Preparation: Tools & Supplies
- Genuine Honda or compatible silicate-free motorcycle coolant

- Clean rags

CRF50F Coolant System Notes
- The 2018 CRF50F uses an air-cooled engine and does not have a liquid-cooled radiator system, unlike larger CRF models.
- What is typically called a 'coolant change' on liquid-cooled bikes is instead an engine oil change and external cooling fin cleaning for this model.
- For liquid-cooled Honda CRFs, follow steps below, but for the CRF50F, routine checks involve oil and airflow, not coolant.
Step-by-Step Instructions for Liquid-Cooled CRFs
*If you own a CRF model with liquid cooling (not the CRF50F, but for reference in case you maintain multiple bikes)*:
- Let the bike cool completely. Never open the radiator cap when hot.
- Remove the radiator/tool side shrouds or covers as needed for access.
- Position a drain pan under the water pump. Locate and remove the coolant drain bolt on the water pump cover. Remove the radiator cap to allow full drainage.
- Once drained, inspect and replace the drain bolt washer if needed. Reinstall and torque the drain bolt to manufacturer spec.
- Fill the radiator with premixed coolant or dilute concentrate with distilled water as specified. Pour slowly using a funnel to avoid air bubbles.
- Reinstall radiator cap securely. Run the engine at idle to circulate the coolant; check for leaks and top off as necessary.
2018 CRF50F Model Owner Tips
- The CRF50F does not require coolant changes since it relies on air cooling. Prioritize keeping engine fins clean and clear of debris for optimal performance.
- Change engine oil regularly and replace the oil filter if equipped.
- Inspect for oil leaks or excessive grime buildup which can act as insulation and raise engine temperature.
- If you are new to dirt bike maintenance, always reference your CRF50F owner's manual for oil change intervals and air filter service schedules.
- Check for any model-specific service bulletins on the MotoSport website before starting your next ride.
Keep your CRF50F running cool and reliable by focusing on clean airflow across the cooling fins, regular oil changes, and attentive engine hygiene. For genuine CRF50F-specific parts and maintenance items, remember – MotoSport.com has you covered.
