DENSO Auto Parts Radiator P/N:221-9087
DENSO Auto Parts 221-3169 radiator for the 2006-2015 Lexus IS350 V6 3.5L and other vehicles releases engine heat from the coolant into the air. DENSO builds it with a First Time Fit philosophy and OEM quality and performance.
Coolant leaks, an engine that runs hot or a dropping coolant level can mean the radiator has failed. A thermostat, water pump, radiator cap, hose or cooling fan can be behind those signs too, so find the cause before you buy a radiator.
This is a direct-fit radiator for the 2006-2013 Lexus IS250 V6 2.5L and the 2006-2015 Lexus IS350 V6 3.5L.
