Dayco Radiator Coolant Hose P/N:71977
Dayco 71406 lower radiator coolant hose for the 1988-1995 Toyota 4Runner V6 3.0L and other vehicles carries coolant between the radiator and the engine.
A lower hose that is cracked, swollen, soft or seeping can show up as coolant drips under the front of the vehicle or a temperature gauge that runs hot. Before you replace it, rule out a loose clamp, a weeping radiator outlet or a thermostat problem, because the hose may be sound and one of those may be behind the leak or the heat. One lower hose goes on the bottom of the radiator, and this listing is that one hose.
This hose fits the 1988-1995 Toyota 4Runner V6 3.0L, the 1988-1995 Toyota Pickup V6 3.0L and the 1981-1984 Toyota Starlet.
