URO 8D0819371H Heater Core Supply Hose

The URO 8D0819371H is a direct-fit replacement heater core supply hose, also commonly referred to as a coolant heater hose. This hose serves as the feed line, routing hot engine coolant from the cylinder head flange to the heater core to deliver cabin heat.

Rubber coolant hoses are subjected to constant thermal cycling and chemical exposure, making them a wear item that should be inspected regularly. Common signs of a failing heater hose include visible cracking, bulging, splitting at connection points, and loss of flexibility. Replacing a worn hose promptly helps maintain cooling system integrity and prevent coolant loss.
