We haven't been driving the car much, mostly around the neighborhood while my girlfriend gets used to driving. We took it to get a tag today and it was a 20 min drive in city traffic some stop and go. The needle hit around 210 and when we got there I popped the hood to check it out, the overflow was shaking some and you could hear it bubbling some. Was I supposed to let air out of the system when I filled it? That was my first time doing anything with the cooling system so I'm not sure how to do it. thanks in advance.
