The Gates molded heater hose for 1999–2001 Volkswagen Jetta 2.0L 4-cylinder connects the heater to the throttle body as a purpose-built molded hose. It's supplied to match the specific heater-to-throttle-body routing on that Jetta, enabling correct coolant flow for the heater circuit and serving as a replacement for the original molded connection.
