Carbing Okuyama Aluminum Radiator Coolant Header Tank - Honda FL5 Civic Type R

The Okuyama Carbing Aluminum Radiator Reservoir Tank is engineered to optimise cooling performance and reliability in the Civic Type R FL5. Inside the radiator, a special dividing plate efficiently removes air bubbles from the coolant, ensuring stable temperatures and consistent radiator efficiency even under heavy load.

Constructed from lightweight and durable A5052 aluminum, the reservoir tank resists corrosion and heat stress far better than the stock plastic unit. Its anodised surface finish is built to withstand the harsh environment of the engine bay, where temperature fluctuations are extreme.

Installation is straightforward with a bolt-on design that directly replaces the factory tank. To further enhance cooling efficiency, each unit is supplied with a high-pressure radiator cap.
