Shop parts for a 2022 KTM 350XCF FACTORY EDITION Dirt Bike.

Regular coolant changes are vital to keep your 2022 KTM 350XCF FACTORY EDITION running cool and at peak performance. This unique model features KTM's efficient cooling system, routing coolant from the cylinder head through the frame triangle and into high-performance WP aluminum radiators. Proper care ensures reliable operation – especially during intense rides or hot conditions.

Tools and Supplies Needed

  • Motorcycle-specific coolant (never mix with automotive coolant)
  • Drain pan
  • Socket set and screwdriver
  • Funnel
  • Distilled water (if flushing)
  • Gloves and shop rags

Preparation

  • Make sure the engine is cool to the touch before starting any work.
  • Place your KTM upright on a level surface using a stand.
  • Remove the front and side plastic shrouds if they obstruct access to the radiators or cap.

Draining the Old Coolant

  • Find the radiator cap on top of the right radiator. Carefully remove it to relieve system pressure.
  • Locate the coolant drain bolt, usually found at the lowest point of the water pump cover on the right side of the engine.
  • Place your drain pan under the drain bolt, remove the bolt, and let all coolant flow out. Some coolant may still remain in the lower radiator hoses – gently lean the bike if needed to assist draining.
  • Inspect the old coolant for debris or discoloration, which can indicate underlying problems.

Flushing the System (Optional but Recommended)

  • If you're switching coolant types or haven't changed fluid in a while, flush with distilled water.
  • Reinstall the drain bolt, fill the system with distilled water, run the engine briefly (one to two minutes), then repeat the drain procedure to remove as much old coolant as possible.

Refilling with Fresh Coolant

  • Reinstall the drain bolt and torque to manufacturer specs to prevent leaks.
  • Using a funnel, slowly fill the radiator with your motorcycle-specific coolant until the fluid is visible just below the neck of the radiator cap opening.
  • Some KTM models feature a cylinder bleed screw to ensure all air escapes; open this briefly as you fill, and close it once you see coolant free of air bubbles.
  • If equipped with a remote overflow reservoir, fill it to the indicated level (do not overfill).

Bleeding the Cooling System

  • With the radiator cap off, briefly start the engine and let it idle. As the coolant circulates, trapped air will rise. Top off the coolant if the level drops as bubbles escape.
  • Once bubbling stops and the level stabilizes, reinstall the radiator cap securely.
  • Check for leaks around the drain bolt and hoses.

Aftercare and Inspection

  • Start the engine, allow it to reach operating temperature, then shut off and let cool. Recheck coolant levels and top off if necessary.
  • Inspect radiator fins for mud or debris and clean as needed to maintain optimal cooling, especially after rides in harsh environments.
  • Visually inspect for leaks after your first ride and periodically throughout the season.

Special Considerations for the 2022 KTM 350XCF FACTORY EDITION

  • This model features high-performance WP aluminum radiators and flow-optimized circulation for efficient heat dissipation—critical for racing and aggressive trail use.
  • Improved radiator guards are integrated into the shrouds; ensure guards and fins remain straight and intact to protect from impact and maximize airflow.
  • The frame design makes maintenance easier while providing more working space. Still, always use genuine KTM or approved coolant to prevent internal corrosion.

Follow these steps and your 2022 KTM 350XCF FACTORY EDITION is ready to conquer any trail with optimal engine cooling and reliability.
