Spectra CU13758 Radiator for Enclave and Traverse

The Spectra CU13758 radiator is built for OE-style durability and cooling performance in select Buick Enclave and Chevrolet Traverse applications. It combines an aluminum core with plastic tanks and includes an internal transmission oil cooler for vehicles that rely on integrated cooling.

  • Cross flow design with top-right outlet and bottom-left inlet
  • Internal transmission oil cooler included
  • Transmission oil cooler uses plate-style construction
  • Core dimensions: 30.6875 in. height, 25.6875 in. width, 1 in. thickness

Detailed Description

Built for the cooling demands of modern crossover platforms, the Spectra CU13758 radiator is engineered to match OE durability expectations while supporting engine temperature control and transmission fluid cooling in one assembly. The radiator uses a cross flow layout, 1-row core, and integrated transmission oil cooler with plate-style construction to support vehicles equipped with factory cooler routing. This part number, CU13758, is a practical replacement choice for drivers servicing a Buick Enclave or Chevrolet Traverse cooling system.

This part cross-references BBB Industries 13758 and Bosch 13688 for the same application.

What It Helps Address

  • Overheating caused by a restricted or leaking radiator
  • Transmission temperature issues related to a failed internal cooler
  • Coolant loss from cracked tanks or damaged core seams
  • Reduced heat transfer from age, corrosion, or debris buildup
  • Cooling system service needs on Buick Enclave and Chevrolet Traverse models

Installation Notes and Tips

Verify inlet and outlet locations, header dimensions, and cooler fitting type before installation. The CU13758 uses a bottom-left inlet, top-right outlet, and OCAD38 by HF transmission cooler fittings, so matching the factory configuration is important for a proper replacement. Always inspect hoses, clamps, and coolant condition during radiator service, and confirm the vehicle’s cooling system is fully bled after installation.

Quality Assurance

Spectra Premium radiators are built to meet the durability and performance expectations associated with OE replacement cooling components. The CU13758 is designed as a direct replacement radiator for confirmed Buick Enclave and Chevrolet Traverse fitments.
