Did you have the condition before the coolant flush? Did you bleed the system properly when filling?

Those trucks are known for damper door actuator issues. Have you heard any weird clicking in the dash area behind the radio?


If you did not have the issue before flushing the system it's probably not a damper door issue. In that case I am with Tom about making sure you blead all the air out of the cooling system.
