Gates Radiator Coolant Hose P/N:23870
Gates 21170 upper radiator coolant hose for the 1992-1993 Hyundai Sonata 4-cylinder 2.0L and other vehicles carries coolant between the engine and the radiator. This Gates molded coolant hose is a new part, sold as a single hose.
A leaking, cracked or swollen hose can mean it is worn, though a faulty thermostat or radiator cap can also be behind coolant loss or overheating, so find the cause before replacing it. Look at the hose only with the engine off and cool.
This is the upper hose for the 1992-1993 Hyundai Sonata 4-cylinder 2.0L, the 1984-1985 Hyundai Pony 4-cylinder 1.6L, the 1984-1987 Pony 4-cylinder 1.4L, the 1986 Pony 4-cylinder 1.5L, the 1987 Pony 4-cylinder 1.6L and the 1979-1984 Mazda B2000 4-cylinder 2.0L, and every car named here needs just one hose.
