Mack Coolant Hoses

The Dayco curved radiator 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 Deg. F (-40 Deg. C) to +257 Deg. F (+125 Deg. C). The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose.

Product Features:

• Meets SAE J20R4, Class D-1 requirements
• 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
• Provides excellent protection against external elements

The Dayco flex radiator hose replaces straight or molded radiator hoses on a wide range of engine applications. Precision molded in standard lengths, it features a knitted reinforcement and synthetic EPDM construction. This hose is designed to prevent splitting, ballooning and elongation as well as resist ozone and other detrimental environmental elements, coolants and temperature variations of -40 Deg. F (-40 Deg. C) to +257 Deg. F (+125 Deg. C). With corrugations that provide excellent hose flexibility without flattening or collapsing, the Dayco flex radiator hose also features a helical steel coil spring for increased flexibility.

• Not suitable for oil or heat transfer
• Meets SAE J20R4, Class D-2 requirements for improved service hoses

Gates Molded Coolant Hose is manufactured to fit specific applications. Similar to OEM specifications. Approved for marine applications.

Product Features:

• Specifically-engineered materials resist collapse under vacuum
• Engineered to resist electrochemical degradation, the leading cause of hose failure
• Pre-shaped to fit and to ensure perfectly sealed conditions
• EPDM tube: synthetic fiber knit reinforcement: heat-, ozone- and chemical coolant-resistant EPDM cover
• Meets requirements of SAE 20R4, class D2 and DIN 73411, class A (except for tolerances)
• Temperature Range: -40 Deg. F to +257 Deg. F (-40 Deg. C to +125 Deg. C)
• Note: Gates recommends replacing hose clamps each time a new coolant hose is installed
• Caution: Do not use for fuel or oil transfer applications
