The PSC 16" Heat Sink Super Flow Cooler is a compact, high efficiency solution for managing power steering temperatures in demanding off-road and race environments. This design delivers exceptional heat transfer with minimal airflow, making it ideal for applications where traditional air to oil coolers may not receive consistent direct airflow. The 3" diameter extruded aluminum core features both internal and external heat dissipating fins to maximize cooling efficiency. This design allows the cooler to shed heat effectively without relying solely on vehicle speed or fan driven airflow. Its compact size allows for flexible mounting options in tight chassis layouts. Includes: (1) 16" Heat Sink Super Flow Cooler Core Specifications Length: 16" Core Diameter: 3" Construction: Extruded Aluminum Internal Cooling Fins: Yes External Cooling Fins: Yes End Construction: Welded Aluminum Ends Cooling Style: Heat Sink / Passive Airflow Assisted Fitment Universal fitment for hydraulic power steering systems in: Rock crawlers & bouncers Ultra4 and endurance race cars Custom buggies High-performance trail rigs Mounting Notes: Cooler should always be mounted below the power steering pump Do not mount inside the engine compartment Recommended mounting locations include: In front of the radiator Directly below the radiator Under the floorboards Along frame rails Tech Insight Unlike traditional tube-and-fin coolers that rely heavily on direct airflow, PSC’s heat sink design uses both internal and external fins to increase surface area and maximize heat dissipation. This allows the cooler to perform efficiently even in low speed crawling conditions where airflow is limited. The rugged extruded aluminum body with welded ends ensures long service life, even in harsh off-road environments with vibration, debris, and extreme temperatures.
