We just bought a 2003 Subaru Outback. It’s got a transmission issue that we’re having looked at tomorrow. It’s our only transportation at the moment so we’re being very gentle with it. We drove to our sons house today, 45 min from our house, with a stop at the Kroger nearest his house on the way. After we left his house, we were planning on stopping at Costco which was on the way home. It’s an 18 minute drive from his house to Costco. About 3 min from Costco the AC quit blowing cold. I said something to my wife about it then it started blowing cold again. Less than a minute later is was back to not blowing cold. My wife looked at the dash and said “Does that have anything to do with it?” She pointed at the temp gauge and it was up to where I put the green line in the picture. By the time I stopped at Costco 2-3 minutes later, it had cooled off a bit and was holding just above the red mark. Driving speed when the gauge was reading hot was about 70 MPH so air flow wasn’t a problem. At no point was steam coming from the car. No boiling sound from the reservoir. No smell of coolant. Since it wasn’t boiling over, I just let it sit for the 30 minutes we were in Costco. We decided to go to our oldest son’s house 2 miles away where we could get water for the car if need be. All the way to my sons and halfway back home, the temp gauge read about where the yellow mark is. At that point, the temp rose just a bit to where I put the red mark. It’s about 10 minutes from where I get off the interstate to my driveway. By the time I got home, the temp gauge was reading where it is in the picture. At no time did steam come from the care, boiling sounds, or the smell of coolant. Any ideas?
