Description

The HPS 57-1903-BLUE radiator hose from Stillen is engineered as a superior replacement for OEM rubber radiator hoses, which are prone to weakening and failure over time. This high-performance silicone hose kit is specifically application-engineered for a perfect fit on the 1999-2004 Ford Mustang equipped with the 3.8L V6 engine. It replaces OEM part numbers 1R3Z-8260-AA and F7ZZ-8286-CA, ensuring seamless integration. The hose features a maximum temperature rating of 350°F (177°C), providing robust performance when you need it most. Installation is facilitated by the inclusion of 100% stainless steel, industrial-grade embossed hose clamps.
