Overflow Reservoir Versions

Nissan transitioned from a standard non-pressurized overflow reservoir to a pressurized version in May of 2012, which is in the middle of the 2012 Model Year (which is why you may see some inconsistency in year ranges across related parts). The non-pressurized version puts the pressurized "radiator cap" on the filler neck, and uses a simple plastic cap on the overflow reservoir tank. The pressurized version uses a "dummy" radiator cap on the filler neck, and a pressurized cap on the overflow reservoir tank. If you're not sure which variant your car uses, please use the photo below as a reference to compare against your car.
