How to Change the Coolant in a 2022 Husqvarna EE 5

Shop parts for a 2022 Husqvarna EE 5 Dirt Bike.

The 2022 Husqvarna EE 5 is a unique electric dirt bike built with premium race-inspired features, designed for young riders who want the power of competition and the reliability of modern engineering. Routine coolant changes are critical for protecting the compact electric motor's thermal management system, ensuring optimal performance, efficiency, and longevity.

Before you begin: The EE 5 is electrically powered, but it uses a liquid cooling system for the motor and controller components, similar to traditional dirt bikes with combustion engines. Pay attention to Husqvarna's guidelines for coolants that are safe for the specialized aluminum components and plastic used in this model.

What You Need

  • High-quality, approved motorcycle coolant (silicate-free, aluminum-safe)
  • Basic socket set and hand tools
  • Drain pan
  • Funnel
  • Distilled water (if flushing)
  • Protective gloves – coolant can irritate skin

Coolant Change Procedure for the 2022 EE 5

  1. Prepare the bike: Place the EE 5 securely on a level stand. Ensure the bike is completely powered down and disconnected from any charging equipment.
  2. Remove protective plastics: To access the radiator cap and hoses, carefully remove the necessary bodywork panels. This typically requires only a few bolts.
  3. Drain the old coolant:
    • Locate the coolant system's drain bolt, usually positioned at the lowest point of the water pump or radiator system. Place a drain pan underneath.
    • Carefully loosen and remove the drain bolt or the lowest hose clamp. Allow all coolant to completely drain. Remove the radiator cap to speed up draining.
  4. Flush (recommended for older or contaminated coolant):
    • If the coolant was dirty or contaminated, pour a small amount of distilled water into the radiator, reinstall the drain bolt/hose, run the water through (with power off), and drain again.
    • Repeat until the fluid drains clear.
  5. Inspect components:
    • Check hoses, clamps, and the radiator for signs of damage, cracks, or leaks. Replace any worn parts before reassembly.
  6. Refill with fresh coolant:
    • Reinstall and tighten the drain bolt or hose clamp securely.
    • Slowly pour the new coolant into the radiator until it reaches just below the filler neck. The system generally holds a small amount, so add gradually to prevent spill-over.
    • Gently rock the bike side-to-side to help air bubbles escape. Some systems feature a bleeder screw at the highest point – crack this open briefly to release trapped air, then retighten.
  7. Check coolant level and air removal:
    • After filling, reattach the radiator cap. Power up the bike and run it in a safe, ventilated area to circulate coolant throughout the system for a few minutes.
    • Turn off, allow a short cool-down, and recheck the coolant level. Top off as needed.
  8. Reinstall plastics and inspect for leaks: Replace all removed covers and visually confirm there are no drips or seepage.
  9. Dispose of old coolant properly: Never pour used coolant down drains. Take it to a local recycling center or automotive shop that accepts coolant.

Important Notes About the EE 5

  • Only use coolants approved for aluminum cooling systems. Mixing types or using automotive coolant not designed for motorcycles can cause corrosion or damage.
  • The compact nature of the EE 5 means the system holds less coolant than full-size bikes. Take care not to overfill.
  • Coolant protects against both freezing and boiling. For all-season riding or varying temperatures, maintain the correct mixture concentration as recommended by Husqvarna.
  • Regularly check the coolant level – leaks or low coolant can cause the electronic controller to derate power or shut down to prevent damage.
  • Inspect for tight plastic connections; the EE 5 uses multiple quick-connect and molded parts for weight savings and efficient cooling.

By keeping the cooling system in peak condition, you’ll ensure your 2022 Husqvarna EE 5 delivers consistent, reliable rides whether at the track or out on the trails. For OEM and high-performance cooling parts, Shop parts for a 2022 Husqvarna EE 5 Dirt Bike.
