Shop parts for a 2014 Honda CRF125FB Dirt Bike.Routine coolant maintenance is key to keeping your 2014 Honda CRF125FB performing at its best. Over time, old coolant can lose effectiveness, leading to overheating and costly engine problems. Follow this MotoSport-exclusive guide for a safe, thorough, and efficient coolant change specifically for your CRF125FB.
What You'll Need
- Fresh, silicate-free motorcycle coolant (recommended for CRF models)
- Socket set (typically 8mm – 10mm)
- Phillips screwdriver
- Drain pan
- Funnel
- Rags or shop towels
- Protective gloves
Step-by-Step Instructions
- Cool the Engine
Always make sure your bike is completely cool to avoid burns from hot coolant or engine parts. - Access the Radiator Cap
Remove the right side panel by loosening the Phillips screw(s) and any retaining bolts. This will expose the radiator cap. - Open the Radiator Cap
Slowly open the radiator cap to release any built-up pressure. Use a rag to shield your hand in case of sudden steam release. - Locate the Drain Bolt
The CRF125FB places the coolant drain bolt on the lower side of the engine, usually near the water pump. Position a drain pan beneath it. - Drain the Old Coolant
Using the correct socket, carefully remove the drain bolt. Allow all old coolant to completely empty into the drain pan.
Tip for the CRF125FB: The frame and fairings are designed for easy access to the drain bolt – you do not need to strip the whole bike down for this job. - Inspect & Clean
Inspect the old coolant for debris or oil indicating deeper issues.
Wipe away any residue from the drain area. - Reinstall the Drain Bolt
Replace the drain bolt securely, using a new washer if necessary. - Add Fresh Coolant
Using a funnel, slowly pour fresh, pre-mixed coolant into the radiator until full. - Bleed the System
To prevent dangerous air pockets:
– Gently rock the bike side to side.
– Squeeze the coolant hoses by hand.
– Top off coolant if the level drops. - Run & Recheck
Start the engine with the radiator cap off and let it run idle for several minutes. Watch for the coolant to circulate and bubbles to rise (air leaving the system).
Turn off the engine, let it cool, then check and top off the coolant again, if necessary. - Check the Reservoir
Some CRF125FB variants include a small overflow reservoir. Make sure this is filled to the proper level indicated. - Reassemble & Clean Up
Reinstall the side panel and any removed hardware. Wipe up any spilled coolant and responsibly dispose of the old coolant.
CRF125FB Owner Notes
- Factory Interval: Honda recommends coolant changes every 2 years or as specified in your owner's manual, whichever comes first.
- Coolant Choice: Non-silicate formulas are a must for this model to avoid water pump seal wear.
- Easy Access: Unlike many bikes, the CRF125FB offers straightforward access for maintenance—making this task manageable even for DIYers with basic tools.
- Safety First: Never mix different coolant colors or types. Always properly tighten the drain bolt to prevent leaks.
- Aftermarket Skid Plates: If fitted, confirm the drain plug is accessible without full removal. Most common CRF plates allow access.
