Heavy Duty Radiator Overview

The Spectra 2001-1737 is a heavy duty radiator built for direct replacement applications where OE-level cooling performance matters. It is listed for Freightliner MT45 and MT55 models, with fitment that also includes the 2011 Freightliner MCL.

Key Features

  • Heavy duty radiator construction for cooling system replacement.
  • Engineered to meet or exceed original equipment performance targets.
  • Supports both engine and transmission cooling functions where specified.
  • Fits Freightliner MT45 and MT55 applications with OEM frame reuse on listed vehicles.
  • Part number 2001-1737 for accurate ordering and cross-reference matching.

Detailed Description

Spectra Premium uses engineering, manufacturing technology, and quality control processes to produce radiators that match the performance expectations of the original equipment they replace. For the Freightliner MT45 and Freightliner MT55, this radiator is listed with application-specific notes that include OEM frame reuse on certain model years and transmission oil cooler provisions on the earlier fitments. The 2001-1737 radiator is also cataloged for the 2011 Freightliner MCL with the same core and connection details shown in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 20011737, 238789) for the same application.

What It Helps Address

  • Overheating caused by a worn or inefficient radiator.
  • Cooling system leaks from an aging radiator assembly.
  • Reduced heat transfer in heavy duty service.
  • Transmission cooling concerns on listed applications with TOC provisions.
  • Replacement needs when the original frame must be reused.

Installation Notes and Tips

Verify the core dimensions, inlet and outlet sizes, and transmission oil cooler details against the existing unit before installation. Some listed applications require reuse of the OEM frame, and the fitment notes should be checked carefully for the exact model year. Confirm the part number 2001-1737 before ordering to match the correct Freightliner MT45, Freightliner MT55, or Freightliner MCL application.

Quality Assurance

Spectra Premium states that its heavy duty radiators are produced with engineering, manufacturing technology, and quality control intended to meet or exceed the performance of the original equipment they replace.
