Dayco Radiator Coolant Hose P/N:71783
Dayco 71383 lower radiator coolant hose for the 1984-1995 Toyota 4Runner and other vehicles carries coolant on the lower side of the cooling system.
Coolant stains at a hose end, a soft or swollen hose, or cracks in the rubber can mean the hose is worn, though a loose clamp or a leaking water pump can be behind the same drip. If the hose is the cause, this one replaces it.
This hose fits the 1984-1995 Toyota 4Runner, the 1979-1995 Toyota Pickup and the 1988-1991 BMW M3. On the 1981-1995 Toyota Pickup and the 1988-1995 Toyota 4Runner it is listed for the L4-2.4L engine. This listing is one hose, and the 1984-1995 Toyota 4Runner takes one.
