What temp does your vehicle run while idiling after 30 minutes of driving in stop and go traffic? My denali went up to 220 today.I checked the coolant and it was full. I am just curious because my lexus runs alot cooler than my denali. I hate having my truck at the dealership cause they like to mess with my tv's and system. I would rather fix it myself if I have a problem. Just curious....
