I was driving the other day and noticed the AC started blowing warm air and then the temperature gauge was near the red zone. After I stopped driving, I noticed the coolant tank was low. I hadn’t noticed any leaks before, but it was low so I added more antifreeze assuming that was the issue. The next day, I’m driving again and the temperature keeps getting hotter and the AC starts blowing warm air...this time the temp gauge is topped out. I get home quickly and turn off the car and then steam and antifreeze start spewing out all over. The fans are on and working when I pop the hood. So I know it’s not a coolant level issue and it’s not a fan issue. I’m dreading it being a head gasket issue. What else could be the culprit? I’m not a very skilled mechanic, but I’d do easy to easy/moderate level work to save thousands of dollars.
