The Gates molded heater hose for 1999–2004 Nissan Frontier V‑6 3.3L connects the intake manifold to the pipe assembly in the cooling and heater plumbing. As a molded replacement, it preserves the factory routing and connections, ensuring the coolant passage between those parts functions as intended to support engine and heater system operation.
