Product Details

Koyorad Radiator A13571 is engineered as an OE equivalent replacement for cooling-system service. The core measures 23.625 inches high, 14.125 inches wide, and 1.3125 inches thick, giving it the proportions needed for the listed BMW diesel applications. Koyorad uses its manufacturing experience to produce replacement radiators that follow the expected fit and function of the original part. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Coolant temperature control issues caused by a worn radiator.
• Leaks from cracked tanks or aging core materials.
• Restricted heat exchange from internal corrosion or blockage.
• Cooling-system service needs on BMW 328d and BMW 328d xDrive models.
