Lower Radiator Or Coolant Hose by DAYCO - 80319

Dayco lower radiator hose is designed with knitted reinforcement and all EPDM construction for increased strength and resistance to oil, mud, salt, road debris, ozone, coolants, and temperature variations of -40˚F (-40˚C) to +257˚F (+125˚C) that are required for OEM radiator hose replacements. Dayco radiator hose has an inner base tube that is reinforced with knitted rayon for maximum strength and burst resistance for longer life. Besides meeting SAE J20R4, Class D-1 requirements, radiator hose by Dayco is also designed to meet Type EC electrochemical requirements as specified in SAE J168.

Top-quality Dayco Insulone Heater Hose distributes heated coolant to the heater core with less heat loss. Designed for use in cold climates where adequate heat transfer is crucial for the vehicle to run comfortably and economically. This hose has exceptional burst strength, heat resistance, and compatibility with all typical coolants and coolant additives, thanks to the synthetic EPDM rubber compounds and spiral reinforcement. A unique substance utilised in the insulating layer provides an additional layer of protection against heat loss. This hose, which is constructed with a black cover and has a temperature range of -40°F (-40°C) to +257°F (+125°C), is comparable to SAE 20R3, Class D-2.
