Changing the coolant in your 2022 Honda CRF110F is a straightforward process, but it's vital to follow each step with care to ensure proper engine cooling and long-term reliability. Below, MotoSport provides an exclusive, model-specific guide that covers every step – with a few important notes unique to your CRF110F.

What You Need

  • Fresh silicate-free engine coolant formulated for aluminum engines
  • Socket set and ratchet
  • Flathead screwdriver
  • Funnel
  • Drain pan
  • Rags or towels for cleanup
  • Protective gloves

Coolant Change Interval

For the 2022 CRF110F, Honda recommends changing the coolant every two years or as needed based on riding conditions. If you frequently ride in muddy, sandy, or excessively dusty environments, consider inspecting and changing coolant more often.

Step-by-Step Coolant Change Instructions

  1. Let the Engine Cool. Always allow the engine to cool completely before opening the radiator cap to avoid the risk of burns from hot pressurized coolant.
  2. Remove the Left Side Panel. Using your socket set, unfasten the bolts securing the left side radiator shroud and set the panel aside for access to the radiator.
  3. Remove the Radiator Cap. Slowly and carefully remove the cap with a screwdriver. Keep a rag handy for any minor drips.
  4. Position the Drain Pan. Place your drain pan directly beneath the radiator drain bolt – typically located at the lowest part of the radiator housing or water pump cover. The CRF110F has a compact cooling system, so take care not to lose the drain bolt or washer when loosening it.
  5. Drain the Old Coolant. Loosen and remove the drain bolt. Let all the coolant fully drain into your pan. Dispose of used coolant safely according to your local regulations, as it is toxic and harmful to the environment.
  6. Inspect and Replace the Washer. Inspect the drain bolt washer for any signs of wear or damage. Always use a fresh washer to prevent leaks when reinstalling the bolt.
  7. Reinstall the Drain Bolt. Tighten the bolt securely per Honda torque specs (typically in the range of 7-9 lb-ft for CRF110F–always double-check your owner's manual for specification).
  8. Refill the Cooling System. Using a funnel, pour fresh silicate-free coolant slowly into the radiator until it reaches the top of the filler neck.
  9. Bleed the Cooling System. Tap radiator hoses and gently rock the bike side to side to help release any trapped air. Reinstall the radiator cap securely.
  10. Start the Engine and Recheck. Fire up the engine and let it idle for several minutes until it reaches operating temperature. Let it cool again, remove the radiator cap, and top off coolant if necessary.
  11. Reinstall the Panels. Once levels are correct, reinstall the radiator shroud and any panels you removed.

CRF110F Model-Specific Notes

  • The 2022 CRF110F uses a simple, reliable air/liquid cooling system that requires proper coolant level for safe operation – running low can cause overheating and engine damage.
  • Unlike race-focused CRF models, the CRF110F has a modest capacity, making it quick and economical to service.
  • This engine is tuned for beginner-friendly power delivery, but maximum engine protection depends on a properly serviced cooling system. Coolant neglect is a common source of premature engine wear and performance issues.
  • Always double-check for leaks after the first heat cycle of operation and keep a close eye on coolant level for your next few rides.

Pro Tips for Your Honda CRF110F

  • Never mix coolant types. Always use manufacturer-approved formulas designed for motorcycle use and avoid automotive coolants with silicates or phosphates.
  • Store leftover coolant in a sealed container, away from pets and children.
  • If you ride in extremely cold or hot climates, verify that your coolant offers appropriate freeze and boil-over protection.
