 If you go into your local auto parts store and order this radiator, they will likely offer you a plastic tank / aluminum core radiator of inferior quality that will not fit perfectly or look anything like an original and isn’t even made in the USA. We are aware that parts-store radiators are much less expensive than ours. But they do not fit as well, nor look correct like ours do. They also won't cool your valuable engine nearly as well!

 This GM replacement radiator has a 28¼" core width between the tanks, and is 18½" tall including side channels. It has three rows of ½" tubes and an 8½" transmission cooler with 5/16" inverted flare fittings in the outlet tank. The upper hose neck has an outside diameter of 1½". The lower neck is 1½" O.D. If your radiator requires a ¾" Heater Return Line below the filler neck use CR 03620.

Before ordering this radiator please confirm that the radiator you need has a 28¼" core width. Both tanks are 2¾" thick. It is an exact fit for many 2-row and 3-row GM applications. 

This radiator can be custom made in multiple versions to suit your specific needs. The part number listed here is a standard 3-row core with an AUTOMATIC transmission cooler built into the passenger side tank. It can be built WITHOUT the transmission cooler for MANUAL transmission applications.

It can also be built with a high efficiency style core that provides about 20% better cooling without increasing the core thickness or decreasing the fan clearance. By placing the tubes on closer centers to each other, more surface area is built into the core (without sacrificing airflow) for better heat transfer.

CR 03610 AR – Automatic transmission with standard cooling
CR 03610 AH – Automatic with high efficiency cooling
CR 03610 MR – Manual transmission with standard cooling
CR 03610 MH – Manual transmission with high efficiency cooling

Note: Models built after 1979 had a 1¼” inlet neck (where the top hose connects on the driver’s side).
This radiator has the drain plug on the drivers side near the steering box.

If you want to confirm that this is the correct application for your vehicle, please contact us via phone or e-mail. It does not have a heater return neck as do most generic replacement radiators.
