Spectra Premium CU2491 radiator for the 2001-2005 Cadillac DeVille V8 4.6L and other vehicles moves hot coolant through a cross-flow core to shed engine heat. Coolant flows in at the top right and out at the top left.
Coolant seeping from the tanks or core, a falling coolant level or a temperature gauge that climbs can mean the radiator is leaking or clogged. A failing thermostat, water pump, radiator cap or coolant hose can be behind these signs too, so track down the actual cause before you buy a radiator. The cooling system uses a single radiator.
This radiator fits the 2001-2005 Cadillac DeVille V8 4.6L and the 2001-2003 Oldsmobile Aurora V8 4.0L. Its structure and design are built to the durability and expectations of the OE radiator.
