How to Change the Coolant in a 2013 Honda CRF110F: A MotoSport Proprietary Guide

Changing the coolant in your 2013 Honda CRF110F is an essential maintenance task that ensures your dirt bike runs cool and delivers top performance on the trail or track. While the CRF110F is known for its reliability and low maintenance demands, sticking to a regular maintenance schedule will help you avoid overheating and extend engine longevity. Here’s a unique, step-by-step MotoSport.com guide tailored specifically for your CRF110F:

Why Coolant Change Matters for the 2013 CRF110F

Though small in displacement, the CRF110F’s air-cooled single-cylinder engine operates at high temperatures, especially in off-road conditions and during summer riding. While some models use purely air cooling, the presence of a coolant reservoir on newer units ensures more even temperature control. Always confirm your bike’s cooling system before starting this service. Using high-quality, silicate-free coolant with corrosion inhibitors is essential – the wrong coolant can damage seals or internals.

Tools & Supplies Needed

• Silicate-free motorcycle coolant (premixed or concentrate per manufacturer–s recommendation)
• Clean funnel
• Shop towels or rags
• Socket set (typically 8mm and 10mm)
• Phillips screwdriver
• Pliers (for hose clamps, if equipped)
• Drain pan suitable for fluids
• Replacement sealing washer, if equipped on drain bolt
• Safety gloves and eye protection

Step-by-Step: Draining & Refilling Coolant

1. Prepare the Bike
   Ensure the engine is completely cool to avoid burns. Support the bike on a level surface using a stand or kickstand.
2. Remove Body Panels
   Remove the right-side panel to expose the coolant reservoir and radiator cap (if equipped). Usually, you need a Phillips screwdriver and a socket wrench for these screws and bolts.
3. Access the Radiator Cap
   If your CRF110F is equipped with a radiator cap, remove the set screw and carefully loosen the cap to relieve any pressure.
4. Locate the Drain Bolt/Plug
   If there is a drain bolt (consult your service manual or inspect the bottom of the engine), place a pan underneath. Loosen and remove the drain bolt. If a sealing washer is present, remove it and plan to install a new one during reassembly.
5. Drain Old Coolant
   Allow all old coolant to fully drain into the pan. Gently rock the bike if needed to remove trapped fluid.
6. Inspect and Reinstall
   Inspect the drained coolant for any signs of oil or debris. Reinstall the drain bolt with a new sealing washer, tightening to the recommended torque (consult your owner’s manual).
7. Fill with New Coolant
   Place a funnel into the radiator or coolant reservoir. Carefully pour in fresh coolant, stopping when it reaches the max fill line or just below the neck of the radiator.
8. Bleed Air from the System
   If your model has a bleeding procedure, briefly run the engine with the cap off (never rev or blip throttle). Top off as air escapes. If there is no specific bleed screw, gently rock the bike side-to-side to help trapped air escape.
9. Reinstall the Cap and Panels
   Replace and secure the radiator/reservoir cap and reinstall bodywork.
10. Final Checks
    Start the engine and let it idle, monitoring the coolant level and checking for leaks. Shut off the engine, let it cool, and verify the coolant is still at the correct level.

Special Considerations for Your CRF110F

• The 2013 CRF110F is designed with simplicity – not all units have a full liquid coolant system. Most are air-cooled or semi-pressurized, so confirm your setup. If unsure, reference your owner’s manual or inspect for a coolant reservoir and radiator hoses.
• A properly sealed system keeps the engine running cooler and protects against premature wear. Any lost coolant or leaks can quickly lead to overheating on this high-revving, durable four-stroke engine.
• It's recommended to use factory-spec replacement coolant for optimal protection and longevity, especially if your bike is under warranty or ridden in extreme climates.

Disposal of Old Coolant

Do not pour used coolant down household drains or into the ground. Take it to a local recycling center or hazardous waste facility.

Regular Maintenance Tip

Change coolant at least every two years or after prolonged periods of hard use. Regular inspection of hoses and seals on your CRF110F will help catch minor problems before they develop into bigger (and costlier) ones.
