Changing your coolant regularly is one of the simplest ways to protect the engine and cooling system on your 2014 Honda CRF250R. Honda recommends doing this service regularly to maintain optimal performance and prevent overheating or corrosion-related damage. Below you will find a proprietary MotoSport step-by-step guide specific to your CRF250R, including model-specific tips that every owner should know.
What You Will Need
- Fresh, silicate-free motorcycle coolant (glycol-based)
- Drain pan
- 8mm socket or wrench (for water pump drain bolt)
- Phillips screwdriver (for radiator cap cover, if equipped)
- New copper or aluminum crush washer for drain bolt
- Funnel (helpful for filling without spills)
- Clean rags or paper towels
- Distilled water (if diluting concentrate)
- Torque wrench (recommended for proper reinstallation)
Before You Begin
- Allow your CRF250R to cool completely. Never open a hot radiator as pressurized coolant can cause severe burns.
- Ensure the bike is upright and securely supported for safety.
Step-by-Step Coolant Change Procedure
- Remove the Radiator Cap:
- Locate the radiator cap on the left radiator. If your bike has a plastic radiator shroud or cap cover, remove it using a Phillips screwdriver.
- Slowly loosen and remove the radiator cap to relieve any residual pressure.
- Drain the Old Coolant:
- Place your drain pan below the water pump (right side of the engine).
- Locate and remove the coolant drain bolt on the water pump with an 8mm socket. There is typically a crush washer under this bolt; be prepared to replace it.
- Allow coolant to fully drain from the system. Tilting the bike gently from side-to-side can help release trapped fluid.
- Flush (Optional but Recommended):
- If the coolant is very dirty or you are switching coolant types, flush the system with distilled water. Reinstall the drain bolt (temporarily), fill with distilled water, run the engine briefly, then let it cool and drain again.
- Install the Drain Bolt:
- Replace the copper or aluminum crush washer with a new one to ensure a proper seal.
- Tighten the drain bolt to Honda's specified torque value of 10 Nm (7 lb-ft) to avoid leaks–this is important for the CRF250R's alloy cases.
- Fill with Fresh Coolant:
- Begin pouring new, silicate-free coolant into the radiator using a funnel. The capacity for a coolant change is 0.98 US qt (0.93 L). Only fill to the base of the filler neck–do not overfill.
- Reinstall the radiator cap securely; improper installation can cause leaks or overheating.
- Start the Engine & Bleed Air:
- Start the bike and let it run at idle with the radiator cap on for 2-3 minutes. This circulates coolant and purges air bubbles.
- Shut off the engine and allow the bike to cool. Recheck the coolant level–top off if low to the bottom of the filler neck.
- Inspect for Leaks:
- Check around the drain bolt and radiator for signs of leaks. Retighten as needed but do not overtighten the drain bolt.
- Reinstall Any Plastics or Shields:
- Replace any side panels, shrouds or skid plates you removed during the process.
Model-Specific Notes for the 2014 CRF250R
- Cooling System Capacity: The 2014 CRF250R holds just under 1 US quart at a coolant change, so do not overfill–check level after your first ride and top off if necessary.
- Radiator Cap: Always ensure the cap is fully and properly installed. A loose cap can result in significant coolant loss leading to overheating.
- Regular Checks: It is normal to lose 0.7–2.0 oz of coolant through the overflow, especially after aggressive riding. If you notice more loss, inspect hoses and connections to avoid overheating.
- Competition Use: This model is race-oriented with higher engine temperatures. Consider changing coolant more often if riding extreme conditions or using the bike for racing.
Regular coolant service is a key aspect of maintaining your Honda CRF250R's performance and reliability. Keep your cooling system in check, and enjoy worry-free rides on the track or trail.
