Shop parts for a 2017 Husqvarna TE300 Dirt Bike.

The 2017 Husqvarna TE300 is a championship-proven enduro machine built to thrive in punishing real-world conditions. Routine maintenance like a coolant change is one of the simplest ways to keep this 2-stroke running reliably and to protect your investment. Below, you'll find everything you need to know, with specific tips unique to the 2017 TE300 platform.

What Makes the TE300's Cooling System Unique?

  • The TE300 uses parallel dual radiators that connect at the top and bottom, meaning coolant is distributed evenly across both sides. This ensures efficient engine temperature controlgreat for tight, technical trails but demanding for the cooling system.
  • It is originally filled from the factory with a blue, G11-spec antifreeze, which is a standard, phosphate-free European coolant offering aluminum component compatibility and robust anti-corrosion properties. Always use a recommended coolant type or a reputable motocross racing coolant for best results.

Preparation – Tools and Supplies

  • 3mm, 6mm Allen/hex wrench
  • Drain pan
  • Funnel
  • Rags or paper towels
  • New coolant (OE blue G11 or motocross-specific)
  • Distilled water (if diluting concentrate)
  • Torque wrench (recommended for reinstalling drain bolt)
  • Safety gloves

Step 1: Cool Down and Prep

  • Park the bike on a stable stand and make sure the engine is completely cool before starting. Coolant under pressure can cause burns.
  • Remove the front shrouds or panels as needed for radiator access (consult your owner's manual for quick shroud removal if you're unfamiliar).

Step 2: Access and Open the Radiator Cap

  • Locate the radiator cap on the right-hand side, just behind the front number plate.
  • Twist the cap off slowly to release any residual pressure.

Step 3: Remove the Coolant Drain Bolt

  • The coolant drain bolt is located on the right side of the engine, just above the power valve cover. It will have a copper or aluminum sealing washer.
  • Place your drain pan beneath this position and remove the bolt carefully. Coolant will flow outallow it to drain fully from both radiators for a complete change.

Step 4: Flush (Optional but Recommended)

  • If the coolant is dirty, you can flush the system by pouring clean distilled water through the radiator neck with the drain bolt out. Allow it to drain completely to prevent mixture of old and new coolant.

Step 5: Reinstall the Drain Bolt

  • Reinstall the drain bolt with a new sealing washer if needed. Tighten to OE torque specsdo not overtighten as this can strip the threads.

Step 6: Add New Coolant

  • Using a funnel, slowly pour the new coolant into the radiator until full. On these models, the radiator is filled completely until the level just reaches the bottom of the neck with the bike upright.
  • Allow the bike to settle, then "burp" air from the systemgently rock the bike side to side, top off again if needed. Check coolant level in the overflow bottle as well.

Step 7: Check for Leaks and Final Top-Off

  • Start the engine and let it idle for a minute with the radiator cap off. Watch for air bubbles as trapped air escapes. Top up coolant if the level drops.
  • Replace the radiator cap. Inspect for leaks at the drain bolt and hose connections.

2017 TE300 Special Tips

  • Mixing old coolant types may cause chemical reactions—when in doubt, fully flush the system with distilled water before refilling with new coolant.
  • Check for radiator fin damage or debris at every coolant change for optimal cooling performance.
  • Overheating is rare but possible, especially in slow-going technical rides. Consider a radiator fan kit or higher-performance coolant for added protection.

How Often Should You Change Coolant?

  • For hard enduro use or high-hour riding, change coolant at least once per season or every 12 months–whichever comes first.
  • Always inspect for loss through the overflow or unusual color/smell—these can indicate system leaks or head gasket concerns.
