Dayco Auxiliary Heater Hose

Dayco Auxiliary Heater Hose is a molded and flexible coolant hose line for vehicle heating and auxiliary heater circuits. It carries hot engine coolant between the engine, heater core, and auxiliary heating components. Use it to replace worn, cracked, soft, or leaking heater hoses and restore reliable cabin heat and defrost performance.

Key Features:

• Built to carry engine coolant (antifreeze) in heater and auxiliary heater plumbing
• Made with synthetic rubber designed to resist heat, ozone, and coolant exposure
• Reinforced construction helps the hose hold its shape and resist collapse and kinking under pressure and vibration
• Flexible design makes routing and installation easier
• Designed to meet or exceed original equipment performance expectations

Dayco is a long-established name in belts, hoses, and engine components. Replacing aged heater hoses with a quality Dayco hose helps prevent coolant loss, overheating, and heating system problems. Choose the part number that matches your application from the available options.
