Keep coolant moving between the radiator and engine with the Dayco coolant hose 81171, a standard flex radiator hose that routes engine coolant through the cooling system. Because it's a flexible hose, it bends to follow the factory routing on a wide range of classic and import applications — from the 1966-1969 Dodge Charger [V8-5.2L] and 1975-1979 Ford F-150 [V8-5.0L] to the 1967-1975 Chevrolet Camaro and 1993-1995 BMW 318I [L4-1.8L]. It covers 681 applications in all — see the Buyer's Guide tab for the full list.
This Dayco universal radiator hose flexes to form the bend a given application needs — whether a gentle curve or a tighter 90 degree coolant hose angle — making it a practical replacement when the original hose is cracked, swollen, or leaking. Replace a hose showing soft spots, bulges, or coolant seepage to help keep the cooling system sealed.
