We call the red Dex-Cool "Dex Mud" because that's what it can turn into. The green will be fine but it can't be mixed with the red. The system should have been flushed when the change was made.

First check that the radiator fan is turning on. Check the fins on the radiator to be sure they aren't corroded away.
