DENSO Auto Parts Radiator P/N:221-9087
DENSO Auto Parts 221-3239 radiator for the 2005-2008 Acura RL V6 3.5L carries heat out of the engine coolant through a thin-tube aluminum core. Its tanks, fin pitch, core dimensions and materials are built to OE manufacturer standards.
A failing radiator can show up as an engine running hotter than normal or a temperature gauge that climbs. With the engine off and cool, look over the core and tanks for wet spots, crusty residue or bent fins. Overheating can also come from the thermostat, the cooling fan or a leak elsewhere in the system, so pin down the source before you swap the radiator.
This radiator fits the 2005-2008 Acura RL V6 3.5L, and the car takes one. DENSO makes it under its First Time Fit philosophy for OE quality and performance.
