Default Erratic temperature gauge
I have been breaking in my car this weekend. It has a 482 aluminum engine. I am puzzled by how erratic the temperature gauge is. When going down the freeway at 2200 rpm in fifth gear the temperature gauge will be at 90°C and then jump 110°C and then fall back. I can't figure out why the temperature would change back and forth so rapidly. It seems like the gauge should gradually move up and gradually move down. Any ideas?
