Hi friends, I have a 2010 Mazda 3 2.5L and noticed my engine coolant will climb while idling or at low speeds. I have never had the engine temp lamp kick on, but I've seen the coolant temperature hit 220F in Torque. I also live in an extremely hot area during summer (average day is about 105F with spouts up to 115F). Should there be cause for concern here when I see the coolant temp climbing from 180F while idling or at low speed? I'm not much of a car guy, and I don't really know what temperature my concern should be warranted. Thanks for the help.
