Accidentally overfilled the coolant overflow tank in the FD
Accidentally overfilled the tank by a lot. I did a coolant flush and was tired and added too much coolant to the overflow tank. Is there a way I can maybe drain it without taking a lot of things apart?

Starting with the engine, radiator, heater core and all coolant hoses/plumbing fully topped off with coolant and burped of all air, and a proper working pressure cap, as coolant gets hot driving it will expand and increase pressure up to the cap's rating. Typically if the system is healthy it wont exceed that cap pressure in operation, but if it does, the cap opens and coolant can now flow to the overflow tank. More commonly, when you shut the car off hot, since the coolant is no longer flowing, the engine heat soaks, coolant temp/pressure increases and some coolant will flow to the overflow tank. As the engine cools down, it creates a vacuum in the engine's coolant system, and the coolant is pulled from the overflow tank back into the engine, replacing what was sent to the overflow tank.
