he OEM Coolant Overflow Tank does its job well enough but the cheap plastic material is ugly and can potentially crack over time, especially when exposed to extreme heat via hard driving or extreme climate. Its shape is also clumsy and obtrusive. Enter the COBB Coolant Overflow for your VB WRX!
Constructed of welded aluminum and carrying a capacity of 1.1L, the COBB Overflow offers more capacity than the OEM tank. Internal and external anodizing of the tank ensures a long lasting finish. Internally welded fill and vent tubes provide a leak-free construction. The fill tube extends to the bottom of the reservoir to prevent air ingestion as coolant level expands and contracts. The vent tube exits through the bottom of the tank and can be routed out the bottom of your car with included silicone tubing. An integrated dip stick is anodized red and allows for quick reference of coolant level.
The main reservoir cap is a snug fitting injection molded plastic. A blue anodized billet cap finishes off the included fill tube for windshield washer fluid.
The COBB Coolant Overflow is a sharp solution to an otherwise bland component of your VB WRX's engine bay.
