Detailed Product Overview

Part number 13613C is a radiator assembly engineered for cooling-system replacement on 2017-2026 Cadillac XT5, 2020-2025 Cadillac XT6, 2019-2026 Chevrolet Blazer, 2017-2023 GMC Acadia, and 2017 GMC Acadia Limited applications. The aluminum core helps transfer heat away from the engine coolant, while the integrated transmission oil cooler adds fluid temperature control for vehicles equipped with automatic transmission cooling through the radiator. This part cross-references Spectra Premium CU13613 and DENSO Auto Parts 221-9603 for the same application.

What This Radiator Helps Address

• Engine overheating caused by a restricted or leaking radiator
• Transmission fluid temperature rise when the cooler circuit is compromised
• Coolant loss from cracked tanks or damaged core seams
• Reduced heat dissipation from a clogged or corroded radiator core
• Cooling-system service needs on high-mileage Cadillac XT5, Chevrolet Blazer, and GMC Acadia models

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler fitting style before installation. This radiator uses quick connect transmission cooler fittings with an 11.81 in. distance between fittings and a 0.37 in. fitting diameter. Flush the cooling system, inspect hoses and clamps, and confirm the replacement matches the vehicle’s original cross flow layout.
