You repeatedly use the word "water" in your post. If you are using straight water you will fail. Be sure to use 50/50 coolant and water. If you have flushed the system with water, add 2 gallons of straight coolant first and then clean water until full. The system holds over 4 gallons total. Water boils at about 210 degrees F, 50/50 mix boils at about 270 degrees F. Remove the upper grill to get to the bolt used for bleeding the radiator. It is at the top of the radiator on the side that the hoses come to. Mark
