Features:

• Dayco® 90 Degree Molded Coolant Hose is designed for vehicles that require special heater hoses with a molded 90 degree elbow to fit tight engine compartment routings. Multiple 90 degree hoses can be used with Dayco plastic connectors to fit complex routings. Knitted reinforcement and all synthetic EPDM construction provides the high 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 hose replacements. The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose. Dayco’s Molded Radiator and By-Pass Hose has a convenient plastic hang strap for quick and easy merchandising. In addition to meeting SAE J20R4, Class D-1 requirements, this hose is now designed to meet Type EC electro-chemical requirements as specified in SAE J1684.
