DENSO Auto Parts Radiator P/N:221-9166
DENSO Auto Parts 221-3242 radiator for the 2009-2011 Acura TL V6 3.5L carries engine coolant through a thin-tube aluminum core to shed heat. Engine cooling and function depend on the radiator, and this 2009-2011 Acura TL V6 3.5L radiator is a new part.
Coolant leaks, wet spots along the tanks or an engine that runs hot can be signs of a failing radiator. Before replacing it, and only with the engine off and cool, look over the hoses, clamps and radiator seams for crust or dampness, since a leak elsewhere in the cooling system can look much the same.
This radiator is a direct-fit replacement for the 2009-2011 Acura TL V6 3.5L, and that car takes one.
