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 helps it route to upper and lower coolant connections. It works as a direct-fit replacement across many classic GM, Ford and Mopar applications, including the 1980-1984 Ford F-150 5.0L / 5.8L and 1973-1975 Chevrolet Malibu 5.0L / 5.7L / 6.6L / 7.4L — see the "Vehicles it fits" section for the full list.
- Inside diameter: 1.50 in. at both End 1 and End 2
- Centerline length: 25 in. of flexible hose
- Position: serves upper and lower positions, including upper pipe-to-radiator and upper water-pump-to-pipe routing
- Country of origin: Pakistan
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.
