Overheating in traffic but fine on highway – fan or radiator?

PreviousPage 2 of 2

Your symptoms point first toward an airflow problem at low speed, especially the cooling fan, fan control/relay, or restricted radiator airflow. The fact that it returns to normal once highway airflow increases makes the fan worth testing before replacing the water pump. A thermostat or coolant-flow issue is still possible, but I’d verify the fan’s operation against actual coolant temperature and check radiator airflow before spending money on parts.

I’d also have the system pressure-tested, inspect the radiator/condenser for blockage, and check for trapped air or a weak water pump if the fan tests good.

And don’t keep driving it into the red—Dodge specifically warns that driving with an overheated cooling system can cause damage
