CSF 09-13 Cadillac CTS-V Radiator

CSF has been making radiators for over 50 years, so they know a thing or two about keeping engines cool. If you've got a 2009-2015 Cadillac CTS-V, especially one that sees track time or has a high-horsepower build, you know how important it is to have a radiator that can keep up. This CSF High-Performance All-Aluminum Radiator is built to handle those demands.

What makes this radiator stand out is CSF's B-Tube Technology. Instead of a standard oval tube, they use a specially shaped 'B' tube. This design is actually stronger, allowing them to use thinner, lighter aluminum while still getting better cooling efficiency. The B-tube design increases the heat transfer surface area by about 15% compared to regular tubes, giving you the cooling power of two smaller tubes in the same space. Plus, they use ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow and heat rejection, all tested in their wind-tunnel lab.

This radiator is designed as a true drop-in fit, meaning you won't need to modify anything on your CTS-V to install it. It accepts all the original mounting brackets, the AC condenser, and even the quick-connect hoses, so you can reuse your factory or aftermarket hoses. The brackets and connections are CNC machined for a precise fit and solid durability, ensuring everything attaches just like the original.
