DENSO Auto Parts Radiator P/N:221-3237
$261.99
Keep engine temperatures in check with the DENSO Auto Parts Radiator 221-3237, a direct-fit replacement for the 2007-2013 Acura MDX and the 2010-2012 Acura ZDX. It handles the radiator's core job — moving heat from the hot coolant into the passing air so your engine stays within its normal operating range.
- Cooling function: Circulates engine coolant through the core, where airflow carries heat away to help maintain proper operating temperature.
- Direct-fit replacement: Serves as a replacement radiator for the listed Acura applications.
- Signs it may need replacing: Visible coolant leaks, rising temperature gauge or overheating, and corrosion or clogging that reduces cooling. If a failed radiator is the cause of these symptoms, this unit replaces it — diagnose the cause before ordering.
Because the cooling system is under pressure, always let the engine cool fully before servicing, and refill with the correct coolant type and mixture per the vehicle service information.
