Engineered specifically for LS series engines, this molded hose set streamlines coolant piping layout for a cleaner, more efficient installation.
Replaces OEM part #551065 and includes two hoses: one 5/8-inch ID and one 3/4-inch ID, each 24 inches long with a integrated 4-inch 90-degree bend.
Efficiently circulates high-temperature coolant from the pump to the heater core or radiator, supporting both engine cooling and cabin heating operations.
The precision 90-degree elbow design minimizes flow restriction, improves heat dissipation, and fits seamlessly into complex engine bay plumbing.
Designed for straightforward replacement with standardized dual-size inner diameters and lengths—simply match the hose size and length to your original parts for a perfect fit.
