Detailed Product Description

The Dayco Curved Radiator Hose 71959 is a branched radiator coolant hose made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. This hose features three inside diameters: 1 23/32 inches on both End 1 and End 2, and 31/32 inches on End 3, allowing it to connect multiple points within the cooling system efficiently. The outside diameters of End 1 and End 2 are both 2 1/16 inches, ensuring a secure fit with corresponding radiator and engine fittings.
