High-Performance 55MM 3-Row Aluminum Radiator with Fan Shroud & Thermostat Relay Kit for 1967-79 GMC Chevrolet C/K C10 C20 C30 K10 K20 Pickup & P/G Series Van - Enhanced Cooling for Hot Weather & Heavy-Duty Towing

A sincerest greetings from CoolingSky! This aluminum radiator is designed to provide maximum cooling efficiency to prevent premature engine failure. Its light-weight,and high heat transferring aluminum features a tube and fin design that,dramatically increases surface area that enables the heat to dissipate more efficiently. This Aluminum Radiator is at least 35% more efficient than stock ones. Most importantly,it has a much higher capacity for coolant than stock ones,which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications. Built with high density multi-louvered fins for maximum cooling efficiency, to ensure durability in extreme weather Use of Nitrogen during welding in the furnace for maximum strength Has undergone thorough inspection to guarantee consistent, lasting performance Vehicle test-fitted prior to market release, ensuring perfect drop-in fit All radiators includes black high-pressure cap and brass petcock/drain plug Overall size: 19-1/4" x 33-7/8" Core size: 17'' x 28-1/4" Inlet: 1-1/2" Outlet: 1-3/4" Trans cooler thread size: G1/4 The fan will continuous improve engine cooling functions and the overall performance of your vehicle. All fan shrouds are obviously lighter than your stock one, and are a direct fit the radiator. They will notably improve engine cooling performance by delivering more air to the radiator and driving out excess heat.
