Dayco Heater Hose

Dayco Heater Hose is a line of EPDM rubber coolant hoses that carry hot engine coolant between the engine and the heater core. They are also sold as heater hoses or HVAC coolant hoses. They help the cabin heating system deliver steady, reliable warmth.

Key Features:

• EPDM rubber construction resists heat, ozone, weathering, and coolant exposure
• Reinforced build helps the hose hold up under pressure and temperature cycling
• Molded and curved designs help the hose route cleanly and resist kinking in tight engine bay spaces
• Made to meet OE-style fit and performance requirements for dependable service
• Inlet, outlet, and heater-to-manifold hose styles are available within the line

Dayco is a long-established name in belts, hoses, and engine components. Replacing an aging heater hose helps prevent coolant leaks, overheating, and loss of cabin heat.
