Also, you didn't answer the question asked: how old (and also) what is the mileage on this car?

Sorry, 2004 and about 132.000 Also i think there might be a small leak in the radiator but not sure. if there is a small leak what about using a stop leak it should work and will be a lot cheaper than buying a new radiator
