DENSO Auto Parts Radiator P/N:221-9331
$209.99
Keep engine temperatures in check and coolant flowing with the DENSO Radiator 221-9331. It drops in as a direct-fit replacement for the 2012-2017 BMW X3 and the 2015-2017 BMW X4, transferring heat from the circulating coolant to the passing air so the cooling system can hold operating temperature.
- Core cooling: Routes hot coolant through the radiator core, where airflow draws heat away and returns cooler coolant to the engine.
- Direct-fit application: A direct-fit replacement for the listed BMW X3 and X4 vehicles.
- System component: Works with the water pump, thermostat, hoses, and cooling fan to manage engine heat.
Common signs the original radiator may need replacing include coolant leaks, engine overheating, a low-coolant condition, or internal clogging that restricts flow. If a failed or leaking radiator is the cause, this unit replaces it. Diagnose the source of any overheating before replacing, since these symptoms can have other causes.
