3. INSPECTION/ADJUSTMENT ATV 300/250 Maximum Mark Minimum Mark COOLING SYSTEM COOLANT LEVEL INSPECTION Place the machine on the level ground. Check the coolant level in the coolant reservoir when the engine is cold as the coolant level will vary with engine temperature. The coolant level should be between the maximum and minimum marks. If the level is low, remove the coolant reservoir cap, and then add coolant or distilled water to raise it to the specified level. Coolant Reservoir Cap Recommended Coolant: SIGMA Coolant (Standard Concentration 30%) The coolant level does not change no matter the engine is warm or cold. Fill to the maximum mark. COOLANT REPLACEMENT Perform this operation when the engine Radiator Cap is cold. Remove the front fender. (page 2-5) Remove the radiator cap. Remove the drain bolt to drain the coolant. Drain the coolant in the reserve tank. Reinstall the drain bolt. The coolant freezing point should be 5 °C lower than the temprature of the riding area. Coolant capacity: 1.4 L (1.23 lmp qt, 1.48 US qt) Radiator capacity: 1.1 L (0.97 lmp qt, 1.17 US qt) Reserve tank capacity: 0.3 L (0.26 lmp qt, 0.32 US qt) Start the engine and check if there are no bubbles in the coolant and the coolant level is stable. Reinstall the radiator cap. If there are bubbles in the coolant, bleed air from the system. Fill the reserve tank with the recommended coolant up to the maximum mark. Drain Bolt 3-20
