Coolant leak only when shutting the car off.

It's a good idea to stick with whatever is already in there. Some types are not compatible. Not a recommendation, just the first hit: 2012 Nissan 370Z Antifreeze & Additives

Maybe I'm missing some info but this doesn't sound completely right. Is this leaking even if cold? Or only after fully warm? Sounds odd that it is not happening while running and only after being off. There is a bit of a back up after shutting down sometimes as the pump is no longer moving coolant but still sounds odd. Easy enough to have the cap tested. If cap passes and/or it is happening even cold/warm (not hot) I would have the engine block checked.

is there any oil in coolant, possible head gasket?
