Don't rely on the dummy gauge on the instrument cluster either, if you want to visually monitor the engine temperature you need to either use an obd ii scantool like a scangauge, or to run the car in test mode on the instrument panel center display. (Hold down the left ok button for at least 5 seconds prior to turning the car from off to run, hold it while starting the car until the screen says TEST). Scroll down or up through the various test menus until you see the coolant temperature sensor reading. It should start off cold, somewhere near 14-25C or less and rise to normal operating temperatures of around 90-97C eventually. 97 is usually slightly on the warm side, and I only have seen it in brief intervals on stop and go freeway driving while the car was warming up due to the acceleration and deceleration.
