CSF 16-18 Ford Focus RS Radiator

When you're pushing your 2016-2018 Ford Focus RS hard, especially with performance upgrades or in warmer climates, keeping coolant temperatures in check becomes critical. The factory radiator, while adequate for stock setups, can struggle under demanding conditions. This CSF all-aluminum radiator is built to handle that extra heat, offering a significant improvement over the original unit. It's designed to be a direct replacement, meaning it fits right into your existing cooling system without needing any modifications.

What you're getting here is a well-built, 100% all-aluminum radiator featuring a substantial 42mm, 2-row core. This thicker core, combined with CSF's B-Tube Technology, increases the surface area for heat transfer by about 15% compared to standard oval tubes. The multi-louvered fins are also designed to maximize airflow, helping to dissipate heat more effectively. A key feature is the triple-pass internal design, which forces coolant to flow through the core three times before exiting. This routing ensures more even heat distribution, reduces hot spots, and ultimately leads to lower outlet temperatures, which is crucial for engine longevity and consistent performance.

This radiator is TIG-welded for increased strength and durability, ensuring it can withstand the rigors of performance driving. It includes CNC machined mounting pins and brackets for a true plug-and-play installation. Each unit is individually leak and pressure tested before it leaves the factory, and it comes with a 2-year limited warranty, giving you confidence in its reliability.
