified amount and type of oil.
    • Reference your owner's manual or the oil manufacturer's lookup. For most 2010 Husqvarna TE450s, the capacity is about 1.2 liters (use high-quality 10W-50 synthetic, such as AMSOIL or Motorex) .
    • Pour in slowly, checking the level on the dipstick or sight glass after filling just below the max line.
    • Install the filler cap.
  9. Start the Engine and Leak Check
    • Start the engine and let it idle for 2–3 minutes.
    • Shut it off and inspect all plugs and covers for leaks.
    • Top up the oil if necessary, rechecking the level.
  10. Dispose of Old Oil and Filter Properly
    Take your used oil and filters to a certified recycling facility.
  11. Reinstall Skid Plate
    Refit the skid plate (if equipped) and ensure all fasteners are secure.

Model-Specific Notes for the 2010 Husqvarna TE450

  • Drain and filter plug torque:– Husqvarna specifies 25 Nm (18.4ft/lb) for both. The oil filter plug at the front/side of the engine is composite plastic—overtightening can round out the hex or crack the plug, so use extra caution and always use a torque wrench .
  • Oil specification:– Use high-quality 10W-50 full synthetic oil for best engine protection in dual-sport and off-road use .
  • Dirt ingress:– The TE450's drain and filter plugs sit low and are exposed. Always carefully clean the areas before and after service.

Recommended Oil Capacity & Service Intervals

  • Oil amount:– Approximately 1.2 liters for a full change, filters included.
  • Change interval:– Every 600 miles/10 hours (whichever comes first) under normal use, or more often in race environments.

Quick Tips for Success

  • Allow the oil to fully drain while you inspect and clean your oil screens and filter area.
  • Do not use thread locker on any oil plugs or filter covers unless explicitly recommended by Husqvarna.
  • Keep a log of dates and hours when each oil change is performed.

Conclusion

With the right preparation and care, changing the oil on your 2010 Husqvarna TE450 is a straightforward project any owner can tackle with confidence.
