Gates HVAC Heater Hose P/N:HHA139
Keep coolant moving through the heater circuit with the Gates heater hose HHA153, an OE Exact coolant tube that installs as a direct-fit replacement on the 2003-2006 Mercedes-Benz E500, 2004-2005 Mercedes-Benz E320, and 2006 Mercedes-Benz CLS500. It carries engine coolant between the cooling system and the heater core so warm coolant reaches the core for cabin heat and defrost.
Also cataloged as a Gates hvac heater hose, this coolant tube is a wear item — over time coolant heat and pressure can lead to cracks, hardening, or leaks. If a failed hose or tube is the source of coolant loss or a shortage of cabin heat, this replaces it. Check the Buyer's Guide tab for the engine-level fitment on your vehicle.
