What This Radiator Helps Address

• Coolant leaks from a damaged or corroded radiator

• Transmission cooling concerns on vehicles with TOC provisions
• Engine oil cooling system replacement needs on vehicles with EOC provisions
• Fitment issues when replacing an original radiator with the same core dimensions

Installation Notes and Tips

Verify the existing radiator core size and cooler configuration before ordering. This OR2370 application requires the 34 in. x 17-1/2 in. x 1 in. core specification on most listed vehicles, while some 2011-2012 Cadillac Escalade applications use a 34 in. between-tanks configuration. Confirm that your vehicle matches the listed year, make, model, and cooler equipment before installation.

For best results, inspect hoses, clamps, and related cooling-system components during radiator replacement. Flush the cooling system if contamination or debris is present, and refill with the correct coolant specification for the vehicle.
