Description
The Dayco 70778 Curved Radiator Hose is an engineered automotive component designed to maintain optimal engine temperatures by efficiently routing coolant between the engine block and radiator. Constructed from high-grade synthetic EPDM rubber, this molded coolant hose withstands extreme under-hood temperature variations ranging from -40 Degree Fahrenheit to +257 Degree Fahrenheit.
It features a dual inner-diameter profile with reinforced knitted rayon plies that deliver exceptional burst strength and structural integrity under high pressure. Built-in electrochemical resistance prevents premature inner tube decay caused by static electric charge accumulation, significantly extending the service life of your vehicle cooling system.
Ideal for automotive enthusiasts and professional mechanics seeking reliable performance and precise fitment.

good quality rubber
Fitted this onto my car last weekend because the old one was getting too soft. The dual inner diameter shape made routing much easier around the engine block. Only giving four stars because tracking took a bit long, but the part itself is solid and does the job well.
