CSF: Over Seven Decades of Cooling Excellence

Few names in the automotive cooling world carry as much history as CSF. Founded in 1947 in Bombay (now Mumbai), India, the company began as a small family-run shop offering tire changes and basic repairs. Spotting a trend toward poor-quality radiators in the market, founder Jadev Dolwani pivoted into parts manufacturing — a decision that would set the stage for a global cooling empire. By 1973, a state-of-the-art factory in Singapore allowed CSF to branch well beyond radiators into the full world of cooling, and by the late 1970s the brand had crossed the ocean to establish a North American presence.

That North American expansion proved prescient. As import automobiles surged in popularity throughout the early 1980s, CSF — already experienced with foreign makes and models — was uniquely positioned to meet demand. Today, the company is headquartered in Rancho Cucamonga, California, and remains a privately held, fourth-generation family business with manufacturing facilities on multiple continents, coast-to-coast U.S. distribution, and warehousing capacity for over one million units.

Engineering Built In-House

What separates CSF from commodity cooling suppliers is the depth of its in-house manufacturing. CSF engineers design products from scratch, producing detailed blueprints before a single part is made. Their facilities include proprietary six-stage tube mills for all-aluminum B-tube cores, automated core-building machines designed in-house, six-axis CNC machines for precision brackets and mounting hardware, an aluminum-brazing oven with digital temperature monitoring, and a wind tunnel used for airflow testing and salt-spray durability validation. This level of vertical integration gives CSF an engineering edge that is difficult to replicate — and it shows in the quality and fitment of every product they produce.

A Complete Cooling Lineup for Street and Track

CSF's catalog spans both the everyday driver and the committed enthusiast. Their radiators — the backbone of the brand — cover thousands of OEM replacement and high-performance applications, from daily drivers like the Toyota Tacoma and Ford Transit to high-strung machines like the Dodge Durango Hellcat and hybrid platforms including the Toyota Prius and Corolla Cross. For forced-induction builds, CSF intercoolers are engineered using the same B-tube and multi-louvered fin technology found in their top-tier racing products, making them a favorite for turbocharged BMW, Toyota Supra, and Volkswagen MQB builds. Keeping the cabin comfortable is handled by CSF's lineup of A/C condensers, which are built to OEM specifications for reliable, drop-in fitment across a wide range of makes and models.

For those seeking comprehensive solutions, CSF offers radiator and A/C condenser assemblies that simplify installation by combining both components into a single unit. And for performance-oriented applications where engine longevity under stress matters most, CSF engine oil coolers — including their well-known universal-style "BOSS" cooler series — provide heavy-duty bar/plate construction capable of handling engine oil, transmission fluid, power steering fluid, and more.

Trusted from the Street to the Race Track

CSF's reputation extends well beyond replacement parts. Their Racing & High Performance division supplies cooling solutions to professional motorsport teams and performance enthusiasts worldwide, with products proven in some of the most demanding racing environments on the planet. Whether you are restoring a classic, daily driving a modern import, or building a track car, CSF offers a cooling solution engineered with decades of real-world expertise behind it.
