Hey Mopar Family, I have a 2008 Charger se sadly not the Hemi. My coolant temperature guage stays right on the middle but will drop a bit when on the highway or at long time idle such as traffic or a drive thru. I bought a USB obd2 reader and my temperature reads 220f on stop and go traffic and around 190-200 while driving. Is this normal ? Should my needle be fluctuating? Thanks! Any info would help! I have changed the radiator,thermostat, coolant air bleeder,coolant sensor, flushed, and currently using the HOAT coolant. Both my fans only turn on when the car is 217-220f. I noticed using the heater cools down the car.
