In '12 Nissan added a pressurized and larger radiator overflow tank which increases the circulating volume of the coolant system. The oil cooler and the pressurized tank were to address the well know overheating issue on our cars. My '13 runs around 200 degree in DD and 220 with spirited driving. You still need an oil cooler on '13s for track work, but on the road most folks find the cooling upgrades Nissan added sufficient.
