Hey guys I was driving along a road yesterday after about 20 minutes of driving. The temperature gauge spiked to the red zone and my dash started beeping because the engine temp was too high. I was on a busy road so I slowed down and pulled into a side street. The temperature gauge then went back to half way, where it usually sits, and stayed there until I turned the car off. I then drove another hour and a half with no issue. What could be the problem?
