Regular coolant changes are critical for engine performance, reliability, and temperature regulation on the Husqvarna 701 Supermoto. This model uses a modern liquid-cooled single-cylinder engine and has specific maintenance requirements that every owner should note. Follow these proprietary MotoSport instructions to safely and effectively change the coolant on your 2019 Husqvarna 701 Supermoto.

Items Needed

  • Correct specification coolant (look for silicate-free, motorcycle-specific coolant)
  • Drain pan
  • 10mm socket or wrench
  • Funnel
  • Clean rag
  • Protective gloves & eyewear

Preparation

  • Make sure the engine is completely cool to the touch to avoid burns from hot coolant.
  • Park the motorcycle on a stable surface using the side stand.
  • Remove the seat and left side panel if necessary for easy access to the radiator cap and reservoir.

Draining the Old Coolant

  • Locate the coolant drain bolt on the lower right side of the engine cover.
  • Place the drain pan under the drain bolt.
  • Slowly open the radiator cap to break the system's vacuum seal, allowing coolant to flow freely.
  • Loosen and fully remove the coolant drain bolt with your 10mm tool.
  • Allow the coolant to drain completely. Opening the reservoir cap speeds up draining.

Flushing (Optional, Recommended)

  • If the coolant is contaminated or has not been changed in more than 2 years, flush the system with distilled water before refilling.
  • Replace the drain bolt and tighten it securely after flushing.

Filling with New Coolant

  • With the drain bolt in place, pour the specified amount of new coolant directly into the radiator. Fill until it is just below the bottom of the filler neck.
  • Also fill the compensating (expansion) tank to the "MIN" to "MAX" marks.
  • Replace the radiator and reservoir caps securely.

Removing Air from the System

  • Start the motorcycle and let it idle until it reaches normal operating temperature. This helps circulate coolant and purge air from the system.
  • Once the radiator fan cycles on, shut off the engine and let it cool completely back to ambient temperature.
  • After cooling, check and top off both the radiator and the expansion tank as needed. Reinstall all body panels and hardware.

Key Notes for 701 Owners

  • This model holds approximately 1.2-1.3 quarts (1.1-1.2 liters) of coolant. Always check your owner's manual for the exact volume.
  • The 701's high-performance engine runs hotter than some dirt bikes’ engines, making correct coolant level and quality paramount.
  • Never mix different coolant types (e.g., silicated automotive and motorcycle coolant), as it may reduce system performance or cause deposits.
  • If you notice the reservoir level dropping repeatedly or find milky residue, this could indicate a leak or head gasket issuecontact a Husqvarna technician.
  • Recheck coolant levels after your next ride for any trapped air that may have purged.
