The Gates molded heater hose connects the heater to the engine on 1998–2004 Nissan Frontier trucks with the 2.4L 4‑cylinder, restoring proper heater-circuit routing. Its formed contour fits the specific heater-to-engine path for that application, offering an application-specific replacement intended to maintain correct coolant flow between the heater and engine connection for the listed Frontier model years.
