DENSO Auto Parts Radiator P/N:221-9247
DENSO Auto Parts 221-3701 radiator for the 1999-2001 Hyundai Sonata V6 2.5L, the 1999-2005 Sonata 4-cylinder 2.4L, the 2002-2005 Sonata V6 2.7L and other vehicles passes engine heat from the coolant to the air moving through its core. DENSO builds it with a First Time Fit philosophy, and its tanks, core dimensions and materials meet rigid OE manufacturer standards.
Overheating, a temperature gauge that keeps climbing, or coolant dripping beneath the front of the car can mean the radiator is leaking or clogged. A stuck thermostat, a weak water pump, a worn radiator cap or a split hose can be behind those signs too, so track down the real source before you buy.
Beyond the Sonata, this radiator fits the 2001 Kia Optima V6 2.5L, the 2001-2006 Optima 4-cylinder 2.4L and the 2002-2006 Optima V6 2.7L. Each car takes one radiator.
