OE-Style Radiator for BMW Cooling Service

This OSC Premium New Automotive Radiator is built for direct replacement service on select BMW applications, including 1995-1998 BMW 740iL, 1995-1998 BMW 750iL, and 1997-1998 BMW 528i, 540i, and 740i. Part number 1401 is engineered around OES form and function to support proper fit, cooling performance, and dependable operation.

With a crossflow design, plastic tanks, and a premium PA core, this radiator is made for vehicles that need a precise OE-style cooling solution. The 1-1/4 inch core thickness, 25 1/2 inch core height, and 17 1/4 inch core width help match the original layout on the listed BMW models.

Detailed Description

OSC designs this radiator to follow original equipment form and function while adding durability-focused improvements. Premium-grade tubes, fins, headers, tanks, and related components are used to support consistent cooling performance, and the radiator is assembled with factory-spec component fit and torque. The unit is also engineered with enhancements such as increased fin density and a thicker core to address heat load in higher-mileage BMW cooling systems. Part number 1401 cross-references Spectra Premium CU1401 for the same application.

Common Cooling Issues It Can Address

  • Cracked or leaking radiator tanks
  • Restricted coolant flow from an aging core
  • Overheating caused by reduced heat transfer
  • Cooling system failure on high-mileage BMW 740iL and 750iL models
  • Fitment problems from a damaged or incorrect replacement radiator

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and cooler configuration before installation on your BMW 528i, 540i, 740i, 740iL, or 750iL. This radiator is a crossflow unit and does not include an engine oil cooler, transmission oil cooler, or cap. Inspect hoses, clamps, and surrounding cooling system components during replacement to help prevent repeat failures.

Quality Assurance

Each OSC radiator is pressure tested during production, with cooler circuits checked before tank installation and the completed assembly tested again after build. The design is intended to meet OE-style cooling requirements for the listed BMW applications while maintaining proper fit and function.
