Regular coolant changes are essential for peak performance & lifespan of your Kawasaki KLX110. The 2026 model, known for its durability & easy maintenance, features a simple cooling system with user-friendly access. This MotoSport-exclusive guide will show you how to change the coolant safely & efficiently, with tips specific to your KLX110.
What Makes the 2026 KLX110 Unique?
The KLX110 is an air-cooled play bike with a legendary reputation for reliability. Unlike liquid-cooled models, many small-bore Kawasaki KLX110s use air as the primary cooling source. However, should the 2026 model offer an upgraded or region-specific liquid-cooling variant, the process below covers all necessary steps to flush & refill your cooling system. Always consult your owner's manual to confirm if your model has a radiator and coolant system or not – and follow MotoSport for model-specific updates.
What You Need
- Fresh, compatible coolant (avoid using plain water)
- Drain pan
- Socket set (common sizes: 8mm – 12mm)
- Funnel
- Protective gloves & rags (coolant is toxic and tough on paint)
- Distilled water (for flushing, if desired)
Step-by-Step: Changing Coolant on Your KLX110
-
Preparation
Make sure the engine is completely cool before starting. Place your dirt bike on a level surface, ideally on a stand. -
Access the Radiator
If equipped, remove any side panels or guards obstructing the radiator or reservoir cap. -
Drain the Old Coolant
Locate the drain bolt at the bottom of the radiator or water pump. Place the drain pan under the bolt, then remove the radiator cap slowly to release pressure. Use the socket set to remove the drain bolt and let all old coolant flow out.
Pro tip: While it drains, gently rock the bike side to side to ensure a complete empty. Dispose of old coolant responsibly as it is hazardous. -
Flush the System (Recommended)
Reinstall the drain bolt. Fill the system with distilled water, replace the radiator cap, start the bike and let it idle for a few minutes. Shut off, remove the cap, and drain again. Repeat if fluid is dirty. -
Add New Coolant
With the drain bolt secured, use a funnel to slowly pour in fresh coolant until it's just below the filler neck or up to the marked full level.
If your model has a separate reservoir, fill it to the "full" mark. -
Remove Air Pockets
With the cap still off, start the engine & let it idle for a few moments to work out trapped air. Watch for bubbles escaping from the filler neck. Shut off, top off as needed, and reinstall the radiator cap securely. -
Final Checks
Run the bike up to normal temperature, then let it cool completely. Double-check radiator and reservoir levels, topping off if needed. Inspect for leaks around drain bolt and hoses.
Model Owner Tips
- Check the coolant at regular service intervals, especially if ridden hard or in hot conditions.
- The KLX110's compact design makes most maintenance tasks straightforward – but always allow the engine to cool fully before opening the system.
- Never mix different coolant types (silicate vs. non-silicate), and avoid tap water due to mineral buildup risks.
Following these steps ensures your 2026 Kawasaki KLX110 stays cool, runs right, and continues to deliver trailside fun for years. For all parts, upgrades & more expert maintenance advice, make MotoSport.com your first stop.
