Dayco Super Duty Heater Hose Outlet

Dayco Super Duty Heater Hose Outlet molded heater hoses are direct-fit replacements for the heater outlet coolant hose. They replace cracked, spongy, swollen or leaking hoses and help restore reliable cabin heat and coolant flow. Dayco builds each hose to match the original equipment shape, so it routes and connects like the factory hose.

Key Features:

• EPDM rubber construction: Synthetic EPDM rubber resists oil, mud, salt, road debris, ozone and coolants.
• Knitted reinforcement: The inner base is reinforced with knitted rayon for strength and burst resistance.
• Wide temperature range: Handles temperatures from -40°F to +257°F (-40°C to +125°C).
• Industry standards: Meets SAE J20R4 Class D-1 requirements and Type EC electro-chemical requirements per SAE J1684. This helps prevent inner deterioration caused by static electric charge build-up.
• Molded OE-style design: The direct-fit shape resists premature stress cracking and keeps installation straightforward.

Check cooling system hoses regularly and replace them at the first signs of wear. A new Dayco heater outlet hose helps protect the engine from coolant loss and overheating, and it keeps the heating system working.
