No, it'* straight through. I'm dumping the quick-disconnect for a straight capped fitting. Simpler, shorter, but I'll need two wrenches to drain it.
Not much should leak out after pulling the cap if the upper plug is still in place. But if you remove that 45° fitting, it'll dump. It'* a much larger diameter.
This series of fittings also will act as a 'debris trap' of sorts as the particulates settle after turning the car off.
