Radiator for Cadillac Escalade (2002-2008) 5.3L 6.0L 6.2L

All-Aluminum 3-Row Crossflow Radiator for 2002-2008 Cadillac Escalade (GMT800 / GMT900)

What it Does: The 3-row aluminum radiator replaces failure-prone factory cooling units on the 2002-2008 Cadillac Escalade to maximize thermal dissipation, stabilize transmission and engine oil temperatures, and eliminate chronic end-tank leakage under severe towing conditions.

The Stock Cadillac Escalade Cooling Weakness

Factory OEM radiators installed in the GMT800 and GMT900 platform rely on crimped plastic nylon end tanks mated to an aluminum core via an elastomeric gasket. Over time, thermal cycling from Vortec 5.3L (LM7), 6.0L (LQ9), and 6.2L (L92) powerplants degrades the plastic, causing micro-fractures along the stress points of the inlet and outlet necks. Under heavy load or elevated ambient temperatures, the factory single-row core suffers heat soak, while the crimped seams blow out under pressure spikes, causing rapid coolant loss and catastrophic overheating risks for the transmission and valvetrain.

The Engineering Solution

This 3-row crossflow configuration is engineered with 100% TIG-welded aircraft-grade aluminum, completely eliminating failure-prone plastic tanks and crimp seals. Featuring a 34-inch wide high-density fin-and-tube core, it increases fluid capacity and air-contact surface area over standard factory units. The radiator integrates both a passenger-side auxiliary transmission fluid heat exchanger and a driver-side engine oil cooler, maintaining critical fluid viscosity during heavy-duty towing. Billet-machined hose connections guarantee leak-proof integrity under elevated cooling circuit pressures.

Frequently Asked Questions & Fitment Warnings

Does this fit the GMT800 and GMT900 Escalade?

Yes, this is a direct fit for the 2002-2008 Cadillac Escalade equipped with the 5.3L LM7, 6.0L LQ9, and 6.2L L92 engines. This unit does not fit models equipped with the smaller 28-inch core radiator; verify your core width measures 34 inches between the end tanks prior to ordering.

Are transmission and oil cooler fittings pre-plumbed?

Yes, internal cooler lines are integrated on both sides (engine oil cooler on driver side, transmission cooler on passenger side) matching factory thread geometry for direct line attachment.

The Cadillac Towing Caliber

Built to handle the immense thermal strain of high-displacement GM small blocks under prolonged load, this all-aluminum core ensures maximum towing reliability, keeping transmission fluid and coolant rock-steady on steep highway grades.
