How to Change the Coolant in Your 2024 GASGAS MC 250F
Keeping the cooling system in top shape is essential for the performance and longevity of your 2024 GAS GAS MC 250F. This step-by-step MotoSport-exclusive guide details how to change the coolant, with MC 250F-specific tips every owner should know.
Why Coolant Change Matters
Coolant not only regulates engine temperature but also protects internal components from corrosion and deposits. GAS GAS recommends changing coolant as part of your regular maintenance or if you notice any signs of contamination or low coolant levels.
Before You Begin
- Make sure the bike is completely cool to avoid burns.
- Place the bike on a stable stand and use tension belts to prevent it tipping over during maintenance.
- Use only high-quality, motorcycle-specific coolant that is silicate, phosphate, borate, & nitrate-free for best compatibility with your MC 250F's water pump and seals.
- Wear safety gloves and eye protection, and have rags ready for spills.
Tools & Supplies Needed
- Socket set (commonly 8mm for the drain boltdouble-check prior to removal)
- Drain pan
- Fresh coolant
- Funnel
- Clean water (distilled) for flushing, if needed
Step-by-Step: Coolant Change Procedure
1. Access the Radiator
- Remove the shrouds or panels covering the radiator cap, if equipped.
- Unscrew the radiator cap slowly to release any pressure.
2. Drain the Coolant
- Locate the coolant drain bolt on the water pump coverusually the lowest bolt. Place the drain pan underneath.
- Remove the drain bolt (and any copper washer) and allow the system to fully drain.
- To improve drainage, gently tilt the bike or remove the lower radiator hose.
- Inspect the old coolant for debris or discoloration, which may indicate internal corrosion. If you see these, consider flushing the system.
3. Flush the System (Optional but Recommended)
- Reinstall the drain bolt temporarily and fill the radiator with distilled water.
- Reinstall the cap, start the engine, and run briefly (do not overheat the bike).
- Repeat the drain process until only clear water exits the system.
4. Reinstall Drain Bolt
- Make sure the copper washer is in good conditionreplace if necessary.
- Torque the drain bolt to the manufacturer’s recommended spec (typically around 10 Nm, but confirm for the MC 250F).
5. Add Fresh Coolant
- Using a funnel, pour new coolant slowly into the radiator until it reaches the bottom of the filler neck.
- On the MC 250F, inspect radiator hoses and connections for leaks or wear during this step. The radiator is pressurizedany loose clamps can result in coolant loss during riding.
6. Bleed the System
- Lean the bike gently side to side to help release trapped air bubbles.
- With the radiator cap removed, start the engine and let it idle for a few minutes. Add coolant as needed until bubbles disappear and the level stabilizes.
7. Replace Radiator Cap and Check for Leaks
- Secure the radiator cap and reassemble any plastic shrouds removed earlier.
- Start the bike and let it reach operating temperature. Check for leaks at all hose connections and around the drain bolt.
MC 250F Model Notes
- The 2024 MC 250F is engineered with tight clearances and high operating pressures. Always use the correct radiator cap and do not substitute automotive coolants with silicates—they can damage the lightweight alloy water pump and seals.
- Inspect radiator guards, fins, and hoses after tip-overs, as the compact cooling system is sensitive to airflow restrictions and leaks.
- Overheating can result if radiator fins become clogged with mud or sand; clean carefully with compressed air or soft brush post-ride.
Disposal & Environmental Precautions
- Do not dispose of old coolant down household drains or in the environment—catalytic agents are toxic to wildlife.
- Always recycle used coolant at a certified collection point.
Regular coolant changes on your MC 250F not only preserve engine health but also ensure maximum performance whether you're at the track or trail. Routine checks can help catch leaks early and prevent costly engine repairs down the line.
