If you own a 2020 Kawasaki KLX110, keeping up with regular maintenance is essential to ensure long-term performance and reliability. This guide covers everything you need to know for changing the coolant on your KLX110, plus a few crucial tips unique to this model.

Important Note About the KLX110

The 2020 Kawasaki KLX110 is air-cooled and does not use liquid engine coolant or a traditional radiator system. This means there is no liquid coolant to change on this particular dirt bike model. Instead, your KLX110 relies on air passing over the cooling fins on the engine to maintain safe operating temperatures.

What Maintenance Should You Do Instead?

  • Oil Changes: Regularly change your engine oil according to the maintenance schedule to ensure optimal engine health.
  • Air Filter Cleaning: Clean and oil your air filter periodically, especially if riding in dusty conditions.
  • Check Cooling Fins: Keep the engine's cooling fins clear of mud, dirt, and debris to maximize airflow and cooling efficiency.

Air-Cooled System – Owner Reminders

  • Never attempt to add or top off coolant—the KLX110 design does not include a radiator or reservoir.
  • Perform regular inspections to ensure the engine is not overheating, especially after long or hard rides.
  • If you notice overheating, verify that nothing is obstructing the engine fins, and confirm oil level is adequate.

KLX110 Maintenance Quick Tips

  • Replace engine oil every 10 hours of riding or after every significant ride.
  • Inspect and clean cooling fins with a soft brush to prevent dirt buildup.
  • Tighten all fasteners and check for oil leaks routinely.

Your 2020 KLX110 is engineered for simplicity and reliability. While it doesn't require coolant changes, diligent basic maintenance keeps your adventure-ready dirt bike running cool and strong for seasons to come.
