TYC Radiator for Toyota Tundra

The TYC Radiator 2321 is a direct-fit cooling replacement for 2000-2006 Toyota Tundra applications. Built with an aluminum core and a downflow design, it includes a concentric transmission oil cooler to support engine cooling and automatic transmission fluid temperature control in one unit.

Key Features

  • Aluminum core construction for efficient heat transfer
  • Downflow radiator design
  • Transmission oil cooler included with concentric oil cooler type
  • Hose clamp inlet and outlet connections
  • 1.50 in. inlet and outlet diameters
  • Single-row core design with 27.37 in. core height, 22.64 in. core length, and 1.42 in. core thickness
  • Fits Toyota Tundra models from 2000 through 2006

Product Details

TYC 2321 is engineered for Toyota Tundra cooling system service where radiator replacement is needed and transmission fluid routing is part of the original setup. The aluminum core, 83 total tubes, and 84 total fin rows support heat dissipation, while the concentric transmission oil cooler integrates the fluid-cooling function into the radiator assembly. This part cross-references Spectra Premium CU2321 for the same application.

Common Repair Applications

  • Radiator leakage or coolant loss
  • Overheating during stop-and-go or towing use
  • Transmission fluid temperature concerns tied to the radiator cooler circuit
  • Corrosion or damage to the original Toyota Tundra radiator
  • Restricted cooling performance from an aging core

Installation Notes

Verify hose connection size, cooler line routing, and core dimensions before installation. This radiator uses hose clamp inlet and outlet connections with 1.50 in. ports, and the transmission cooler uses tube fitting connections. Confirm the vehicle’s cooling system is drained, flushed, and refilled with the correct coolant after replacement. Fits 2000-2006 Toyota Tundra, N/A.

Quality Assurance

TYC Radiator components are built to match the listed application and specifications for service replacement use. Confirm part number 2321 against the original radiator and cooler layout before installation to ensure proper fitment on your Toyota Tundra.
