Dayco® Small I.D. Molded Heater Hose is designed to replace OEM coolant hose in applications where molded hose in small diameters (1" I.D. or smaller) is required.
Features & Benefits:
The molded configuration eliminates the need for multiple connections of hoses and clamps.
The knitted reinforcement and synthetic EPDM construction provides high strength and resistance to detrimental environmental elements, coolants, and temperature variations of -40°F (-40°C) to +257°F (+125°C).
If the OE parts have a "quick connect" end, the Dayco® Small I.D. Molded Heater Hoses are also made with the quick connect assembled onto the hose for fast, convenient installation.
Meets SAE J20R4 EC, Class D-1 requirements
