Heat Exchanger GT500 w/ Fans

The AFCO Racing Products Heat Exchanger GT500 w/ Fans is purpose-built for high-performance Ford Modular engines in marine and boating applications where reliable thermal management is non-negotiable. Whether you're pushing a twin-cooled inboard or optimizing an aftermarket Mustang powerplant in a center console, this dual-fan aluminum heat exchanger maintains consistent coolant temperatures even under sustained full-throttle conditions. Boaters and performance enthusiasts who demand dependable cooling without sacrificing engine bay space will appreciate the compact yet efficient design that fits OEM and custom installations alike.

Built from lightweight aluminum construction with integrated dual-fan configuration, the Heat Exchanger GT500 maximizes heat dissipation across a large-surface-core design optimized for Ford Modular platforms. The included electric fans activate based on coolant temperature, reducing parasitic load during cruising and ramping up automatically when demand peaks—critical for maintaining safe operating temperatures during extended full-throttle runs or idle periods in shallow water. At 20.55 lbs and measuring 15.5 x 7.25 x 37 inches, the unit offers robust cooling capacity in a footprint that suits both tight marine engine bays and dedicated performance builds without requiring extensive modification.

This exchanger is engineered for 2007–2012 Ford Mustang owners stepping up to modified power levels, as well as marine builders integrating Ford crate motors into custom applications. Installation pairs straightforward inlet and outlet hose connections to existing cooling circuits, and the natural aluminum finish resists corrosion in saltwater environments when properly maintained. Boaters running hard in hot climates or year-round operators will see measurable improvements in engine reliability, reduced risk of vapor lock, and extended engine lifespan when paired with appropriate coolant and regular maintenance schedules.
