Description

Heater Hose – Inlet carries engine coolant into the cabin heating circuit, feeding the heater matrix that warms air inside the HVAC housing.

On the 300 TDi 2.5L 4-cylinder turbo diesel, this is the inlet leg of the heater circuit, delivering hot coolant from the engine cooling system to the matrix; the cooled return is handled by the companion outlet hose. Moulded to suit the original routing and connection points.
