What type of antifreeze goes in Yamaha 400?

For a Yamaha 400, it’s recommended to use an ethylene glycol-based antifreeze that is specifically formulated for use in motorcycles and all-terrain vehicles (ATVs). Look for a coolant that is silicate-free and has corrosion inhibitors to protect the engine and cooling system. Always check the owner's manual for specific recommendations regarding the coolant type and mixture ratio.
