Coolant Routing Upgrade Kit - 05-06 Mustang 4.6L

The Edelbrock Coolant Routing Upgrade Kit (Part No. 15804) is a precision thermostat relocation and radiator hose solution designed specifically for 2005–2006 Ford Mustang GT models equipped with the 4.6L V8 engine. This kit is essential for Mustang owners running the Edelbrock E-Force supercharger system who want reliable coolant circulation under sustained boost conditions.

This upgrade addresses thermal management challenges inherent to supercharged applications by repositioning the thermostat housing and providing hoses and clamps that integrate seamlessly with the E-Force supercharger system. By relocating the thermostat to a more optimal position within the cooling circuit, the kit improves coolant flow dynamics, allowing the radiator and water pump to operate more effectively under boost.

Proper thermal management directly impacts engine longevity, knock resistance, and tune stability, making this upgrade crucial for those logging track time or engaging in aggressive street driving. The kit includes all necessary hoses, stainless steel clamps, and hardware to ensure a factory-quality installation without modification to the engine block or radiator.
