 This is a Custom-Built radiator! Although it shows “zero” in stock, we do keep the parts needed to build this radiator on hand, so please call us to place your order and we will build the radiator within 1-5 business days. Call for a more accurate time estimate. Please see below for customization information.

 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 was the original GM crossflow design. Therefore it has two different size tanks. The inlet header is 2¾" (as most were until the 1980s), but the outlet tank was 3½". Also, the transmission oil cooler, located in the outlet tank  (on models with an automatic) is 12", which is 4" longer than subsequent models. It also has 3/8" inverted flare fittings. The upper hose neck has an outside diameter of 1½". The lower neck is 1¾" O.D. If your radiator has a ¾" heater return hose in the center of the outlet tank (passenger side), use CR 03050 AR.

 Before ordering this radiator, please confirm that the radiator you need has a core width of 28¼" between the tanks and a 1½” diameter top hose connection. This radiator has three rows of ½" tubes on 9/16" centers. This radiator has a 1¾" diameter lower neck.  Applications for this radiator include:

1965-1970 Buick
Estate Wagon

1968-1971 Chev
Monte Carlo (70-71)

1965-1971 Oldsmobile
Delata 88, Delmont 88

1967-1971 Pontiac
Grand Prix

If you do need a radiator with a ¾" heater return hose connection on the passenger side please order # CR 03050

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 03020 AR – Automatic transmission with standard cooling
CR 03020 AH – Automatic with high efficiency cooling
CR 03020 MR – Manual transmission with standard cooling
CR 03020 MH – Manual transmission with high efficiency cooling

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.
