Maintaining your 2013 Kawasaki KLX110L is key to maximizing performance on the trails. Regularly changing the coolant ensures optimal engine temperature regulation, protects internal components, and preserves reliability. This step-by-step MotoSport guide is designed specifically for the KLX110L, covering everything you need for a successful coolant change on your dirt bike.
What Makes the KLX110L Unique?
The 2013 Kawasaki KLX110L is well-known for its approachable size, extra ground clearance, and enhanced suspension compared to standard KLX models. It does not have a large, external radiator – instead, its compact air-cooled engine does use supplemental coolant in some climates or modified setups. Always consult your owner's manual to verify your model's cooling system specifics. If your bike includes a coolant reservoir or has been upgraded to a big-bore head with a secondary radiator, follow the procedure below. For most stock KLX110Ls, this coolant change routine applies if you see a cap and fluid reservoir on the cylinder head area.
Coolant Change Instructions
- Preparation
- Ensure the engine is completely cool to avoid burns.
- Gather supplies: new coolant (use motorcycle-specific coolant or premixed 50/50 ethylene glycol & distilled water), 8mm and 10mm sockets, Phillips screwdriver, a drain pan, funnel, and clean rags.
- Work in a well-ventilated area free of children and pets – used coolant is toxic.
- Access the Cooling System
- If equipped, remove the seat and right-side plastic covers using an 8mm socket to expose the coolant reservoir and fill cap area.
- Drain Old Coolant
- Place a pan under the water pump or drain bolt location on the crankcase or lower hose (check for a small bolt labeled drain).
- Loosen and remove the radiator or system fill cap to allow air flow.
- Remove the drain bolt completely and let coolant flow out completely.
- If there's a reservoir tank, disconnect the hose & drain it out as well.
- Flush (Optional but Recommended)
- Reinstall the drain bolt loosely and fill the system with distilled water.
- Run the engine for 1–2 minutes to circulate, then repeat the drain step to remove contaminants. Do not use tap water, as it can cause mineral buildup.
- Refill with Fresh Coolant
- With the drain bolt reinstalled and tightened securely, use a funnel to slowly fill the system with new coolant. Fill up to the neck or the designated level on the reservoir if equipped.
- Gently rock the bike and squeeze hoses to help expel trapped air.
- Bleed & Check for Air
- Start the engine with the cap off and let it idle for several minutes. Watch as air bubbles escape – add more coolant if the level drops.
- Reinstall the fill cap once bubbling stops and the coolant is at the correct level. Avoid spills on painted parts.
- Inspect Levels After Heating
- Allow the bike to fully warm up, then let it cool back down. Recheck coolant levels and top off if necessary.
- Replace any side panels or the seat.
- Dispose of Old Coolant Properly
- Collect all drained fluids in a sealed container and deliver to your nearest recycling or hazardous waste center.
Tips for KLX110L Owners
- Always use the type of coolant recommended for aluminum engines to prevent corrosion.
- KLX110L's compact cooling system means careful attention to air pockets when refilling; never overfill.
- If your KLX110L is heavily upgraded (race head, high-compression piston), cooling system demands increase – monitor temperature after riding.
Servicing your cooling system extends your KLX110L's lifespan and keeps its engine running at peak performance. Prioritize routine checks, and enjoy the ride with confidence.
