1998 GMC Sierra 1500 - Temp climbs to 125
Temperature gauge has been climbing in the cap where the pump seems to kick in. Now it sits around 125 until I can push the speed to ~80km/h for a minute or so. After that the temperature doesn't hit 125 any more for the rest of the trip. This has been occurring during the heat wave in Southern Ontario, not sure if the limit was rising before that.
