Perma-Cool: Decades of Race-Proven Cooling Technology

Founded in 1969 and headquartered in Ontario, California, Perma-Cool grew out of a genuine passion for motorsports. The company's founder drew on firsthand racing experience — from off-road to drag racing — to identify a gap in the market: no one was offering truly complete cooling solutions engineered for performance. That garage-born mission evolved into one of the most respected names in automotive thermal management, serving everyone from weekend hot-rodders to Indy car builders.

What sets Perma-Cool apart is not just its heritage, but its commitment to American manufacturing. The brand operates a CAD/CAM engineering department, an in-house tool and die shop, and a CNC production line — all enabling tight quality control from design to finished product. Each component is extensively tested to exceed industry standards, which is why racers, hot rod enthusiasts, and gearheads have trusted Perma-Cool for over five decades.

A Comprehensive Cooling Product Line

Perma-Cool's catalog addresses virtually every thermal challenge under the hood. The brand is perhaps best known for its engine cooling fan assemblies — including the flagship Cool-Pack™ electric fan series and a full range of mechanical flex fans — engineered to maximize airflow whether you're crawling traffic or turning laps. These pre-assembled units are shipped ready to install and are reversible for pusher or puller configurations.

Beyond fans, Perma-Cool has built deep expertise in oil filtration and fluid management. Their engine oil filter housing mounts allow builders to relocate oil filters to more accessible positions in the engine bay, simplifying service and enabling remote oil cooling. Complementing these are the brand's engine oil filter adapter kits, which include sandwich-style and spin-on adapters that integrate seamlessly with oil cooler plumbing without sacrificing the stock filter location.

Perma-Cool also carries a line of fuel filter elements and complete fuel filters, including Fuel Filter/Water Separator systems designed to protect fuel systems from contaminants and moisture — a critical consideration for high-performance and off-road applications alike.

Built for the Track, Proven on the Street

Whether you're building a show car, upgrading a daily driver, or prepping a dedicated race vehicle, Perma-Cool offers the thermal management components to keep your engine, transmission, and fuel system operating safely within their ideal temperature ranges. The breadth of the product line — from individual filter elements to complete dual-circuit cooling systems — means most builds can be outfitted with a cohesive Perma-Cool solution from a single trusted manufacturer.
