80q coolant flush/refill worry

[walian at att.net]

Megan,

  If the car was not overheating before your flush I would say you have air in the coolant system. Once you get the air flushed out all should be well. I dont know the exact procedure for your car. I uasually just run the car with the radiator cap off for a while.
