Koyorad continues to improve upon cooling performance for EG and EK chassis Honda Civics and is proud to announce a brand new full-length aluminum racing radiator for these “golden era” favorites. This application was taken from the Koyorad Japan catalog, proven for nearly a decade in Japanese N1 and Honda VTEC One Make Racing and is now available in North America. Designed for the serious race car, this radiator will not fit vehicles equipped with air conditioning (AC). By utilizing the space for the AC condenser, the radiator core surface could be increased by over 100%, which boosts the cooling system’s heat capacity and endurance in extreme conditions. The original radiator fan shroud and OEM DOHC radiator hoses can be used, requiring no modifications for installation. Users may install an aftermarket coolant temperature gauge with the optional 1/8PT sensor port, conveniently located directly on the upper radiator tank which eliminates the purchase of a sensor hose adapter. Koyorad’s advanced engineering and design, proficiency in furnace brazing, and triple pressure testing for quality has earned their excellent reputation in performance cooling worldwide.

Features:

• High Density 36mm HyperCore
• Over 100% increase in core surface area over standard half size radiator
• 32mm inlet and outlet for DOHC Honda engines.
• Easy installation, no modifications necessary on vehicles without AC
• Optional 1/8 PT sensor port for aftermarket temperature gauges
• Compatible with OEM radiator fan shroud
• Top header plate stamped with Koyorad logo
• Triple pressure tested during manufacturing process for quality

Part# VH0812N1

Applications: 92-00 Honda Civic 1.6 DOHC Manual Transmission, not equipped with AC

Koyorad is proud to announce an all-aluminum high-performance radiator for the 1^st Generation (1995-2004) Toyota Tacoma V6 4x4 and PreRunner V6.  Koyorad’s high density HyperCore measures 36mm thick, a 44% increase over the OEM unit which boosts the cooling system’s heat capacity and endurance under extreme use.  Designed for serious off-road enthusiasts, the internal automatic transmission (AT) cooler has been purposefully omitted.  This allows for 2 inches of additional approach angle with AT equipped trucks.  An external transmission cooler (not included) will be necessary, which allows for physical and visual inspections of the cooler itself and can be upgraded to offer improved transmission performance in the field.  Without an internal AT cooler, radiators have zero risk of catastrophic engine and drivetrain damage from coolant and transmission fluid breech.  Advanced engineering and design, impeccable TIG welds, proficiency in furnace brazing, and triple pressure testing for quality has earned Koyorad the excellent reputation in performance cooling worldwide.

Features:

• All-aluminum, 36mm high density HyperCore
• Gain 2 inches of additional approach angle on AT trucks
• No internal AT cooler (eliminates the chance of coolant and transmission fluid breech on AT vehicles)
• TIG welded and furnace brazed construction
• Triple pressure tested during the manufacturing process
