How to Change the Coolant in a 2023 Kawasaki KLX110

Shop parts for a 2023 Kawasaki KLX110 Dirt Bike.

The 2023 Kawasaki KLX110 is a popular youth dirt bike, well-known for its durability and simplicity. However, it features an air-cooled engine, which means it does not have a traditional liquid coolant system like many larger or more advanced motocross models. Instead, it relies on air flowing across the engine fins to dissipate heat. For owners, this makes ongoing maintenance much easier–there is no coolant to change or radiator to service. Regular engine oil changes and basic checks are the main ways to keep it running strong.

Important Maintenance Notes for the KLX110

  • No coolant flush is needed: Since the KLX110 does not use liquid coolant, you will not find a radiator, coolant reservoir, or drain bolt dedicated to coolant on this bike. Focus routine maintenance efforts on oil changes, chain care, and air filter service.
  • Oil changes are essential: Keep up with scheduled oil changes–using the correct type and volume of oil specified in your owner's manual. This is the most vital maintenance step to keep your KLX110's air-cooled engine running cool and lasting longer.
  • Clean the engine fins: Inspect and periodically clean the cooling fins on the engine. Dirt and debris can reduce cooling efficiency, so ensure they stay exposed to airflow on rides.
  • Ideal for younger or beginner riders: Air-cooled engines offer fewer parts to maintain or break, making the KLX110 a seamless experience for new riders and parents managing the bike's upkeep.

What If You See Overheating Symptoms?

  • Engine running hot? On rare occasions, such as riding in extreme heat or deep mud, KLX110 engines can get hot. If you notice power loss or oil warning lights, stop the engine–let it cool and inspect oil level as a first step.
  • No need for coolant products: Do not add or use any radiator or coolant additives; these are unnecessary and incompatible with the KLX110 platform.

Summary for KLX110 Owners

  • Your 2023 Kawasaki KLX110 does not require or support coolant changes.
  • Adhere to the service intervals for oil changes, air filter care, and general cleaning to maximize performance and engine longevity.
