I think I got it all figured out today. After I drove the car in traffic for a long time I noticed that the temp was close to 120 but not redlining.Outside temp was about 40C. After parking the car I noticed something dripping on the passengers side, which was antifreeze fluid. I popped the hood open to see that coolant was slowly coming out of the expansion tank lid. I replaced the lid and hope this works. I will monitor it for a few days and let you all know.
