If you ride a 2014 KTM 350XCFW, keeping your cooling system in top shape is crucial for reliable performance and engine life. The 350XCFW uses a liquid-cooled, high-revving engine that's especially sensitive to coolant quality and proper system maintenance. Here's a MotoSport-exclusive guide for a professional coolant change tailored for this model – with KTM-specific notes included.

What You Need

  • Fresh high-performance motorcycle coolant (check owner's manual for spec)
  • Drain pan
  • 8mm socket or wrench
  • Funnel
  • Shop rags
  • Distilled water (optional for flushing)
  • Protective gloves

Preparation

  • Let the engine cool completely before you begin. Hot coolant is dangerous and can cause burns.
  • Stand your KTM 350XCFW upright on level ground using a stand.
  • Remove any plastic covers or shrouds if they block access to the radiator cap or water pump.

Draining the Coolant

  • Remove the radiator cap to release any pressure in the system.
  • Locate the coolant drain bolt on the water pump cover (right side, lower part of engine case). Place your drain pan beneath it.
  • Use your 8mm socket to remove the drain bolt. Allow coolant to fully drain into the pan.
  • Inspect the coolant. Milky color may indicate oil contamination; deep rust means overdue maintenance.
  • If you wish to flush the system (especially when switching coolant types), reinstall the drain bolt, fill the system with distilled water, start the bike and let it run for a few minutes, then repeat the drain process. This helps remove old coolant and contaminants.

Refilling the Coolant

  • Reinstall the drain bolt. Tighten to factory spec but do not overtighten.
  • Slowly pour fresh coolant into the radiator with a funnel until the level reaches just below the neck.
  • KTM recommends occasionally tilting the bike side-to-side to help air escape. Gently squeeze the upper radiator hose to expel trapped air bubbles.
  • On the 350XCFW, check for a cylinder head bleed screw – this model may allow you to bleed remaining air for a perfect fill. Crack the bleed screw until coolant drips out, then retighten.
  • Reinstall the radiator cap securely.

Check and Final Steps

  • Start the bike and let it idle briefly, observing the coolant level and checking for leaks.
  • Turn off the engine and let it cool. Remove the radiator cap and top off coolant if needed.
  • Inspect hose clamps and the radiator cap for good fit; replace if damaged.
  • Double-check that all bolts and fasteners are snug.

2014 KTM 350XCFW Owner Notes

  • This model has a compact, high-power engine that relies on efficient cooling, making timely coolant changes (at least every two years, or more often if you ride hard) essential.
  • The KTM 350XCFW's radiator design allows for fast draining, but air pockets can be stubborn without tilting and bleeding – pay special attention to removing air for optimal performance.
  • Recommended coolant capacity is approximately 1.2 liters, but always confirm by filling to just below the cap's neck as overfilling can cause excess pressure and loss under extreme riding.
  • Use only high-quality, motorcycle-specific coolant to prevent corrosion & overheating issues common to aluminum KTM radiators.

Routine coolant changes on your 2014 KTM 350XCFW will help you avoid overheating, preserve engine life, and ensure you're ready for every ride. For parts, radiators, and coolant options designed specifically for your model, MotoSport has your back.
