I have a 2002 Subaru Impreza WRX wagon. Yesterday, while sitting in traffic, I noticed that my temperature gauge was all the way in the red. I glance at it occasionally (weekly), and this is the first time I’ve noticed a high temperature. I continued on to my destination, parked the car for about two hours, and then drove the car home. For the first three to five minutes, it was fine (below the middle mark), but then it slowly crept up, steadily but surely, to the RED HOT zone. It crept up there over the course of about 15-20 seconds. Any idea what would suddenly cause this? Thanks! — Travis
