Product Details

This TYC Radiator 2921 features a 17.24-inch core height, 34.02-inch core length, and 1.02-inch core thickness. The inlet measures 1.30 inches and the outlet measures 1.57 inches, both using hose clamp connections. The unit also includes a transmission oil cooler with quick-connect inlet and outlet ports, while engine oil cooling is not included. For fitment-sensitive applications, the notes specify w/o EOC and a 34-inch core width, so core width should be measured before ordering.

TYC Radiator is the product line designation for this radiator assembly, and it is built for direct replacement use in cooling-system service on GM full-size trucks and SUVs. This part cross-references Spectra Premium (e.g., CU2423) for the same application.

What This Radiator Helps Address

• Overheating caused by a leaking or restricted radiator
• Coolant loss from cracked tanks or damaged core passages
• Transmission temperature concerns when the cooler circuit is part of the radiator assembly
• Reduced cooling performance from clogged fins or internal flow restriction
• Fitment issues when replacing a 34-inch core-width radiator on select GM vehicles

Installation Notes and Tips

• Verify core width before ordering; this application calls for a 34-inch core width.
• Confirm whether the vehicle is equipped without an engine oil cooler, as noted in the fitment data.
• Match the inlet and outlet connection style to the original radiator before installation.
• Inspect hoses, clamps, and cooler lines for wear during radiator replacement.
• Bleed the cooling system thoroughly after installation to remove trapped air.

Quality Assurance

TYC Radiator 2921 is built as a replacement cooling component for the listed Chevrolet and GMC applications, with construction details and interchange references provided for fitment verification. Confirm vehicle configuration against the fitment notes before installation.
