Product Details

The ACDelco 16447M Professional Molded Branched Heater Hose is a premium aftermarket replacement hose designed to transport coolant from the engine to the heater core, providing efficient cabin heating. This factory-molded hose is engineered to fit today's tighter engine compartments with precision GM OE-style construction.

Key Features:

  • EPDM Rubber Construction: Manufactured from a proprietary blend of EPDM (ethylene propylene diene monomer) synthetic rubber for superior flexibility, extended service life, and enhanced resistance to electrochemical degradation (ECD), the leading cause of heater hose failure
  • Wide Temperature Range: Temperature rated from -40°F to 275°F (-40°C to 135°C) for reliable performance in extreme conditions
  • Multi-Application Versatility: Approved for coolant, water, and air applications, as well as marine use
  • GM OE-Style Molding: Pre-formed to Original Equipment specifications for precise fitment and easy installation
  • Branched Design: Features multiple connection points to serve complex cooling system configurations

ACDelco Professional parts are manufactured to meet rigorous standards for fit, form, and function, making them an excellent choice for General Motors vehicles and other makes and models. This heater hose provides the performance and dependability expected from ACDelco's premium aftermarket product line.

Note: Not suitable for fuel or oil transfer applications.
