Aluminum Radiator for GMC Yukon (2015-2019) 5.3L 6.2L

High-Efficiency 3-Row Aluminum Radiator for 2015-2019 GMC Yukon

Direct-Fit Cooling Upgrade: Replaces failure-prone OEM plastic-tank radiators with a heavy-duty, all-aluminum 3-row unit engineered to withstand high thermal loads during heavy towing and extreme ambient temperatures.

The Stock Yukon Radiator Weakness

Factory K2XX platform radiators utilize thin single-row cores mated to composite plastic end tanks with crimped aluminum gaskets. Under repeated thermal cycling and prolonged towing stress, these plastic tanks develop micro-fractures, split along the tank-to-core seams, and suffer neck shear at the upper hose inlet. Furthermore, the limited stock core volume allows rapid heat soak in high ambient conditions, elevating both engine oil and transmission fluid temperatures.

The Engineering Solution

This drop-in performance radiator features a 3-row core constructed from high-grade AA5052 aluminum with 100% TIG-welded end tanks, completely eliminating failure-prone plastic and crimped seals. The expanded 1.73-inch core depth maximizes surface area and fluid volume for superior heat rejection. Dual integrated internal coolers maintain stable operating temperatures for both engine oil and transmission fluid under sustained load.
