3-Row Downflow Radiator

The Champion Cooling CC374 is a 3-row, all-aluminum radiator engineered for enhanced cooling performance in downflow systems. With core dimensions measuring 17 1/4" in height by 25 7/8" in width, it offers substantial cooling capacity, advertised to support vehicles up to 650 horsepower. The radiator features a downflow design with the inlet positioned on the driver's side and the outlet on the passenger's side, ensuring compatibility with specific engine bay configurations. Constructed entirely from aluminum, the CC374 offers benefits such as lighter weight and superior heat dissipation compared to traditional copper or brass radiators. Its 3-row core design with 0.75" tubes provides increased surface area for more efficient heat exchange, crucial for maintaining optimal engine temperatures under demanding conditions. This radiator is a direct fit for select 1968-1974 Mopar vehicles, including the Dodge Coronet and Plymouth Roadrunner, and is also listed for specific Dodge Challenger models from 1970. While designed as a direct fit for many applications, some users have noted that minor modifications or editing for fitment may be required in certain installations, particularly concerning transmission line fittings. It is recommended to verify clearance for electric fans, as the radiator's overall thickness can impact fan mounting. The CC374 does not include a thermostat relay kit, which may need to be purchased separately. For optimal performance and longevity, it's advised to use a 50/50 distilled water and ethylene glycol antifreeze solution for coolant.
