The Gates molded coolant hose for 2005–2010 Cadillac STS with the 4.6L V8 routes coolant between the radiator, throttle body and reservoir. This OE-style molded hose restores the proper coolant path and helps maintain stable engine temperatures. Its formed shape replaces original routing cleanly, making it a practical service part when the stock hose shows wear or leaks.
