Just curious. When I'm driving along the highway at steady speeds, the engine temp stays a little over 80 degrees. When I am stopped for an extended time, say at a stoplight or Tim Hortons drivethru, the temp goes up to about 105 or 110. But then when I start driving it goes back to a little over 80. Yes the fan kicks in and does drop it somewhat. The rad is about 1 year old. Coolant is recently changed. Any ideas if this is normal?
