Radiator Cadillac CTS-V 04-07 Gen 1 Raw

The DEWITTS Radiator for Cadillac CTS-V 04-07 Gen 1 is a direct-fit aluminum cooling solution engineered specifically for the LS-based performance platform. Built from durable aluminum construction, this single-pass radiator delivers efficient heat dissipation for the high-output V8 engine that defines the first-generation CTS-V, with a 26.6-inch width and 21.5-inch height optimized to fit factory mounting locations without modification.

Key specifications include passenger-side inlet and driver-side outlet configuration, compatible with manual transmission models from 2004 through 2007. The 2.25-inch core depth accommodates the aggressive cooling demands of the 550-horsepower V8 while maintaining a compact footprint. Aluminum cores offer superior thermal transfer compared to older copper designs, critical for sustained track performance and street driving in warm climates where factory cooling systems approach their thermal limits.

This radiator addresses a known pain point for CTS-V owners: OEM cooling systems can struggle during extended high-performance driving, spirited track sessions, or in regions with high ambient temperatures. The DEWITTS design provides additional cooling capacity without requiring custom fabrication, hose rerouting, or modifications to engine bay layout. Direct-fit installation means no adapter fittings, no guesswork about inlet/outlet orientation—bolt in and run. Owners upgrading to performance headers, superchargers, or tuning packages particularly benefit from the increased thermal margin this radiator provides.

DEWITTS radiators are purpose-built for serious enthusiasts rather than casual maintenance replacements, engineered with the thermal engineering that LS platform owners have relied on for high-output street and competition applications. The 17.93-pound unit is ready to ship and install—no core charge, no surprises.
