2) Remove the radiator drain bolt and radiator cap. Refer to your owner’s manual for the exact location, but they are generally at the bottom of the radiator. Put a pan under the drain bolt to catch the draining fluid.
5) Premix your ATV coolant with distilled water. A 50/50 mixture is the most common. You can also add anti-freeze and Water Wetter if needed. Refer to your owner’s manual for the correct ratios to use depending on the temperature where your ATV is operated. Each type of ATV will have different recommendations.
6) Put a funnel in the coolant tank and pour your coolant mixture into the funnel. You will see lines on the side of the tank telling you the correct level to pour. Replace both caps and the rubber gasket when you are finished filling the tank.
