The Gates molded heater hose is the heater inlet hose for 1999–2004 Jeep Grand Cherokee models with the 4.0L inline‑6, providing the correct routed connection at the heater inlet. Its formed design matches the heater-inlet path for that engine and model range, offering an application-specific replacement to maintain proper coolant flow into the heater core on the listed Grand Cherokee years.
