Removing all the old coolant from 3.6

[Danarch]

I plan on replacing the thermostat housing on my wife’s JKU. Does anyone know if there is a drain plug on the engine block? The TJ (4.0) has a drain plug and when removed a fair amount of additional coolant drains out. I’d like to get as much of the old coolant drained as possible.

Did you ever find out if there is a drain plug on the engine block?

No, but I haven’t done it yet. T-state is sitting in the garage. Just been busy.
