Moroso 02-07 Subaru WRX/Sti Coolant Expansion Tank - Direct Bolt-In Replacement

This Moroso coolant expansion tank is a direct bolt-in replacement for your 2002-2007 Subaru WRX or STI. It's designed to be a straightforward swap for the factory plastic tank, which can become brittle and prone to cracking over time, leading to coolant leaks and potential engine overheating. This tank helps ensure your cooling system stays sealed and functions as it should.

Moroso builds this expansion tank from durable aluminum, offering a more robust solution than the original plastic component. The aluminum construction is less susceptible to the heat cycles and environmental factors that can degrade plastic over the years. Its design aims for a clean installation, meaning you won't need to modify your existing cooling system hoses or mounting points. This makes it a solid option for WRX and STI owners looking to upgrade a common failure point in their cooling system.
