Keep coolant moving between the radiator, water pump and pipe with the Dayco Flex Radiator Coolant Hose 81201, a standard flexible radiator hose measuring 1-1/2 in. (1.50 in.) inside diameter at both ends and 25 in. of centerline length. Its flexible construction lets you route and cut it to fit a wide range of upper and lower coolant connections. It works as a direct-fit replacement across hundreds of classic GM, Ford and Mopar applications, including the 1973-1975 Chevrolet Malibu [V8-5.7L], 1980-1984 Ford F-150 [V8-5.0L], 1975-1979 Buick Skylark [V6-3.8L] and 1965-1967 Cadillac DeVille [V8-7.0L] — see the Buyer's Guide tab for the full list of 583 applications.
A hardened, cracked or swollen radiator hose can weep coolant, collapse under vacuum or let air into the cooling system. If a failed hose is behind your coolant loss or overheating, this flexible hose replaces it and helps restore proper coolant flow.
