Maintaining optimal engine temperature is crucial for the performance and longevity of your 2012 Husqvarna TXC511. Changing the coolant not only prevents overheating but also safeguards vital engine components from corrosion and buildup. This guide provides proprietary MotoSport instructions tailored to your TXC511, addressing model-specific needs and recommended best practices.

What You Will Need

  • High-quality, silicate-free motorcycle coolant (recommended for aluminum radiators)
  • Drain pan
  • Socket or wrench (for drain plug removal)
  • Distilled water (for flushing)
  • Rubber gloves
  • Clean rags
  • Funnel

Preparation

  • Ensure the bike is entirely cold before beginning. Never open the radiator cap or drain coolant on a hot engine, as pressurized hot coolant can cause burns and injuries. Let the bike cool completely if recently run.
  • Position your TXC511 vertically on a stand so it remains upright for accurate filling and level checks.

Draining the Old Coolant

  • Locate the coolant drain screw on the right side of the cylinder. Place the drain pan directly below this point.
  • First, remove the drain screw. Then, slowly loosen and remove the left radiator cap. This prevents sudden coolant discharge.
  • Allow the coolant to drain completely. Dispose of used coolant responsiblynever pour it down household drains or onto the ground.

Flushing the Cooling System (Recommended)

  • After draining, reinstall the drain screw temporarily.
  • Fill the radiator with distilled water.
  • Reinstall the radiator cap, start the engine, and let it idle until warm (when the fan cycles on or the engine reaches operating temperature). Turn off the engine and let it cool.
  • Drain the water as before. Repeat this step if the drained water is still contaminated or colored.

Adding New Coolant

  • Tighten the drain screw securely.
  • Using a funnel, fill the left radiator with fresh coolant. For the TXC511, ensure the level is approximately 10 mm above the cells inside the left radiator with the engine cold and the bike vertical.
  • Reinstall the radiator cap.

Final Steps – Bleeding Air and Checking Levels

  • Start the engine and let it idle with the radiator cap ON until it warms up. This allows the thermostat to open, circulating coolant.
  • Shut off the engine, let it cool, then recheck the coolant level. Top off if necessary – proper level should be maintained above the radiator core but below the cap neck.
  • Check for leaks at the drain screw, hose clamps, and around the radiator cap area.

Important Notes Specific to the 2012 TXC511

  • This engine utilizes aluminum radiators, so use only silicate-free coolant to prevent internal abrasion and extend cooling system life.
  • Regularly check coolant level via the sight glass on the left radiator and maintain with the motorcycle upright.
  • Change coolant every two years or after extensive off-road use for best protection.
  • Inspect hoses and the cap for wear and replace if necessary to avoid future leaks or pressure issues.
  • Dispose of all used fluids according to local environmental regulationsnever dump coolant onto the ground.

Proper coolant replacement not only guards your investment in the TXC511 but also ensures peak performance on every ride. If you need parts or upgrade components for your cooling system, MotoSport makes it easy—Shop parts for a 2012 Husqvarna TXC511 Dirt Bike.
