Our molded coolant hoses are manufactured to fit upper, lower, bypass, heater and other coolant applications with OEM-quality specifications, saving you time, costs, and energy from going to your OE dealer for radiator hose replacements. Approved for Marine applications. Gates’ curved hose line is the most comprehensive line on the replacement market.

• Engineered to resist electrochemical degradation, the leading cause of hose failure.
• Pre-shaped to fit and to ensure perfectly sealed conditions.
• Aramid or rayon knit reinforcement (depending on the application).

Designed to replace OEM hoses on today’s light duty vehicles for superior performance.

The Dayco molded radiator and by-pass hose features knitted reinforcement, a protective sleeve and a synthetic EPDM rubber construction for high strength performance, protection against abrasion and resistance to oil, mud, salt, road debris, ozone and coolants. It can also withstand temperature variations of -40°F (-40°C) to +257°F (+125°C). The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose. In addition to meeting SAE J20R4, Class D-1 requirements, this hose also meets Type EC electro-chemical requirements as specified in SAE J1684, which prevents inner tube deterioration caused by the build-up of static electric charges.

Designed as an aftermarket replacement for OEM manufactured branched cooling system hoses.

The Dayco branched radiator hose features an all EPDM construction that resists the effects of oil, mud, salt and ozone, and a knitted rayon reinforced inner tube that stands up to temperature ranges of -40˚F (-40˚C) to +257˚F (+125˚C). With leak-proof junctions that ensure long service life and unrestricted flow, this branched hose meets SAE J20R4, Class D-1, Type EC electro-chemical requirements as specified in SAE J168
