What is RadiatorRadiator is a component of a vehicle's cooling system that is responsible for dissipating heat from the engine. It is typically located at the front of the vehicle and consists of a series of tubes through which a coolant is circulated. When coolant passes through the radiator, it is cooled by the air flowing over the radiator fins. the cooled coolant is then circulated back to the engine to absorb more heatFitmentfor Chevyfor Silverado 1500 4.3L 2007-2012 2014-2018for GMCfor Sierra 1500 4.3L 2007-2018SpecificationInlet / Outlet Diamenter: 1-5/16" / 1-9/16Part Number52462549,52462548,CU1532,52462546,52462545Core Dimensions26-1/4" W X 14-7/8" H X 1" DIncludes1 X RadiatorColorBlack / MetallicMaterialsPlastic / AluminumRows1StyleOEFeatureThis Aluminum Core Radiator Is Designed to Provide Maximum Cooling Efficiency to Stop Premature Engine Failure.
