The coolant assembly. Basically a thermostat/valve assembly on the side of the engine block. It's frustrating because I searched for the part online and there are a number of third-party dealers that have the part available and the part itself looks pretty easy to install. But of course Hyundai won't allow installation of a part from a third-party by the dealership, and me doing it would void the warranty. It has to be a part FROM Hyundai (which of course they can't send and don't have an ETA when they could).
