America’s Luxury Roadster Deserves the Best Aluminum Radiator Upgrade
With the radiator design GM used on the XLR Cadillac, like many designs on the road today, product costs and installation methods on the assembly line dictate the product and its compromises. An aluminum radiator core with injection molded plastic end tanks that are crimped to the core, sealed with a giant O-ring, means Cadillac befalls the same issues as most vehicles using a similar radiator design when asked to do more that it was designed for.
While this design saves weight and allows mounts to be molded into the tank, saving the cost of additional bracketry to secure the radiator, the vibration felt throughout the chassis from powerful engine upgrades and extended hard driving puts a lot of strain on these mounting points, creating cracks, and the harmonics/twisting motion creates leaks at the crimping point of the plastic end tanks. A lack of cooling system service creates failure points too. Solve these issues with a DeWitts Direct-Fit® performance aluminum Cadillac XLR and XLR-V radiator upgrade.
Built to Fit Your Cadillac XLR and XLR-V with Zero Modifications to Install
We get it, the injection molded end tanks save money and are easy to manufacture while handling the Cadillac’s stock cooling needs, but that’s not how we do things with DeWitts radiators. Our Pro Series Direct Fit® Cadillac XLR radiator is built using the highest quality aluminum materials, assembled, furnace brazed, and TIG welded all in our Wixom, Michigan facility (just 30 mins up I-96 from GM’s corporate headquarters at the Renaissance Center).
Each radiator carries a limited lifetime warranty, is pressure tested, and carefully double wall boxed with insulation to ensure it makes the trip to you and keeps your project moving forward.
Our press formed end tanks mean you won’t have any fitment issues and your factory cooling hoses, oil cooler lines, fan shroud, and more will all connect right up without modification. Flat plate welded end tanks that our competitors use rarely have this luxury, requiring modifications to your car to fit the larger tanks and/or additional bracketry or adapters to refit your stock components.
Using a two-row core built with 1-inch-wide core tubes and serpentine cooling fins maximizes air flow contact through the core to pull away the most heat, no matter the demand on the system, while increasing coolant capacity by one gallon over the stock single row core. Automatic transmission-equipped models feature a 7-plate internal cooler (twice the capacity of the stock cooler) while our engine oil cooler, also a 7-plate design, can be fitted optionally to radiator applications that weren’t originally fitted for one.
C6 Corvette Pro Series Direct Fit® Radiator Options
Our Cadillac XLR radiator replacement starts with our 32-1139105A DeWitts Radiator for base XLR models. Depending upon application needs we provide the correct end tank configurations for hassle free connection to factory coolers and mounting points. #32-1139105V has all the correct provisions for the driver side built in oil cooler and extra 1/2" hose port for all the factory connections.
Finally, be sure to add some DeWitts High Performance coolant to your order to protect your cooling system and help it achieve maximum thermal capabilities.
