Corksport Coolant Tank for 2010-2013 Mazdaspeed 3 / 2004-2013 Mazda 3

Many years ago, CorkSport released a coolant reservoir that we ended up discontinuing. But you asked for it to come back and we listened! Say hello to the new and improved coolant reservoir for the 2004-2013 Mazda 3 and the 2010-2013 Mazdaspeed 3. We went back to the drawing board to optimize the design and manufacturing to ensure the best tank for your 3. With a proper internal baffling system and durable aluminum structure, it is a welcomed replacement to your yellowing, rotting plastic tank. Finished in a wrinkle black powder coat, it will hold up to the test of time and look great while doing it! Check out the info below for full details and more pictures!

Optimized Design:

The CorkSport Aluminum Coolant Reservoir is designed to be the best coolant tank for your 3. As the Mazda 3 and MS3’s get older, the OEM plastic coolant tanks become more and more prone to failure. Aluminum is a much more reliable material for the constant pressure and temperature changes while also being resistant to any chemicals in your coolant. To really ensure OEM functionality, the CS Coolant Tank has internal baffling just like the OEM tank. This keeps air bubbles from entering the cooling system during aggressive driving!

Appearance Bonus:

The CS coolant res replaces your ugly, yellow OEM coolant tank with a sleek design that looks much better under the hood of your Mazda. The wrinkle black powdercoat looks at home in any engine bay, whether you are mostly stock or have custom powdercoated components all over. We even hid the mounting locations for an extra clean look.

Usability Focused:

Upgrading to the CorkSport Coolant Tank does not come with the headaches that universal kits have. All the OEM coolant hoses are retained with no modifications needed while fill level is easily monitored with the sight tube at the front of the tank. We also switched to a more traditional radiator cap. This ensures great functionality and appearance, plus the ability to upgrade to a higher pressure cap if desired. Finally, the included overflow hose can easily be adapted to a catch tank if you’re racing your 3 in a series that requires it!

Materials and Manufacturing:

Each CorkSport Coolant Reservoir is manufactured from laser cut and precision formed 11 gauge Aluminum. Each component is TIG welded together for the best appearance and strength. The included cap, sight tube, and fittings are all optimized for use under pressure and with the chemicals in automotive coolant. Finally, once assembled, we pressure test every tank to ensure there are no leaks.
