Dayco Heater Hose Outlet

The Dayco Heater Hose Outlet line gives you replacement HVAC heater hoses and coolant hoses for the heater outlet position in your engine's cooling system. These hoses carry hot coolant from the engine to the heater core, so the cabin heater and defroster keep working. Dayco builds them as direct-fit, OE-style replacements, so each one matches the factory hose it replaces.

Key Features:

• EPDM rubber construction: The synthetic EPDM compound resists heat, ozone, weathering, and coolants.
• Reinforced for strength: Knitted reinforcement adds burst strength and helps the hose resist abrasion, oil, mud, salt, and road debris.
• Wide temperature range: Dayco cooling system hoses are designed to handle temperature swings from -40°F to +257°F (-40°C to +125°C).
• Coolant compatible: They are designed to work with common coolants and additives.
• Built to industry standards: Molded hoses in this line are built to SAE J20 and Class D-1 requirements. They also meet Type EC electrochemical requirements under SAE J1684, which helps guard against electrochemical degradation.
• Direct-fit design: Molded shapes and bends follow the original hose routing, so installation is straightforward.

Dayco has decades of experience in automotive belts and hoses. Replacing a worn, cracked, or leaking heater outlet hose helps maintain steady coolant flow, reliable cabin heat, and dependable engine cooling. Select the specific part number in this product group that matches your application.
