you have a 97 so your lower coolant elbow is case on the alt bracket, follow the directions in the how to to the T or the timing cover can break. chances are the lower O ring blow out on the cast elbow. you take the new O ring off the new pair of dorman elbows.
if your leaking coolant it will of course have air, but if its pushing it out only to the over flow tank the rad cap could be worn out, or a head gasket is blown.
if your over heating real fast when its full of coolant id lean towards a head gasket for sure.
