CSF 13-18 Ford Focus ST Radiator

Built with a dual-core design, this CSF radiator for the 2013-2018 Ford Focus ST is designed to handle the extra heat generated by its turbocharged engine. The dual-core construction means there are two separate passages for coolant to flow through, increasing the surface area for heat dissipation compared to a single-core radiator. This is crucial for keeping your engine temperatures in check, especially during spirited driving or track use where the stock cooling system can be overwhelmed.

CSF uses a high-efficiency, multi-louvred fin design on this radiator. These fins are precisely shaped to direct airflow through the core, maximizing the amount of heat that can be transferred from the coolant to the surrounding air. The tanks are constructed from durable aluminum, and the entire unit is TIG-welded for strong, leak-free connections. This well-built radiator is a direct fit, meaning it's designed to bolt into the factory mounting locations without needing any modifications, making installation straightforward.

When you're pushing your Focus ST hard, maintaining optimal engine temperature is key to performance and longevity. This CSF radiator is a solid option for drivers who demand more from their cooling system than the factory unit can provide. It's a significant upgrade that helps prevent heat soak and ensures your engine stays cool when it matters most.
