Keeping your 2013 KTM 250XCFW running cool is essential for maximum performance – especially on tough trails or long rides. Regularly changing the coolant is a crucial maintenance task to ensure efficient engine cooling and to prevent costly damage from overheating or corrosion. This proprietary MotoSport guide will walk you through every step, including specific model tips to make your coolant change easy and effective.
What Makes the 2013 KTM 250XCFW Unique?
This model features a high-compression 4-stroke engine with a compact twin-radiator setup, exposed rads, and typical KTM service-friendly design. The cooling system is robust for off-road use but can be sensitive to air pockets if not bled properly. Always use a high-quality, premixed, silicate-free coolant approved for aluminum engines.
Tools & Supplies Needed
- Premixed motorcycle coolant (aluminum-safe, silicate-free)
- 8mm socket or wrench
- Catching container (for old coolant)
- Funnel (optional, helps reduce spills)
- Shop towels
- Torque wrench (recommended for reinstalling drain bolt)
- Protective gloves & safety glasses
Step-by-Step Coolant Change Process
- Let the engine cool completely. Never remove the radiator cap on a hot bike—the system can be under pressure, and hot coolant can cause severe burns.
- Remove the seat and left radiator shroud for easier access to the radiator cap and water pump if needed.
- Position the bike upright (use a stand or have a helper hold it level).
- Remove the radiator cap. (Left radiator, twist counterclockwise.)
- Place a container under the water pump drain bolt. The drain bolt is located on the lowest point of the water pump cover (lower right side of the engine).
- Remove the 8mm drain bolt and allow the coolant to fully drain. For faster flow, ease any hoses by gently squeezing but do not force sealed connections.
- Inspect the old coolant for oil or debris. Milky or contaminated fluid may indicate gasket wear and requires further inspection before refilling.
- Reinstall the drain bolt with a new crush washer if needed. Torque to the factory spec of 10 Nm (7.4 lbf ft), avoiding over-tightening.
- Pour in fresh coolant slowly through the radiator filler, filling to just below the bottom of the filler neck.
- "Burp" the system: Gently tip the bike side to side to help any trapped air escape, then fill again as the level drops.
- Reinstall the radiator cap.
- Start the bike and let it run for a few minutes until warm. Watch the coolant level at the radiator and overflow as the engine heats. Let the engine cool fully, then recheck both levels and top off as necessary. It is normal for the level to drop slightly after the first heat cycle as remaining air escapes the system.
- Reinstall bodywork and check for leaks.
Maintenance Tips & Cautions for KTM 250XCFW Owners
- Only use motorcycle-specific coolant. Automobile coolant may contain silicates or chemicals incompatible with the KTM's alloy components.
- Flush the system if swapping coolant types.
- Check your cooling fan (if equipped), hoses, and radiator for leaks or blockages every time you change coolant.
- Avoid running low on coolant or allowing air pockets in the system. The 250XCFW's head gasket and water pump seals are sensitive to overheating and low coolant levels.
- Disposal: Collect old coolant in a sealed container and take it to your local hazardous waste disposal site—do not dump it.
Changing the coolant on your 2013 KTM 250XCFW not only prolongs engine life—it boosts reliability and performance so you can ride with confidence. For all your OEM and aftermarket parts or upgrades, trust MotoSport for your 250XCFW needs.
