Regularly changing the coolant in your 2020 Suzuki RMZ250 is essential for peak engine performance and longevity. Neglecting this maintenance task can lead to overheating, internal corrosion, and eventual engine damage—especially important given the high-performance demands of this motocrosser. Here’s a robust, model-specific guide to help MotoSport riders perform the job safely and efficiently.
What Owners Should Know About the 2020 RMZ250
- Aluminum Radiator Construction: Always use a premium coolant compatible with aluminum components. Avoid silicate-based coolants, which can corrode the alloy passages.
- Specified Capacity: The cooling system of the 2020 RMZ250 takes about 950 ml (1.0 US quart) of coolant when serviced properly.
- Regular Inspection: Periodic checks are critical since even small leaks or blockages in the RMZ250’s compact system can have immediate performance impacts.
Step-By-Step Coolant Change Guide
-
Prepare the Bike & Workspace
Ensure the RMZ250 is on a stable stand and the engine is completely cool before starting. Prepare a drain pan, a new gasket washer, the correct coolant, a 10mm socket, and basic hand tools. -
Remove the Radiator Cap
Slowly open the radiator cap to release any built-up pressure. Never open a hot radiator–the RMZ250’s compact system builds pressure rapidly, risking serious burns. -
Drain Old Coolant
Locate the coolant drain bolt (lower right side of the water pump). Place your drain pan underneath, then remove the bolt and allow all coolant to empty. -
Replace the Gasket Washer
Always install a new gasket washer on the drain bolt to prevent leaks. Tighten the bolt to the manufacturer’s spec: 11 Nm (8.0 lbf-ft). -
Bleed Air From the System
Loosen the air bleeder bolt on the cylinder head slightly. -
Add New Engine Coolant
Fill the radiator with the recommended coolant (50:50 mix with distilled water, unless using pre-mixed) up to the bottom of the filler neck. -
Remove Air Pockets
With the bleeder bolt loose, slowly add coolant until it emerges from the bleeder, then tighten the bolt. This ensures trapped air is purged for system efficiency. -
Check for Leaks & Reinstall the Cap
Wipe down the area, check all connections, and properly reinstall the radiator cap. -
Final Inspection
Start the bike, let it idle, and check for leaks. When fully cool, recheck the coolant level and top off if needed.
Pro Tips for the 2020 Suzuki RMZ250
