Our Nissan S14 Coolant Overflow is a great way to clean up your engine bay and free up extra space! This tank offers a sleek design that bolts to factory studs on the radiator support in seconds. The side 5/16" barb will be connected to the radiator, while the bottom fitting will expel any excess fluid during coolant expansion. An internal tube runs from just below the cap, down to the bottom fitting allowing for minimal coolant loss while driving!
