Dayco Molded HVAC Heater Hose

The Dayco Molded HVAC Heater Hose is a pre-formed coolant hose for the heating system. It carries hot engine coolant between the engine and the heater core. Molded heater hoses are also called heater hoses, coolant hoses, or HVAC hoses. Each one is shaped to match the original routing, so it installs without kinking.

Key Features:

• Molded, pre-formed shape that follows the original hose routing for a clean installation
• Reinforced construction that resists the pressure and heat of an engine cooling system
• Synthetic rubber compound that resists coolant, heat, ozone, and weathering
• Smooth inner tube that supports consistent coolant flow to the heater core
• Built to meet or exceed OE performance requirements

A worn heater hose can crack, swell, or leak, which can cause coolant loss, weak cabin heat, or overheating. Replacing it with a Dayco molded hose helps restore reliable heater performance and cooling system integrity. Dayco is a long-established manufacturer of belts, hoses, and engine components for the automotive aftermarket.
