I've changed the coolant on my GT four times, and I am not aware of a way in which the Radkitplus can be used to remove the coolant. I have only used it to remove the air from the systems before I refill them.Can the Radkitplus be used to remove the old coolant? Thanks.
To drain both cooling systems, I open the radiator and intercooler drains at the front of the vehicle and then remove the two threaded plugs in the engine block. The front splitter and both pans under the engine will need to be removed to gain access to those drain points.
