Routine coolant changes are critical to keeping your 2016 Husqvarna TE125 running strong, preventing overheating, and protecting the engine’s internal components from corrosion and scale build-up. The following MotoSport guide is tailored specifically to your TE125, highlighting important technical notes along with the step-by-step process.

What Makes the 2016 TE125 Unique?

The 2016 TE125 is a lightweight, competition-ready enduro bike featuring a high-performance two-stroke engine and liquid cooling system. The cooling capacity is approximately 1.2 liters (1.3 quarts) of coolant, making it essential to use the correct amount and type of coolant for optimal performance.–2

Preparation: What You Need

  • Fresh motorcycle coolant (consult your manual for recommended spec – avoid mixing types)
  • Distilled water (if mixing your own coolant; do not use tap water to prevent mineral deposits)
  • Socket set and screwdriver
  • Drain pan
  • Clean shop rags
  • New sealing washer or O-ring for the drain bolt
  • Safety gloves and eyewear

Step-by-Step Coolant Change Process

  1. Ensure the engine is cool before starting to avoid burns.
  2. Stabilize the bike upright using a stand for level draining and filling.–2
  3. Remove the seat and right-side shrouds for easier access to the radiator cap and drain bolt.
  4. Place a drain pan under the water pump area (typically on the lower right side of the engine).
  5. Remove the radiator cap to allow air flow and quick draining.
  6. Locate and remove the drain bolt at the lowest point of the water pump cover. Allow old coolant to drain completely.–2
  7. Inspect and replace the sealing washer or O-ring on the drain bolt for a proper seal.
  8. Reinstall and torque the drain bolt once drained.
  9. Fill the radiator with fresh coolant up to the filler neck (1.2 liters). Use only distilled water if required to mix. Do not use tap water as it can cause mineral deposits in the radiator.–1
  10. "Burp" the system: Start the engine briefly (with the radiator cap off), gently rock the bike and blip the throttle to release trapped air bubbles. Shut off the engine and top off the coolant level if necessary.–1
  11. Refit the radiator cap and any removed bodywork. Wipe away any spilled coolant and clean up the work area.
  12. Dispose of old coolant responsibly – never pour it down the drain or onto the ground.

Important Model-Specific Notes for 2016 TE125 Owners

  • The TE125’s compact radiators and narrow passageways mean air can get trapped more easily—the burping step is especially crucial for this model.
  • Using coolant types not intended for two-stroke engines can cause premature wear or foaming; always conform to recommended specs in your owner’s manual.
  • If riding in extreme temperatures, monitor coolant levels more frequently and consider coolants with antifreeze properties befitting your climate.

Safety Tips

  • Coolant is toxic—keep away from pets and children.
  • If coolant contacts skin or eyes, flush area immediately with plenty of water.–5
  • Change any clothing soaked by coolant to prevent irritation.–5
