I just got the coolant flushed and oil change in my 2015 altima. I was driving it home from the mechanic and noticed it was driving really hot (on the overheat line). blasted hot air and it kept going down to halfway (usually where it stays) and then coming back up. Internet says its an air pocket. I have an appointment at a nissan dealership to get my transmission fluid changed. Is it ok to wait until then to fix the coolant problem? I have to drive to work today and tomorrow before the appointment?
