Description

The Dayco 71594 is an upper radiator hose designed as a direct replacement for 1991.5-1993 Dodge Cummins Turbo Diesel intercooled trucks with the 5.9L engine. It is constructed from EPDM material and meets SAE J20R4 specifications for reliable coolant flow. Unlike older hoses, modern failures are often due to unseen electrochemical attack on the rubber compound, requiring a squeeze to detect potential issues.
