Product Details

TYC Radiator 2370 is built for vehicles that rely on integrated cooling for the engine, transmission, and engine oil circuits. The radiator uses a single-row, crossflow design with aluminum core material and plate oil cooler sections to help manage heat in full-size SUVs and heavy-duty pickups. This part cross-references Spectra Premium CU2370 and APDI 8012370 for the same application. Compatible fitment includes Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Silverado 1500, Silverado 2500 HD, Silverado 3500 HD, Suburban 1500, Avalanche, and GMC Yukon, Sierra 1500, Sierra 2500 HD, Sierra 3500 HD, and Yukon XL models across the listed years. The TYC 2370 radiator is also listed for Hummer H2 applications with the specified cooling package notes.

What This Radiator Helps Address

• Overheating caused by a worn or restricted radiator core
• Transmission temperature issues tied to a failing transmission oil cooler
• Engine oil cooling loss from damaged integrated cooler passages
• Coolant leaks from aging aluminum radiator tanks or core seams
• Reduced cooling efficiency in towing, hauling, or stop-and-go driving

Installation Notes and Tips

Verify core size, cooler style, and connection type before installation. This radiator is listed for specific GM truck and SUV configurations, including applications with heavy-duty cooling, 4.10 axle ratio, front-mounted fitment notes, and EOC/TOC requirements. Confirm hose clamp inlet and outlet sizing, and match the vehicle’s oil cooler port style to the quick-connect and QC fittings supplied on the unit. Use the fitment notes to confirm the exact year, model, and cooling package before ordering.

Quality Assurance

TYC Radiator 2370 is engineered as an OE-style replacement radiator for listed Cadillac, Chevrolet, and GMC applications. Its aluminum construction, integrated oil cooler design, and application-specific dimensions support consistent replacement fitment for the vehicles shown.
