No ! But it’s running very hot , to the point I can’t touch nothing under hood because extremely hot. Up until two weeks ago it had never gone above 85, now it’s at 100 after ten minutes of driving even when cold outside. I’m in Los Angeles and never went above 85 . Also same time my heater only blows cold air out of side vents. Replaced coolant, thermostat, coolant sensor. Still the same. Any help is much appreciated. Thank you
