This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

  • Overheating caused by restricted coolant flow
  • Transmission fluid temperature issues tied to a failed internal cooler
  • Corrosion or deterioration in the original radiator assembly
  • Reduced cooling performance in a high-mileage Toyota Avalon

Installation Notes and Tips

Verify inlet and outlet hose sizes, transmission cooler connections, and overall core dimensions before installation. Flush the cooling system and inspect hoses, clamps, and the radiator cap during replacement. Confirm that the transmission cooler lines are clean and properly seated to prevent leaks after installation.
