CU2370 Replacement Radiator for Silverado Tahoe Suburban - Durable Fit

In this review of the CU2370 replacement radiator the bottom line is simple: this unit is for owners of late 1999 through 2014 GM full-size trucks and SUVs who need a direct-fit, durable replacement. The reviewer found the radiator delivered a reliable match to OE mounting points and hose locations, and its aluminum core with plastic tanks offered improved thermal conductivity without any signs of leakage after bench testing. If you want a like-for-like swap that installs easily and ships with protective packaging, this radiator is worth considering.

Key Features

• Vehicle Compatibility: Covers a wide range of GM models and engine sizes so buyers can find the CU2370 to replace many Silverado, Sierra, Tahoe, Yukon and Suburban radiators.
• Aluminum Core: The high-grade aluminum core improves heat transfer to help the engine maintain stable temperatures under load.
• Plastic Water Tanks: Corrosion-resistant tanks reduce long-term deterioration compared with older mixed-material units.
• Shockproof Packaging: Foam secured in four corners prevents deformation and transport damage for safer delivery to the garage.
• OE Fitment: Inlet, outlet and mounting screw specifications mirror the original equipment for straightforward installation.
• Leak-Tested: Each radiator is tested for leaks to ensure service life and reduce the chance of early failure.

Who It's For

This radiator is aimed at owners of 2005-2012 Silverado 1500, 2001-2014 Tahoe, 2000-2014 Suburban 1500 and related GM trucks and SUVs who need a replacement that matches original dimensions and fittings. It works well for DIY mechanics and independent shops that prefer a direct-replacement part with plug-and-play ports and mounts.

Shoppers who need a custom performance cooling solution, a different core thickness, or exact OEM branding should look elsewhere, since this offering is positioned as a functional, OE-compatible replacement rather than a high-performance upgrade.
