The Gates molded upper coolant hose for 1999–2004 Nissan Frontier 3.3L V6 replaces the upper molded connection in the cooling circuit. It returns coolant flow from the engine toward the radiator and associated plumbing, providing a practical replacement when the factory hose ages, leaks, or is removed during routine cooling system service.
