Billet Pro Shop Coyote Billet Thermostat Housing -20 ORB (EN058)
Upgrade your Ford Coyote cooling system with the Billet Pro Shop Billet Thermostat Housing (EN058). CNC machined from 6061-T6 billet aluminum, this housing replaces bulky factory coolant connections with -20 ORB ports on both ends, allowing the use of AN-style fittings and hoses for a cleaner, more versatile cooling system setup.
Designed for high-performance and racing applications, the EN058 simplifies coolant hose routing around turbocharger systems and other engine modifications while maintaining a large coolant flow area. Unlike specialized racing thermostat housings, it retains compatibility with an OE-style thermostat for convenient servicing and replacement.
-20 ORB Cooling System Conversion
The factory Coyote cooling system uses bulky plumbing and connections that can complicate hose routing in modified engine bays. The EN058 provides -20 ORB connections on both ends, allowing custom AN-style coolant hoses to be routed between the engine and radiator.
This configuration is particularly useful for turbocharged and high-horsepower Coyote applications where additional clearance, secure plumbing connections, and flexible hose routing are important.
Billet Aluminum Construction
Manufactured from CNC machined 6061-T6 billet aluminum, the housing features a black anodized finish for durability and a clean appearance. It accepts an OE-style thermostat, allowing replacement with commonly available service parts rather than requiring a specialized thermostat.
