2. Will the OEM C6 Corvette control module fit the DeWitts #32-SP463 and #32-SP463SC fan upgrade kit?
If you’re considering using one of our radiator fan combos, like #32-4139105A or #32-4139105B, with your C6 Corvette, rest assured that it is compatible with the factory fan controller. There’s an aluminum bracket included with our assembly where the OEM fan controller will be mounted. You won’t need to worry about buying a new control module, as this kit is designed to be compatible with your existing setup.
3. Are the DeWitts C6 radiator and fan combo kits plug and play?
While DeWitts C6 Corvette radiator fan combo and add-on fan kits are designed for ease of installation, it’s important to note that they are not completely plug-and-play. In particular, the stock wiring is hardwired into the original fan motor and has a multi-wire plug in the controller, so some modification is necessary.
To complete the installation, you will need to:
- Remove the stock fan controller from the original fan shroud
- Mount it to our new assembly
- Splice the red and black wires from the stock fan motor into the corresponding red and black wires on our fan kit
While this process isn’t plug-and-play, it is straightforward, and we provide detailed wiring instructions for your convenience. You can access our wiring guide here: C6 wiring instructions.
4. Which radiator is right for my C6 Corvette (model year specific)?
We offer different radiators for various 2005-2013 C6 Corvette models, and each one is tailored to the specific needs of your car. Below is a summary of recommended options:
5. Upgrading for modified C6 Corvettes:
Upgrading your C6 Corvette with the DeWitts 11” brushless fan kit offers a significant improvement in engine cooling efficiency and overall performance. This high-performance fan kit features a brushless motor that operates more quietly and efficiently than traditional fan systems, ensuring optimal airflow and reducing engine temperatures during even the most demanding driving conditions. Brushless technology also contributes to increased reliability and longevity, making it a smart investment for enthusiasts looking to extend the life of their engine and prevent overheating. Additionally, the DeWitts fan kit is designed for a seamless fit into your C6, ensuring easy installation and a perfect match with your vehicle’s cooling system. By upgrading to the DeWitts 11” brushless fan kit, you’ll enjoy improved cooling performance, enhanced reliability, and peace of mind knowing your Corvette can handle high-performance driving with ease.
C6 Corvette with ECS supercharger and headers: We recommend the #32-1139125A cut-down radiator and the #32-SP473SC dual brushless fan kit. You can also get it with a built-in oil cooler if necessary.
6. Can I add an oil cooler to my base model 2005-2013 Corvette that did not come with an oil cooler?
If you own a base C6 Corvette that did not come with an oil cooler, you can still add one to your radiator. DeWitts model #32-1139105M is designed for manual transmission base models, but if you want to add an internal engine oil cooler, the #32-1139105E is the option for you. It includes a 7-plate aluminum cooler in the driver-side tank. You’ll need an oil cooler line kit, such as DeWitts #32-894D, which includes the necessary fittings, lines, and adapter block.
7. Radiator and fan upgrades for supercharged C6 Corvettes:
For supercharged and heavily modified C6 Corvettes like those with the Vortech A&A kit, DeWitts cut-down radiators are the perfect solution. The #32-4139125B radiator fan combo will keep your supercharged engine running cool even in extreme conditions. The cut-down radiator provides extra clearance over the top of the radiator. The #32-4139125B model has a built-in engine oil cooler so you can remove the factory external oil cooler for added clearance. Added clearance is needed when installing the A&A intercooler, and this is the perfect solution to minimize extra parts.
8. What C6 Corvette radiator do I need with my wet sump or dry sump motor?
From 2005 to 2013, the Chevrolet Corvette C6 came with both wet sump and dry sump engine configurations, depending on the model. Here’s a breakdown:
