The stock Coolant Overflow Tank may do its job, but it's far from ideal. Made from cheap plastic, it not only lacks aesthetic appeal but can also be prone to cracks, especially when exposed to extreme conditions due to spirited driving or harsh climates. Furthermore, its awkward shape can disrupt the engine bay's aesthetics. Enter the COBB Coolant Overflow Tank for your VB WRX!

Construction: Crafted from welded aluminum, the COBB Overflow Tank boasts a generous 1.1L capacity, surpassing the capabilities of the OEM tank. Both internal and external tank surfaces feature anodized finishes, ensuring long-lasting durability. The fill and vent tubes are meticulously welded to create a leak-free structure. The fill tube extends to the reservoir's bottom to prevent air ingestion as the coolant level expands and contracts. The vent tube exits through the tank's bottom and can be routed out of your vehicle with the included silicone tubing. An integrated dipstick, anodized in striking red, provides a quick reference for coolant levels.

Caps and Finish: The main reservoir cap fits snugly and is made from injection-molded plastic. A blue anodized billet cap beautifully completes the included fill tube designed for windshield washer fluid.

The COBB Coolant Overflow Tank is a visually appealing solution to enhance the otherwise mundane engine bay of your VB WRX.
