Where does the coolant go in your Nissan Xterra 2002?

while the engine is cold take the radiator cap off located under the hood in front of the motor. top this off with a coolant mixture of 50% coolant and 50% distilled water. do the same for the reservoir to your left. it is a white jug with a screw on cap beside the radiator. it will have a line on the jug about half way down. do not fill above this line.
