Koyo Radiator - S-Series: S Series radiators incorporate the same technology as Koyo's OE aftermarket replacement product line; Molded plastic tanks with a copper core in place of aluminum. Due to the excellent heat exchange properties of Copper, Koyorad S Series radiators are a great choice for a light tuned car, when it will not be at speed for extended lengths of time.
All Koyorad S Series Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans.
Precise Tube and Fin Alignment
Construction under strict quality control and solid boxing result in tubes with optimal coolant flow and fins with highly efficient heat transfer
Tubes, Fins, Headers and Brackets are brazed in a state-of-the-art Nocolok furnace, bonding all components to resist damage from vibration, road debris, and the elements.
Billet Filler Neck
Precision machined billet filler necks are incorporated on each Koyo radiator for strength, durability and better sealing.
OE Specific Mounting and Hand Crafted Heliarc Welds
Koyo incorporates application specific mounting locations for all fan shrouds, inlet/outlet hoses and top/bottom mounting pins, ensuring quick and pain-free installs. Each Koyo All Aluminum Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminum to aluminum bond, to mate all components.
