you need to add dextron to your cooling sys. They sell it in a 50/50 bottle already mixed. not adding the correct mixture, can cause problems. If you are asking where the water pump it located, it is the top right pulley. If your looking from the pass. side fender. Is the under side of the hood wet over the belt? if so, then it is most likely your pump. It will leak, on the pulley and slings it around causing the hood to get wet. At least that is what happened to mine when the water pump went out.
