Weapon R 03-06 350z Aluminum Coolant Overflow Tank (DOES NOT FIT HR MOTOR)

Crafted from aluminum, this coolant overflow tank from Weapon R is built to replace the factory plastic unit on your 2003-2006 Nissan 350Z. The stock plastic tanks can become brittle over time, leading to cracks and coolant leaks. This aluminum version offers a more durable solution, helping to ensure your cooling system stays sealed and functions properly. It's designed to fit directly in place of the original tank, making the swap straightforward.

This tank is specifically made for the 350Z models from 2003 through 2006. It's important to note that this tank will not fit the later 'HR' engine models. The aluminum construction not only adds durability but also gives your engine bay a cleaner, more finished look compared to the often-discolored factory plastic. It’s a solid option if you’re looking to upgrade a weak point in the cooling system or simply want a more robust replacement part.
