Why is a triple-pass radiator better than a standard single-pass design?

A triple-pass design forces the coolant to travel through the core three times before exiting. This extended contact time with the cooling fins allows for maximum heat dissipation, resulting in lower coolant temperatures and more consistent engine cooling.

What makes CSF's B-Tube technology different?

CSF's B-Tube technology uses a unique shape for the cooling tubes that increases the surface area and improves heat transfer compared to traditional oval welded tubes. This means the radiator can absorb and dissipate heat more efficiently.

Does this radiator come with everything needed for installation?

This radiator is designed as a true plug-and-play 'drop-in fit' and includes CNC machined mounting pins and brackets. You will typically reuse your factory hoses and clamps for installation.

Product Details

If you're driving a 2014-2019 Ford Fiesta ST, you know that keeping temperatures in check, especially with the 1.6L EcoBoost engine, can be a challenge. The factory radiator, with its single-row aluminum core and plastic tanks, often struggles to keep up, even with just spirited driving or hot weather. This all-aluminum performance radiator from CSF is engineered to solve that problem, offering a massive improvement in heat absorption and dissipation.

CSF teamed up with experts in the EcoBoost platform to develop a radiator that can handle the demands of higher-powered engines, but it's a smart upgrade for any Fiesta ST owner. The core itself is a substantial 42mm thick and features two rows for increased surface area. CSF's exclusive B-Tube technology is used in the cooling tubes, which they claim increases heat transfer by about 15% over standard oval tubes. Combined with multi-louvered fins that maximize airflow, this radiator is built to dissipate heat effectively. A notable advantage is the triple-pass design; instead of coolant flowing through the core once, it's routed to flow through it three times. This maximizes heat dissipation, lowers outlet temperatures, reduces hot spots, and ensures more consistent cooling performance.

Constructed with 100% TIG-welded all-aluminum construction, this radiator is not only designed for superior cooling but also for increased strength and longevity compared to the stock unit. It's a true plug-and-play installation, meaning it fits right into your Fiesta ST without requiring any modifications. This CSF radiator is the ultimate cooling solution for any Fiesta ST owner looking to keep their engine running smoothly and reliably, especially when pushing the limits.
