The cooling system in your 2012 Husqvarna TE511 is vital for keeping your te511 performing at its peak, especially under tough off-road conditions. Performing a coolant change is straightforward, but following the right steps is crucial to ensure proper function and longevity of your engine. Here is MotoSport's proprietary step-by-step guide specifically for your TE511, including essential model-specific tips.

Preparation: Tools & Supplies Needed

  • Fresh coolant (use only high-quality, motorcycle-approved coolant)
  • Distilled water (if mixing concentrate)
  • Basic hand tools (socket wrench, screwdrivers)
  • Drip pan
  • Protective gloves & rags
  • Funnel

Step 1: Ensure Engine is Cool & Position the Bike

  • Allow the engine to cool completely before starting. The TE511's radiators are positioned high – hot coolant can cause severe burns.
  • Stand the bike vertically on a level surface for accuracy when checking and filling coolant.

Step 2: Locate Drain Screw & Radiator Cap

  • Place your drip pan under the right-hand side of the cylinder where the coolant drain screw is located.
  • FIRST, remove the drain screw. THEN, slowly open the left radiator cap to vent the system and allow coolant to drain completely.

Step 3: Drain Old Coolant

  • Let the old coolant drain fully into your drip pan. Inspect its color – any signs of rust or debris may indicate a need for system cleaning or inspection.
  • Close and tighten the drain screw after draining. Consider installing a fresh sealing washer to prevent leaks.

Step 4: Refill with Fresh Coolant

  • Use a funnel to fill the radiator with the recommended fresh coolant. If using concentrate, mix only with distilled water to avoid mineral buildup in the TE511's delicate radiator fins.
  • Fill until the coolant is approximately 10 mm (0.39 in) above the cells inside the left radiator, with the bike upright and engine cold.

Step 5: Burp the Cooling System

  • With the radiator cap still off, start the engine and let it idle for a few minutes. Gently blip the throttle and carefully rock the bike side-to-side to help air bubbles escape.
  • Shut off the engine, let it cool, and check the coolant level again. Top off as needed, then secure the radiator cap.

Step 6: Check & Top Off Coolant Reservoir

  • Fill the expansion tank (if equipped) to the upper line as specified in your owner's manual.

Step 7: Final Inspection

  • After your first few rides, let the TE511 cool and inspect coolant level. Air may purge out over the first couple heat cycles, requiring a quick top-off.
  • Inspect for any drips or leaks at the drain screw and radiator cap.

2012 Husqvarna TE511 Owner Notes

  • This model's high-compression single-cylinder engine makes proper cooling especially critical under hard riding or racing.
  • The radiators are compact and efficient – always ensure the cooling fins are clean and unobstructed for optimal airflow.
  • Never use regular tap water, as mineral content can quickly clog the narrow cooling passages.
  • Check coolant level at the left radiator with the bike vertical & engine cold, as per the factory specification.

Changing coolant is essential maintenance that keeps your TE511 at its best, letting you focus on the ride ahead – not overheating. For factory-approved coolant, sealing washers, and replacement radiators, MotoSport has you covered.
