Detailed Description

OSC designs this radiator to match original equipment form and function while using premium materials and production controls. The core uses aluminum construction with cadmium-plated tubes inside and out, and the unit is built with a concentric transmission oil cooler where originally equipped. The radiator is also engineered for multi-fit use without changing the look or fit of the cooling system, making it a practical replacement for Nissan Murano cooling service.

The 2578E radiator is intended for vehicles that require a downflow layout and a transmission cooler integrated into the radiator assembly. Its factory-style dimensions and fitted components support a clean installation and consistent cooling performance. For buyers searching for a Nissan Murano radiator, 2578E, or a direct replacement radiator for 2003-2007 Nissan Murano, this unit aligns with the original design requirements.

What It Helps Address

• Coolant leaks from a worn or damaged radiator
• Reduced cooling efficiency from aging core materials
• Transmission heat management issues tied to a failing cooler
• Fitment problems caused by non-OE-style replacement parts
• Corrosion-related radiator deterioration over time

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and transmission cooler configuration before installation. This unit is built for applications that use a concentric transmission oil cooler and a downflow layout. The product information states that necessary fittings or hardware are included, and the radiator is pressure tested during production for leak verification.

Quality Assurance

OSC pressure tests each radiator during production, including testing before assembly and after final assembly. The design uses premium-grade components and cadmium-plated tubes to improve durability and reduce premature failure. Part number 2578E is engineered to meet original equipment cooler design requirements where originally equipped.
